1.0 GENERAL.

1.1 FEATURES.

The Model 1241 is the most sophisticated Two Way audio device on the market today. Features include:

♦Central station detection and automatic disconnect upon central station disconnect.

♦Compatibility with all digital communicators.

♦Microprocessor technology which provides a wide range of operating modes.

♦Activation by a trigger input immediately after the communicator hangs-up and/or by its built-in ring detector by

calling the system back after the alarm report.

♦When used in the call back mode, the system has the ability to bypass any other devices such as an answering

machine and/or downloadable communicator, which may intercept the call.

♦Multiple microphone inputs and the ability to drive multiple speakers.

♦Remote volume control of the microphone and speaker from the central station.

1.2 DEFINITIONS.

LINE HOLD - The immediate turn on of the audio module which allows the module to use the phone call generated by the digital

communicator when communicating with the central station.

CALL BACK - A procedure when the central station calls the premises after an alarm activation to initiate Two Way

communications. This can be used with or without the LINE HOLD mode.

VOX - Two Way communication which automatically switches the ability to talk to the talking party. Works like a

speakerphone.

MANUAL CONTROL - The opposite of VOX. The central station controls who talks and who listens with commands generated

from a Touch-Tonephone.

LISTEN ONLY / TALK ONLY - Both terms relative to the central station. LISTEN ONLY allows the central station to listen

without talking. TALK ONLY allows the central station to talk without listening.

2.0 REQUIREMENTS.

2.1 POWER.

Operating voltage: 9 to 14 VDC.

Current draw (standby): 80 mA max.

Current draw (active): 300 mA max.

2.2 SYSTEM.

The Eagle Model 1241 requires the following hardware:

1. A communicator/control panel which has a Two Way trip connection or a control panel with an Eagle Model 1405 or

Model 1406 Activation Module (when used in the line hold mode.)

2. Connections to power (+12VDC & Ground) and telephone (Tip & Ring). The 1241-S requires 6 VDC.

3. A minimum of one speaker (Eagle Model 2150 or equivalent) and one electret microphone (Eagle Model 2101 or

equivalent).

2.3 CENTRAL STATION.

1. A receiver with listen-in or Two Way capability (stays on line after kiss off).

Page 4

2. A Touch-Tonephone in parallel with the receiver line if used in the line hold mode.

3.0 CONFIGURING THE MODULE.

3.1 OPTION SWITCH DESCRIPTION.

The Eagle Model 1241 has many modes of operation. It can be custom configured for each installation. The

following is a description of each of the option setting switches. Recommended settings are italicized.

SW1:ON = Factory test / Demo Mode.

OFF = Normal operating mode.

This switch is only used to facilitate demonstration of the system to prospecting users. If using the full time call back

mode, moving this switch to the ON position (DEMO Mode) changes the number of rings before activation from six or

ten (selected by SW2) to just one (1) ring. The duration of the demo mode is set with SW2.

For normal operation, place SW1 is OFF .

________________________________________________________________

SW2 is dependent upon SW1 for its operation.

If SW1 is in the NORMAL MODE (OFF) and SW4 is ON then:

SW2:ON = 6 rings before answering.

OFF = 10 rings before answering.

If SW1 is in the NORMAL MODE (OFF) and ring detect is OFF (SW4 is OFF) then the operation of the Model 1241 is

independent of SW2's setting.

If SW1 is in the DEMO MODE (ON) then:

SW2:ON = Fast time-out of the shut down timer. Shuts down in one minute instead of five minutes.

OFF = Normal time-out of the shut down timer. Shuts down in five minutes.

There is no recommended setting for SW2.

_________________________________________________________________

SW3:ON = Activate in the "Two Way VOX mode" (automatic operation).

OFF = Activate in "Listen Only" mode (manual operation).

When the system is triggered by the trigger input or the ring detector, this switch controls how the Two Way audio will

activate. In some commercial applications where the possibility of a "hold up in progress" may occur, it is desirable

to have the system activate first in the "Listen Only" mode which will prevent the speaker from emitting any sound

when the system activates. If desired, the operator can then switch the audio to Two Way VOX after activation.

NOTE: When changing the Option Switches, always remove power, set switches, then

reconnect power. This insures that the new options will be read by the

microprocessor!

NOTE: When using the central station controlled relay connected to P8, SW1 must be in the

OFF position.

NOTE: It is recommended to have the module activate in the “listen-only” mode. Confirm

with local law enforcement if this is permitted.

Page 5

The module may be switched into either mode and back again (as many times as desired) independent of which

mode it was initiated.

Recommended setting for SW3 is OFF.

______________________________________________________________________

SW4: ON = Activate the system from ring detector.

(Note: system will also activate with trigger input when in this position, dependent on SW5.)

OFF = Activate the system with the trigger input ONLY (disable ring detector).

This switch controls the full-time ring detector. It DOES NOT control the "5-minute window after alarm activation" ring

detector. These are two separate modes and controlled separately.

If it is desired to have the system activate the ring detector, place this switch in the ON position.

If it is desired to have the system activate ONLY with the trigger input, then place the switch in the OFF position.

Recommended setting for SW4 is OFF.

_________________________________________________________________

SW5: ON = Activate immediately with the trigger input (Line-hold mode).

OFF = Set up the ring detector to answer after one ring.

When SW5 is in the ON position, the system will activate immediately with the trigger input. (This occurs when the

digital communicator is shut down with a kiss-off from the Central Station.) A trip from the communicator/control

panel or an Eagle Model 1405 or 1406 activation module is required.

When SW5 is in the OFF position a trigger input will activate a five (5) minute window. The 1241 will answer the

phone line as soon as it sees one ring within this window. The system will ignore any invalid phone calls (see section

4.2). When the five minute window expires, the system will ignore any additional phone calls (unless programmed for

"call-back" mode with SW4).

Recommended setting for SW5 is ON.

________________________________________________________________

SW6: ON = Positive edge trigger on trigger input.

OFF = Negative edge trigger on trigger input.

When SW6 is in the OFF position, the system will interface with digital communicators that provide a trigger input that

is at 1.5 VDC or less when NOT reporting and switch to 2.5 VDC or greater when reporting.

When SW6 is in the ON position, the system will interface with digital communicators that provide a trigger input that

is at 2.5 VDC or greater when NOT reporting and switch to 1.5 VDC or less when reporting.

SW6 is installation dependent. There is no recommended setting.

NOTE: This mode is independent of the full-time call back mode. If it is desired that the only time

the module is to answer is when the ring detector has been set up with the trigger input,

set SW4 OFF (trigger only).

NOTE: Before selecting this option, determine which type of trip will be used by measuring the DC

voltage at the trigger input when connected to the communicator. (Positive lead of the voltmeter

on Terminal TRIP of the 1241, negative lead of the voltmeter on Terminal GND on the 1241.)

TABLE 2 DESCRIPTION.

+12 and GND:+12 VDC and GROUND input, respectively.

TIP and RNG: Telephone T1 and R1, respectively (usually brown and gray on RJ-31X, respectively.)

TRIP:Trip input into the module. Positive or negative edge. Set edge with SW6. Maximum input voltage should not

exceed 14VDC. Consult factory for assistance with your equipment.

ANS HGUP: This input is only used when it is desired to operate the 1241 as a Hands Free "Speaker Phone" in

addition to its normal function. Connect GND and ANS HGUP to a Normally Open switch (if desired). Also used

when using Model 1405 Activation Module. See paragraph 4.3.

N.C. and N.C.: Normally Closed relay contacts for local alarm silencing. These contacts duplicate pins 4 and 5

(yellow & green wires) of P1. During Two Way, this connection is opened. This relay is used to disconnect a local

alarm for Two Way. If the additional contacts are required to release an additional annunciator, the contacts on P1

must be used via accompanied relay cable assembly, P/N 117000.

MIC1: The function of this terminal is dependent on P3. If P3 is set on pins 1 and 2, this is the signal input for an

electret microphone. If P3 is set on pins 2 and 3, then this is the signal input for a power microphone (low impedance

microphone). See Paragraph 3.3 for details.

MIC POWR: This is power output for all electret microphones, or any microphone which use +5 VDC for power.

MIC2, MIC3 and MIC4: These are the inputs for electret microphones (Eagle Model 2101). These inputs are

amplified on the module. Any combination of inputs may be used (including terminal MIC1).

SHLD:This is the ground for all electret microphones. This may also be used for a ground connection for a power

microphone.

SPK and SPK: These are the talk-back speaker outputs. Speakers with a minimum of one watt power rating are

recommended (Eagle Model 2150). The total impedance of the speakers connected to these terminals must

be 8 ohms or more. See DIAGRAM 1 for multiple speaker connections.

GREEN GROUNDING WIRE: The 1241 requires EARTH GROUND for lightening protection. Connect EARTH

GROUND to this wire. EARTH GROUND must be connected to maintain warranty! Failure to connect will void

warranty!

WARNING!: DO NOT CONNECT AC VOLTAGE TO +12 AND GND - DAMAGE WILL OCCUR!

NOTE: It is recommended to connect the 1241 to the premise side of the RJ-31X. If using the

ring detect mode and the communicator/alarm panel has a download feature (which is

being used), the 1241 must be connected across the street side of the RJ-31X and the

communicator must be programmed to answer the phone a minimum of one ring before

the 1241 is programmed to answer the phone.

NOTE: Shielded wire must be used for all remotely mounted electret microphones!

WARNING: Earth Ground must be connected for proper lightening protection!

Failure to connect voids warranty!

3.3 JUMPERS.

P3 - This sets the type of microphone used on MIC1 (only). Set the shunt block across pins 1 and 2 (default) when

using an electret microphone (Eagle Model 2101). When using an amplified microphone, set the shunt block across

pins 2 and 3.

If your unit was shipped with a jumper wire in place of the header, MIC1 is set for use with an electret microphone

(Eagle Model 2101). If it is desired to use an amplified microphone, cut the jumper.

3.4 ADJUSTMENTS/INSTALLATION.

SPK - Used to adjust the gain of the speaker during "Two Way VOX" mode only; CCW - increases gain; CW -

decreases gain. Use an amply rated speaker, 1 watt or more (Eagle Model 2150 or equivalent).

MIC - Used to adjust the gain of the microphones during "Two Way VOX" mode only; CCW - increases gain, CW -

decreases gain.

3.5 MICROPHONE AND SPEAKER INSTALLATION.

3.5.1 LOCATION.

A microphone and speaker can cover a range of up to 2500 square feet. This is dependent on the environment in

which they are installed. Installation is recommended at or near system keypads with a minimum of one per floor,

excluding basement.

3.5.2 SEPARATION.

It is required to install the microphone and speaker no less than three (3) feet from one another. This will prevent any

feedback in the Two Way VOX mode.

3.5.3 QUANTITY OF MICROPHONES AND SPEAKERS.

Microphones. The Model 1241 is designed to handle up to four microphones (one per input). If additional

microphones are required they may be installed in a parallel configuration. If this is utilized, it is recommended to

configure ALL used inputs the same (all single or all double). This will prevent unbalanced inputs. Inputs not used

should have no connection.

CAUTION! - Microphone(s) and speaker(s) must be mounted a minimum of three feet from each other or

feedback may occur.

Page 9

Speakers. The Model 1241 is designed to drive up to four speakers. Total speaker impedance must be eight (8)

ohms or greater. (See section 3.2 for wiring diagram.) If additional speakers are required, or if additional volume is

desired, the Eagle Model 1402 SPEAKER EXPANSION MODULE must be used.

3.6 COMMUNICATOR PROGRAMMING.

When programming the digital communicator, it is advised to begin the "TELEPHONE NUMBER" with "∗∗70" (tone

dialing) or "1170" (pulse dialing). This will allow uninterrupted communication when the subscriber has call waiting.

4.0 ACTIVATION.

4.1 IMMEDIATE TURN ON.

When SW5 is set in the ON position, the module will activate when a trigger is received at the TRIP terminal. This

trigger must correspond with the completion of the communicator's alarm report (kiss off from the Central Station).

When the Two Way audio module is activated in this mode, the operator, if listening at that time, will hear a two tone

"beep-bop" acknowledgment generated by the module. This is the operator’s notification that the module is on and

active. The red LED will illuminate while active.

The operator can control the operation of the module using a Touch-Tonephone per Paragraph 5.0.

4.2 USING RING DETECTOR.

4.2.1 DESCRIPTION.

FULL TIME CALL BACK.

When the ring detector option is selected for the module (SW4 is ON), the module will answer in the programmed

number of rings (SW2). When this feature is programmed ON, it is valid at all times, i.e., anytime the phone rings the

programmed 6 or 10 times, the Model 1241 will pick up the line and the red LED will illuminate while active.

FIVE MINUTE WINDOW.

The Model 1241 has a call back mode which activates upon a trip. The window is initiated from the trip input. This

sets up the system to answer an alarm which has just been reported by the digital communicator (SW5 is OFF). The

operator will have 5 minutes in which to call back the system and have it answer within one ring. This feature allows

call back only within five minutes of an alarm activation. While active, the red LED will illuminate.

If the five minute call back timer has elapsed, SW4 has been set to activate the system only on the trigger input (OFF)

and SW5 has been set to activate the five minute call back window (OFF), then the system will no longer pick up the

call; no matter how many rings occur. If SW4 has been set to activate the system both with the trigger input and the

ring detector (ON), SW5 has been set to answer within five minutes of an alarm activation (OFF) and the five minute

call back timer has elapsed, the module will revert to the number of rings programmed using SW2 after the five

minute time-out has expired.

These two features are independent of each other. That is, the module can be configured to answer the phone in the

programmable 6/10 rings (valid anytime) and/or answer the phone within one ring after an alarm activation (five

minute window).

4.2.2 CALL ANSWERING.

NOTE: The central station receiver must be capable of a “listen-in” function, i.e., the receiver must hold the

phone line open until an operator can pick up the line.

Page 10

When the system detects the programmed number of rings, it will pick up the phone line and send a series of 3

"beeps" as an answer acknowledgment. The system now has the line, but Two Way is NOT active.

The operator has 15 seconds to press (and release) the ** (asterisk) key to activate the module.

If the ** is not sent in 15 seconds, the system will hang-up.

When the ** is received, the system will generate a two tone "beep-bop" acknowledgment and the red LED will

illuminate.

4.3 MANUAL ACTIVATION (HANDS FREE SPEAKERPHONE).

When a momentary, normally open "answer/hang-up" switch is connected between GND and ANS HGUP, the 1241

can operate as a speaker phone. Pressing the switch will cause the system to come on-line in the "Two Way VOX

mode”. The red LED will illuminate while active. Pressing the switch again will cause it to hang-up.

The timers, "beep" tones and Touch-Tonedigits will be disabled in this mode.

The switch must be pressed to hang-up the system as it will NOT time out automatically.

5.0 CONTROLLING THE MODULE.

After the module has been successfully activated by one of the methods described above (other than the manual

speakerphone mode), the operator can control the operation of the system using a Touch-Tonephone in the

following manner:

To switch to high gain "listen only", press and release 33. To switch to "Two Way VOX", press and release 22. To

switch to high volume "talk only", press and release 11. The operator can switch back and forth between these

modes as often as one wishes independent of the mode in which the module was in when activated.

The Model 1241 provides five (5) minutes of Two Way. During Two Way, the module will generate a "beep" once

every minute. Upon the fourth and final minute of Two Way the module will generate a two tone "beep bop" warning

the central station that there is only one more minute of Two Way before the module automatically disconnects.

These beeps will be heard at the premise when module is in the "Two Way VOX" mode or in the high volume "talk

only" mode. These beeps will always be heard by the central station. The one minute progress beeps may be

disabled by cutting the resistor at the top edge of the module (see DIAGRAM 2). The activation and the final minute

warning beeps will still operate even if the resistor is removed.

The operator can control the operation of the module using a Touch-Tone phone per Paragraph 5.0.

CAUTION!: If there is a loud, continuous background noise, such as a radio, the central station operator

should not attempt to increase the gain of the Model 1241, as this may cause the system to lose

the ability to recognize the tones from the central station. If the module “locks-up” into the

high gain “listen-only” mode, press and hold 22 for a minimum of 5 seconds. This should

unlock the module. Repeat if necessary.
