This product is intended for use in ordinary indoor locations.
GENERAL DESCRIPTION
The i4 series module is designed to interface between compatible i4 series
combination CO/smoke detectors (Model COSMO-2W and COSMO-4W) and
compatible security/fire panels. It can also be used to retrofit compatible i4
series detectors into an existing loop of i3 smoke detector models 2WTA-B or
4WTA-B, without adding wires. The module interprets signals and translates
them into a separate smoke zone and a separate CO zone, each with alarm
and trouble signals. When signaled by the panel, a module will synchronize
connected detector sounders in either Temporal 3 or Temporal 4 pattern. Local
status indication is provided by 4 LED’s and a 3 position DIP switch enables
user configuration.

VISIBLE ANNUNCIATON
The i4 series interface module has four visible LED’s: The green LED is a supervisory LED; it blinks during power on, reset, and during normal operation.
The yellow LED is used to indicate a loop wiring fault and will blink when it
is in EZ Walk test mode. The red LED signals smoke events; it blinks during
smoke maintenance events and lights constantly during smoke alarm events.
The blue LED signals CO events; it blinks during CO trouble or CO end-of-life,
and lights constantly during CO alarm.

NORMAL (STANDBY)
The module is powered and detectors on the loop are operating normally.
NO POWER/NON-OPERATIONAL
Power is not applied to the module or communication between the module
and the detectors on the loop is unsuccessful.
LOOP WIRING FAULT
If an open circuit occurs on the loop, the module will indicate the condition
by illuminating the yellow LED. 2-wire units will then power the style-D terminals. When the wiring issue on the loop has been resolved, the module will
turn the yellow LED off.
EZ WALK TEST MODE
This indicates the module and detectors are in EZ Walk Test Mode. See “EZ Walk
Test” section for instructions on how to initiate and perform the EZ Walk test.
ALARM SMOKE/ALARM CO/ALARM SMOKE & CO
A smoke alarm will be indicated by the red LED. A CO alarm will be indicated
by the blue LED.
A smoke alarm is not self-restoring. Once a smoke alarm has been signaled,
the red LED will illuminate until the module is reset by removal of power.
Note: On some panels, resetting a smoke alarm may require additional steps
at the keypad to clear the trouble conditions on CO and smoke maintenance zones due to power loss to the module.
A CO alarm is self-clearing. Once a CO alarm has been signaled, the blue LED
will illuminate. Once the initiating device ceases to signal the CO event, the
blue LED will turn off. If a CO alarm is signaled, and not cleared, prior to a
smoke alarm condition, the module will keep both the blue and red LED’s
illuminated. If a smoke alarm is signaled first, the module will not be able to
receive notification of a CO alarm condition and will not be able to report it
to the panel.
MAINTENANCE
This condition means one or more detectors on the loop have a smoke maintenance issue. See “Smoke Maintenance Inquiry” section for further details.
FREEZE TROUBLE
This condition means one or more detectors on the loop are measuring the
ambient temperature is near the freezing point. See “Freeze Trouble Inquiry”
section for further details.
CO TROUBLE
The module can be notified of a detector with a CO trouble condition. All CO
trouble conditions will be reported on the CO zone and displayed with a blinking blue LED. The module is not able to determine the number of detectors
that have a CO trouble condition or which trouble condition exists.
INSTALLATION
MOUNTING
The module can be mounted to a 4-11/16 inch back box or inside a listed, dedi-
cated enclosure. When mounting inside an enclosure with pre-stamped holes,
it may be easier to align the bottom screw hole first. It is not necessary to use
the module cover when mounting inside an enclosure.

WIRING GUIDELINES
All wiring must be installed in compliance with the NFPA 70 standards, National Electrical Code, applicable state and local codes, and any special requirements at the local Authority Having Jurisdiction (AHJ).
The screw terminals in the mounting base will accept 14-22 gauge wire. Wire
connections are made by stripping approximately ¼” of insulation from the
end of the feed wire, inserting it into the proper base terminal, and tightening
the screw to secure the wire in place. Do not put wires more than 2 gauge
apart under the same clamping plate.
Note: The module must be installed in the same room and within 20 feet of
the panel and enclosed within conduit or equivalently protected against mechanical injury.
WARNING
Remove power from alarm control unit or initiating device circuits before installing detectors.

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 resistance 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 module to have CO silence/hush capability and allows multiple module installations 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 maintenance problem is received, the red LED on the module will blink once every 5
FREEZE TROUBLE INQUIRY
The module sends a freeze trouble inquiry to the detectors every four hours.
(Compatible i3 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 temporarily 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 (i4 series model COSMO-2W
and i3 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 minutes 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 yellow 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.
