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. 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. FIGURE 1: MODULE FRONT VIEW 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 MOD2W allows a control panel to receive a “need for maintenance” signal from two–wire i3 series smoke detectors, model numbers 2W–B, 2WT–B and one 2WTR-B. The module uses a form C zone relay to initiate “out of sensitivity” and “freeze trouble”, a form A zone alarm relay and a second form A zone relay to indicate loop fault. An EZ Walk Test puts all detectors on the loop into a Walk Test mode for easy verification of detector loop wiring. The module allows 2-wire smoke detectors to be used on any compatible 4-wire control panel and provides Style D wiring on the detector loop. Green LED Yellow LED Red LED EZ Walk Test Switch VISIBLE ANNUNCIATON The MOD2W has three visible LED’s: The green LED is a supervisory LED; it blinks during power on, reset, and during normal operation. The yellow LED SS-560-000 S0331-02 1 I56-4001-000 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. WARNING Remove power from alarm control unit or initiating device circuits before installing detectors. NORMAL (STANDBY) The module is powered and detectors on the loop are operating normally. WIRING DIAGRAMS Install module wiring in accordance with appropriate wiring diagrams. (Figure 3) NO POWER/NON-OPERATIONAL Power is not applied to the module or communication between the module and the detectors on the loop is unsuccessful. 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. 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. NOTE: If 2–wire i3 detectors are used in conjunction with a style D initiating circuit, the MOD2W must be used to provide that capability. Ground fault on a module’s 2-wire loop can be indicated at a control panel if the control panel is capable of ground fault detection on the power supply to the module and meets NFPA 72 ground fault indication requirements for initiating device circuits. The installer must verify that capability. 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 A smoke alarm will be indicated by the red LED. TABLE 2: DIP SWITCH CONFIGURATIONS 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. 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. DIP SWITCH # 1 DIP SWITCH # 2 DIP SWITCH # 3 ON (DEFAULT) Unused Smoke Maint on Smoke Trouble and Form-B Maint Relay Unused OFF Unused Smoke Maint on Form-B Smoke maintenance Relay only Unused POWER UP AND COMMUNICATIONS COMMUNICATIONS CHECK 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. 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. SMOKE MAINTENANCE INQUIRY The module sends a smoke maintenance inquiry to the detectors every 24 hours. 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. FIGURE 2: MOUNTING HOLE FOR MOUNTING TO VISTA ENCLOSURE (No. 6x3/4 Type AB) FREEZE TROUBLE INQUIRY The module sends a freeze trouble inquiry to the detectors every four hours. 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 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. 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 EZ WALK TEST The communication loop between the module and detectors can be manually tested by putting the module and detectors into EZ Walk test mode. 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.
