Compatibility
This annunciator panel meets or exceeds all UL-2524, IFC, NFPA and Local Requirements. It is functionally
backwards-compatible with all previous versions of the Model 1221 series and has an internal universal DC
power converter that enables operation from any DC input voltage between 12-55 VDC.
Main PC Board
Figure 2 shows the layout of the main PC board and the locations of the DIP switches (shown in factory
default settings, and in Table 3). Figure 2 also shows connector locations that are connected to the DAS
equipment and the building’s Fire Panel.

LED Panel Indicators
This annunciator panel has 9 LEDs on it that show the status of the equipment in the DAS. The functions
are described below:
LED Functions
LED DESCRIPTION
1 AC Power Normal (Green when AC power is on to the DAS equipment)
2 AC Loss (normally OFF, Amber if AC power is down)
3 BDA Trouble or Oscillation (Normally OFF, Amber if there is a problem)
4 Donor Antenna Trouble (Normally OFF, Amber if there is a problem)
5 Donor Antenna Disconnected (Normally OFF, Amber if the antenna is
disconnected)
6 Battery Charger Alarm (Normally O, Amber if there is trouble)
7 Battery Capacity (Normally OFF. If the DAS backup battery has less than
30% capacity, this LED is Amber)
8 System Component Alarm (Normally OFF. If other system components have alarm
troubles, this LED is Amber)
9 Communications or Panel Trouble (Normally OFF, Amber if the panel has any kind
of problem such as AA batteries dead, or a short (or open) on any alarm wires
connected to it from the DAS equipment)
If there is a communications fault with one of the alarms, the specic alarm LED will designate the problem
by turning RED.
The Push-to-Test Button on the panel’s front illuminates all of the LEDs. Unlike previous versions of the Model
1221, it does not actuate the relays going to the Fire Panel.
Installation
1. Remove the required plastic knockouts (see page 14) for the installation and cable routing method
and install any required ½” conduit ttings, being careful not to damage or scrape the PC board with
any installation tools.
2. Mount the unit to a wall using the Mounting Kit and Drill Template.
3. Attach the alarm connections from the DAS equipment per the wiring diagrams
shown in Figures 3, 4, 5 and 6 using CAT 5 or CAT 6 cables up to 5000 feet in length. If longer cable is
required, contact Technical Support. Use the supplied screwdriver to connect wires to the plugs.
4. Use the supplied zip ties and mounting pads to organize all wire bundles so they do not cause
interference or crimping when the door is shut and locked.
5. Install the four AA batteries into the holder and apply DC power to J10. If the unit is not going to
be powered after the installation for a long period of time, remove at least one of the batteries to
avoid depleting the battery pack when power is o.
Self-Test
The included 2-pin test connector can be used to independently check the Panel and conrm its operation
without any other DAS equipment connected.
To do the self-tests, remove plugs J1-A and J1-B, then set the DIP switches (1-9) on SW1 to ON and SW2 to
the factory default settings shown in Table 3 on Page 12. Conrm that all LEDs are OFF, except AC Power
Normal which should be GREEN. The test plug can be connected between the input ports on J1-A and
J-1B to simulate alarm signals for each type of alarm. The corresponding AMBER LEDs on the Panel front
should illuminate for each type of alarm. Don’t discard this plug; keep it in the Panel to enable further
troubleshooting if required.
Buzzer
One of the requirements of UL-2524 is that an audible alarm be included as part of the Panel that can
ONLY be silenced for up to 24 hours by unlocking the Panel and pressing the silence button inside. This
requirement is to keep unauthorized persons from turning the buzzer o. If the DASAlert Panel is located
close to the building’s Fire Panel (which has an audible alarm triggered by the DAS alarms) then the
DASAlert buzzer can be permanently disabled by setting DIP switch SW-2 (switch 9) to the ON position. If
the key is lost, contact Technical Support for alternative ways to silence the buzzer.
The buzzer has three audible modes:
• It will buzz once every 10 seconds if any alarm is triggered.
• It will buzz once per second if there is a communications fault of if the Panel’s backup AA battery pack
is dead or not installed.
• It will buzz continuously if there is no alarm when the silence button is depressed.
DC Power for the Panel
The Panel has an internal universal DC power converter that enables operation from any DC input voltage
on connector J10 between 12 -55 VDC. The supplied 120 VAC to 48 VDC socket-mounted power supply can
be connected here. This DC voltage can also be supplied from the Backup Battery Unit (BBU) that powers
the BDA. There is an indicator that glows GREEN when DC power is present. The current consumption
is very low so the wires providing this power can be very long, especially if the supplied 48 VDC power
supply is used.
The current consumption is as follows at typical voltages:
Maximum Current Consumption:
12 VDC 100 milliamps
24 VDC 50 milliamps
48 VDC 24 milliamps

Wiring Options
There are several dierent ways to wire the DAS equipment and power to the Panel.
The method used depends on the following:
• How many alarms are provided by the DAS equipment. Frequently the only DAS equipment in the
installation is the BDA and BBU, hence the “Other System Components” input to the annunciator
will not be connected.
• Frequently a “SYSTEM OSCILLATION” alarm is not provided by the BDA and this alarm input will
not be connected to the Panel.
• The length of the cables from the DAS equipment to the Panel is another variable. If the cables are
shorter than 20 feet, then no End-of-Line Resistors (EOLR) are required by code to supervise the
connections.
• The location of the power source for the Panel can vary. It can be powered from the supplied 120
VAC to 48VDC socket mounted power supply that could be located near the Panel in the Fire
Command Center, or this unit could be in a headend near the BDA and BBU. The panel can also be
powered from the BBU.
• Figures 3, 4, 5 and 6 show some options using shielded CAT 5 or CAT 6 cable. In some cases the
shielding is used to carry signals and must be isolated from the chassis or earth ground and other
cables.
