DMS-III Installation and Operation Manual

INSTALLATION

INSTALLATION GUIDELINES

Inspection:

Please examine your DMS III for any damage that may have been sustained during

shipping. If any is noted, please notify the shipper immediately and retain the pack-

aging for inspection by the shipper. The package should contain the DMS III, 16

vac@600 ma wall power transformer and this manual.

Mounting:

Mount the DMS III where it will be visible and rear panel accessible. Four (4) screw

holes are provided for mounting. The DMS III may be set on a desktop, mounted

on a wall or as part of the new RA-1, “Rack-Able” mounting shelf.

Connecting user equipment:

Follow the designators on the rear of the DMS III. Page six lists the function of all

relays and remote control inputs. The analog audio output and digital I/O are also

listed on the rear chassis.

Configuring For Backup Switching:

• Connect the (MAIN) source equipment to Input 1.

• Connect the (BACK UP) source equipment to Input 2.

• Connect the destination equipment to the OUTPUT terminal.

• Shields may be connected to the terminals labeled “EG”

Automatic Operation:

When the main signal is lost, the DMS III will sense the loss and start timing. When

the time-out is reached, the DMS III will switch to the back-up source. When the

signal returns and after the restore time has been reached (if enabled), the DMS III

will automatically switch back to the main source. Please refer to page 7 for option-

al detection modes (SW2-7).

Manual Operation:

Pressing the “XFER” switch once will switch to input 2 and light the IN-2 indicator.

Press the switch again to switch back to input one and extinguish the IN-2 LED.

Pressing the RESET switch will always return the unit to input one.

NOTE:

The DMS III is

designed to route Input

1 to the output in the

event of a power or

unit failure.

DMS-III Installation and Operation Manual

INSTALLATION

INSTALLATION GUIDELINES

Remote Control Description

• Mute This input is used to mute the sonalert alarm.

The sonalert may be disabled by removing JP3 on the

rear panel.

• Reset This input clears all alarms.

• Ext The “EXT” (external) input will trigger immediately

and switch to the backup source.

This may be used to monitor STL or satellite squelch

relay, etc.

• Arm/Disarm This input allows the disarming or arming of the

system. This is a toggle action function.

• Xfer (Hidden on some units) Allows the switching back and forth (toggle) between

the two inputs. The In-2 LED indicates that input 2 is

selected.

NOTE: All of the above inputs (pulled up to 5 volts) require momentary ground

closures. Inputs are 5-volt TTL/CMOS compatible,

• Transfer (Xfer) Alarm Relay (K1-A/B) The 2PDT relay is activated after the timed

loss of signal and relaxed when the signal returns (this

is determined by the setting of the RESTORE timing

switches).

• Pulse Relay (K2) This SPDT relay is activated for one second after the

timed loss of signal. Great for rebooting external

equipment.

• Tripped Relay (K3) This SPDT relay will close when any alarm is trig-

gered and stay latched until manually reset.

• Armed/Disarmed Relay (K4) This relay closes when the system is armed. The relay

may be configured as normally open or closed.

• Ext Relay (K5) This SPDT relay is activated when an external trigger

is activated.

Note: On some chassis, the normally closed relay K5 contact reads in error,

“KGNC”. The correct label should read K5NC.

NOTE: The relay designation of NO, refers to the Normally Open contact in the

OFF condition. The relay designation of NC, refers to the Normally Closed con-

tact in the OFF condition. C refers to the common or wiper of the associated

relay.

DMS-III Installation and Operation Manual

INSTALLATION

It is recommended that all cables connected to the DMS III be looped through fer-

rite cores to suppress RF. Surge protection with RF filtering such as the Tripp Lite

“ISOBAR 4” is also suggested for the power transformer. The purchase of an

inexpensive uninterruptible power supply (UPS) will provide back up in case of

power outages.

WEBSITE:

additional information

CAUTION!

Installation of the

DMS-III in high RF

environments should be

performed with care.

Shielded cable is sug-

gested for all control,

audio inputs and out-

puts. All shields should

be tied to the “CHAS-

SIS GROUND” termi-

nal. The station

ground should be con-

nected to the chassis

ground screw (CH1)

located behind J1 as

viewed from the rear.

tion devices, check out

DMS-III Installation and Operation Manual

PROGRAMMING

PROGRAMMING GUIDELINES

Switch and jumper Setup:

Jp-3 Enables the sonalert (buzzer)

Jp-6 Selects either 75, 110-ohm or no termination for input one

Jp-7 Selects either 75, 110-ohm or no termination for input two

SW2-7, OFF, monitors for both a digital error and/or analog silence alarm.

NOTE: Both digital error and silence must be restored before the

alarm is cleared.

SW2-7 ON, monitors for a digital error only.

SW2-8 Not used (feature creep).

Delay timing setup:

The DMS III time delay is set via SW 1, the 8-position dipswitch and SW2 switch

6 .

The default for SW-2-6 if OFF. This provides TWO second resolution. To provide

longer delay time resolution, turn ON SW2-6, which will provide 20 second resolu-

tion. The switches are set at the factory for a 6 second delay (SW 1-1 & 2 ON and

SW 2-6 OFF). Each switch has a digit value as shown in the two tables below. For

the factory default setting, as shown in the two-second-resolution table below, we

have turned ON switches one and two. Switch one represents a one-digit value,

while switch two represents a two-digit value.

We add these two digit values together to obtain a total digit value of three. Each

value is given a time delay of two or twenty seconds, so we therefore multiply the

total digit value of three by two (or 20) to obtain six (or 60) seconds.

NOTE: The table on the page refers to the time delay in seconds.

Restore timing setup:

The DMS III restore time delay is factory configured for 20-second resolution only.

Restore delay is set by the first five positions of dipswitch SW2. The default for

these switches is OFF. Each switch has a digit value as shown in the table below

and refers to the restore time delay in seconds.

OPERATION GUIDELINES

Front panel switches:

“XFER” switch

Allows the switching back and forth (toggle) of inputs one and two. The In-2 LED

indicates that input 2 is selected. Use a non-metallic object to operate the recessed

test switch (Early versions only).

Mute switch

Used to silence the sonalert. To disable the sonalert, simply remove JP3.

Arm/Disarm Switch

Arms and disarms the DMS III. When armed, the front panel “ARMED” LED will

be illuminated and the armed relay will be closed.
