| C O N V E N T I O N A L D E T E C T I O N Series 2-Wire Loop Test/ Maintenance Module Models Available 2W-MOD2 2-wire loop test/maintenance module for 2-wire i3 series standard, sounder, and Form C relay models (Replaces Model No. 2W-MOD) Product Overview Allows all 2-wire i3TM detectors to be used on any compatible 2- or 4-wire fire alarm control panel Interprets the i3 remote maintenance signal Provides visual indication and an output relay when a detector on the loop requires cleaning Initiates the EZ Walk loop test Provides Style D wiring on IDC loops Green, red, and yellow LEDs indicate - Loop communication status - Maintenance alert - Freeze trouble - Alarm - EZ Walk test enabled - Wiring fault System Sensor's 2W-MOD2 two-wire loop test/maintenance module maximizes the benefits of the i3TM series smoke detectors, by offering detector remote maintenance signaling and EZ Walk loop testing capabilities. Installation ease. The 2W-MOD2 mounts to a 4-square back box for quick and easy installation. Terminal blocks with durable SEMS screws assure a reliable connection. Intelligence. The 2W-MOD2 allows communication to 2-wire i3 detectors with any listed fire alarm control panel. This in turn enables i3 detectors to initiate a remote maintenance signal when they are in need of cleaning, and to provide a visual indication of this condition at the module and at the panel. The 2WMOD2 also features the EZ Walk loop test for 2-wire i3 series detectors. This function verifies the entire initiating loop wiring with just the press of a button. Instant inspection. The 2W-MOD2 includes three LEDs -- green, red, and yellow -- that provide status indication for the loop. These LEDs indicate the following: - Loop communication status - Maintenance alert - Alarm - Freeze trouble - EZ Walk test enabled - Wiring fault APPROVED S3705 3015195 4-03-E 7300-1209 Architect/Engineer Specifications Loop test/maintenance module shall be a System Sensor i3 series model number 2W-MOD2, listed to Underwriters Laboratories UL 864 for Control Units for Fire Protection Signaling Systems. The module shall include provisions for mounting to 4-inch square back boxes. Electrical Specifications Operating Nominal: Min.: Max.: Voltage 12/24 V 8.5 V power limited 30 V power limited Maximum Standby Current 30 mA Maximum Alarm Current 90 mA Maximum Maintenance Current 53 mA Alarm Contact Ratings 0.5 A @ 36VDC, Resistive Maintenance Contact Ratings 2 A @ 30VDC, Resistive Wiring connections shall be made by means of SEMS screws. The module shall provide three LED indicators which will blink or illuminate to indicate communication status, maintenance alert, alarm or freeze trouble conditions, and EZ Walk loop test mode. The module shall allow communication to 2-wire i3 detectors with any UL listed fire alarm control panel. The 2W-MOD2 shall offer provisions for Style D wiring on IDC loops, and shall provide a loop testing capability to verify the initiating loop wiring. Maximum Ripple Voltage 30% of applied voltage (peak to peak) LED Modes LED Color Green LED Status On Blinking 1 sec. on / 1 sec. off Off Red LED Yellow LED On Blinking 1 sec. on / 1 sec. off On Blinking 0.5 sec. on / 0.5 sec. off Condition Power on. Detectors on loop do not have communication capability. Power on. Detectors on loop are communicating normally. Power not applied or module not in operation. Detector on loop in alarm. One or more detector on loop is in need of maintenance or is in freeze trouble. Loop wiring fault exists. EZ Walk test mode. Power Up Sequence for LED Indication Condition Initial LED status indication EZ Walk test available Duration 2 minutes 6 minutes after reset Physical Specifications Operating Temperature Range 14F-122F (-10C to 50C) Operating Humidity Range 0 to 95% RH non-condensing Input Terminals 14-22 AWG Dimensions Height: 4.5 inches (114 mm) Width: 4.0 inches (101 mm) Depth: 1.25 inches (32 mm) Weight 8 oz. (225 grams) Mounting 4-inch square back box Ordering Information Model 2W-MOD2 Description 2-wire loop test/maintenance module for 2-wire i3 series standard, sounder, and Form C relay smoke detectors System Sensor Sales and Service System Sensor Headquarters 3825 Ohio Avenue St. Charles, IL 60174 Ph: 800/SENSOR2 Fx: 630/377-6495 www.systemsensor.com System Sensor Canada Ph: 905.812.0767 Fx: 905.812.0771 System Sensor Europe Ph: 44.1403.276500 Fx: 44.1403.276501 System Sensor in China Ph: 86.29.8832.0119 Fx: 86.29.8832.5110 System Sensor in Singapore Ph: 65.6273.2230 Fx: 65.6273.2610 System Sensor - Far East Ph: 85.22.191.9003 Fx: 85.22.736.6580 System Sensor - Australia Ph: 613.54.281.142 Fx: 613.54.281.172 System Sensor - India Ph: 91.124.637.1770 x.2700 Fx: 91.124.637.3118 System Sensor - Russia Ph: 70.95.937.7982 Fx: 70.95.937.7983 (c) 2003 System Sensor.
