WIRING DIAGRAMS
Install module wiring in accordance with appropriate wiring diagrams.
(Figure 3 and Figure 4)
The module relays have a maximum ON resistance of 25 ohms. This resis-
tance plus the wiring resistance to the panel must be less than the maximum
zone wiring resistance stated in the panel manual.
INPUT TRIGGERS/SOUNDER ACTIVATION
Many panels can be programmed with triggers which are auxiliary relays that
activate upon an alarm condition. Two inputs are used to signal the module
to activate device sounders. The first is configurable by DIP switch to one of
two modes; bell in or smoke trigger. When in the bell mode, the module will
follow a valid coded signal from a Bell Out/NAC circuit consisting of high to
low, then low to high for less than 1.9 seconds each. In smoke trigger mode,
while the input is held high, the module will synchronize the detectors in a
Temporal 3 pattern.
The second input is for a CO trigger ; the CO trigger input allows a single mod-
ule to have CO silence/hush capability and allows multiple module installa-
tions to have all sounders activated in Temporal 4 in the event of a CO alarm.
While the CO trigger is held high, the module will synchronize the detectors
in a Temporal 4 pattern. After 30 minutes in Temporal 4 alarm, the time period
between the Temporal 4 pulse will change from 5 seconds to 60 seconds.
Note: CO trigger may not be used with UL 864 panels. All detectors will sound
with no triggers connected, however, hush capability is not enabled.

POWER UP AND COMMUNICATIONS
COMMUNICATIONS ChECk (2-WIRE ONLy)
Upon power up, the module will send a request for communication check. All
compatible detectors on the loop that understand the communication protocol
will respond. If all detectors respond correctly, the green LED will blink once
every 5 seconds. If the module does not get a response, it will turn off the
green LED and continue to try every 2 minutes until a response is received.
SMOkE MAINTENANCE INqUIRy
The module sends a smoke maintenance inquiry to the detectors every 24
hours. (Compatible 2-wire detectors only) If a response indicating a mainte-
nance problem is received, the red LED on the module will blink once every 5
seconds and a smoke maintenance condition will be indicated to the panel. It
is likely that the detector needs to be cleaned or replaced, refer to the detector
instruction manual for maintenance instructions.
fREEzE TROUBLE INqUIRy
The module sends a freeze trouble inquiry to the detectors every four hours.
(Compatible i
3 Series 2-wire smoke detectors only) If a response indicating a
freeze problem is received, the red LED on the module will blink once every
10 seconds and a smoke maintenance condition will be indicated to the panel.
TESTING
Modules must be tested after installation and following periodic maintenance.
Testing should be performed at least once per year.
NOTE: Before testing, notify the proper authorities that the system will be tem-
porarily out of service. Disable the zone or system to prevent any unwanted
alarms.
Ez WALk TEST
The communication loop between the 2-wire modules and detectors can be
manually tested by putting the module and detectors into EZ Walk test mode.
This feature is for use with System Sensor detectors (i
4 series model COSMO-2W
and i 3 series model 2WTA-B) installed with the model COSMOD2W module.
The EZ Walk loop test verifies the initiating loop wiring and provides visual
status indication at each detector:
1. Ensure proper wiring and power is applied. Wait approximately 5 min-
utes from power-up before performing the EZ Walk test. The green LED
on the module must be blinking indicating the module is in ready/
standby mode to start the EZ Walk mode.
2. Locate the EZ Walk recessed test switch located behind the module cover
(See Figure 1). Depress the test switch with a small screwdriver. The yel-
low LED will blink showing that the module and detectors are in EZ Walk
mode for 5 minutes.
3. Observe the LEDs at each detector to make sure the green LED is double
blinking every 5 seconds as listed in Table 3.
4. At the end of the five minute period, the module will terminate EZ Walk
and the yellow LED will stop blinking. The EZ Walk test period can be
extended by pressing the test switch multiple times. Each press will add
5 minutes of additional time.
If a module or detector fails the test, its wiring should be checked. If the
module still fails, it should be replaced. Notify the proper authorities when all
testing has been completed.
NOTE: The EZ Walk loop test should not be used in lieu of functional testing
(alarm, trouble and other functional tests) of the system.
