(-L3) Smoke Detector Specifications <br />Smoke detector shall be a System Sensor i3 Series model number listed to Underwriters Laboratories UL 268 for Fire Protection Signaling Systems.The <br />detector shall be a photoelectric type (Model 2W-B, 4W-B) or a combination photoelectric/thermal (Model 2WT-B, 4WT-B) with thermal sensor rated at 1357 <br />(57.2°C).The detector shall include a mounting base for mounting to 31/2-inch and 4-inch octagonal, single -gang, and 4-inch square back boxes with a plaster <br />ring, or direct mount to the ceiling using drywall anchors. Wiring connections shall be made by means of SEMS screws. The detector shall allow pre -wiring of the <br />base and the head shall be a plug-in type. The detector shall have a nominal sensitivity of 2.5 percent -per -foot nominal as measured in the UL smoke box. The <br />detector shall be capable of automatically adjusting its sensitivity by means of drift compensation and smoothing algorithms. The detector shall provide dual - <br />color LED indication that blinks to indicate power up, normal standby, out of sensitivity, alarm, and freeze trouble (Model 2WT-B, 4WT-B) conditions. When used <br />in conjunction with the 2W-MOD2 module, 2-wire models shall include a maintenance signal to indicate the need for maintenance at the alarm control panel <br />and shall provide a loop testing capability to verify the circuit without testing each detector individually. <br />Operating Voltage Nominal: 12/24V non -polarized <br />Minimum: 8.5 V <br />Maximum: 35 V <br />Maximum Ripple Voltage <br />30% peak to peak of applied voltage <br />Standby Current <br />2-wire: 50 NA maximum average; 4-wire: 50 NA maximum average <br />Maximum Alarm Current <br />2-wire: 130 mA limited by control panel; 4-wire: 20 mA @12 V, 23 mA @ 24 V <br />Peak Standby Current <br />2-wire: 100 uA; 4-wire: n/a <br />Alarm Contact Ratings <br />2-wire: n/a; 4-wire: 0.5 A @ 30 V AC/DC <br />Physical Specifications <br />Dimensions (including base) <br />5.3 inches (127 mm) diameter; 2.0 inches (51 mm) height <br />Weight <br />6.3 oz (178 g) <br />Operating Temperature Range <br />2W-B and 4W-B: 32°F to 1207 (0°C to 49°C); 2WT-B and 4WT-B: 327 to 1007 (0°C to 37.8°C) <br />Operating Humidity Range <br />0 to 95% RH non -condensing <br />Thermal Sensor <br />1357 (57.2°C) fixed <br />Freeze Trouble <br />2WT-B and 4WT-B only:417 (5°C) <br />Sensitivity <br />2.50/o/ft nominal <br />Input Terminals <br />14 to 22 AWG <br />Mounting <br />LED Modes <br />3'/2-inch octagonal back box <br />4-inch octagonal back box <br />Single -gang back box <br />4-inch square back box with a plaster ring <br />Direct mount to ceiling <br />Power -Up Sequence for LED Indication <br />LED Mode Green LED <br />Red LED Condition Duration <br />Power up Blink every 10 seconds Blink every 10 seconds Initial LED status indication 80 seconds <br />Normal (standby) Blink every 5 seconds off <br />Out of sensitivity off <br />Blink every 5 seconds <br />Freeze trouble off <br />Blink every 10 seconds <br />Alarm off <br />Solid <br />Ordering Information <br />Model Thermal <br />2W-B No <br />Wiring Alarm Current <br />2-wire 130 mA max. limited by control panel <br />2WT-B Yes <br />2-wire 130 mA max. limited by control panel <br />4W-B No <br />4-wire 20 mA @ 12 V, 23 mA @ 24 V <br />4WT-B Yes <br />4-wire 20 mA @ 12 V, 23 mA @ 24 V <br />Accessories <br />2W-MOD2 2-wire loop test / maintenance module RT Removal / replacement tool <br />SENS-RDR Sensitivity reader A77-AB2 Retrofit adapter bracket, 6.6 inch (16.76 cm) diameter <br />f_ SY TE� <br />�/ <br />SENSOR <br />m2cha System Sensor. <br />3825 Ohio Avenue • St. Charles, L 60174 Product specifications subjec[to009 System Sensotice.Vsit rystemsensoccom for <br />Phone:800-SENSOR2•Fax:630-377-6495 urrentproductinformat5-03180i7-6/09latest version okhisdata sheet. <br />A06-0318-007.6/09•#2169 <br />
