Refer to the control panel installation manual for detailed system information. If the module will be installed in an existing operational system, inform the operator and local authority that the system will be temporarily out of service. Disconnect power to the control panel before installing the module. The i4 COSMOD2W, 2-wire interface module, offers additional functionality including: • Ability to query for a “need for maintenance” condition from 2-wire i4 series model COSMO-2W and i3 series model 2WTA-B smoke detectors • One relay is available to indicate a multitude of maintenance conditions at the control panel Notice: This manual should be left with the owner/user of this equipment. 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. SS-500-004 • All conditions are displayed at the module and at the detector • EZ Walk test mode allows the installer to easily verify that all detectors on a loop are operational • Allows 2-wire smoke detectors to be used on any compatible 4-wire control panel and provides Style D wiring on the detector loop FEATURES • Compatible with System Sensor i4 series combination CO/smoke detectors and System Sensor i3 Series smoke detectors models 2WTA-B or 4WTA-B. • Allows up to 12 compatible devices including the i4 series combination CO/smoke detector to be integrated with a panel 1 I56-3871-001 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. • Allows sounder activation of all detectors on loop in either Temporal 3 or Temporal 4 pattern 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. 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. FIGURE 1: MODULE FRONT VIEW 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. Green LED Yellow LED Red LED Blue LED INSTALLATION MOUNTING The module can be mounted to a 4-11/16 inch back box or inside a listed, dedicated 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.

SLOTS FOR MOUNTING TO 4-11/16 JUNCTION BOX 0331-00 No Power/Non-operational Power is not applied to the module or communication between the module and the detectors on the loop is unsuccessful. 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). 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. 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. 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. 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. 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. WARNING Remove power from alarm control unit or initiating device circuits before installing detectors. 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.

(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. 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. TESTING Modules must be tested after installation and following periodic maintenance. Testing should be performed at least once per year. 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. 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 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. 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: CO trigger may not be used with UL 864 panels. All detectors will sound with no triggers connected, however, hush capability is not enabled.

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. NOTE: The EZ Walk loop test should not be used in lieu of functional testing (alarm, trouble and other functional tests) of the system. TABLE 3: ez walk test detector modes 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 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. detector green led detector red led Double Blink 5 Seconds OFF Out of sensitiviy OFF Double Blink 5 Seconds freeze condition OFF Double Blink 10 Seconds proper operation FCC Statement This device complies with part 15 of the FCC Rules.
