(-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 /> Electrical Specifications <br /> Operating Voltage Nominal: 12/24V non-polarized <br /> Minimum: 8.5 V <br /> Maximum:35 V <br /> Maximum Ripple Voltage 30%peak to peak of applied voltage <br /> Standby Current 2-wire:50 NA maximum average;4-wire:50 NA maximum average <br /> Maximum Alarm Current 2-wire:130 mA limited by control panel;4-wire:20 mA @12 V,23 mA @ 24 V <br /> Peak Standby Current 2-wire:100 uA;4-wire:n/a <br /> Alarm Contact Ratings 2-wire:n/a;4-wire:0.5 A @ 30 V AC/DC <br /> Physical Specifications <br /> Dimensions(including base) 5.3 inches(127 mm)diameter;2.0 inches(51 mm)height <br /> Weight 6.3 oz(178 g) <br /> Operating Temperature Range 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 0 to 95%RH non-condensing <br /> Thermal Sensor 1357(57.2°C)fixed <br /> Freeze Trouble 2WT-B and 4WT-B only:417(5°C) <br /> Sensitivity 2.50/o/ft nominal <br /> Input Terminals 14 to 22 AWG <br /> Mounting 3'/2-inch octagonal back box <br /> 4-inch octagonal back box <br /> Single-gang back box <br /> flinch square back box with a plaster ring <br /> Direct mount to ceiling <br /> LED Modes Power-Up Sequence for LED Indication <br /> LED Mode Green LED 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 Blink every 5 seconds <br /> Freeze trouble off Blink every 10 seconds <br /> Alarm off Solid <br /> Ordering Information <br /> 2W-B No 2-wire 130 mA max.limited by control panel <br /> Yes -wire 130 mA max.limited IDy control pane <br /> 4W-B No 4-wire 20 mA @ 12 V,23 mA @ 24 V <br /> 4WT-B Yes 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� m2cha system Sensor. <br /> �/ 3825 Ohio Avenue•St.Charles, L 60174 Product specifications subjec[to009 System Sensotice.Vsit rystemsensoccom for <br /> SENSOR Phone:800-SENSOR2•Fax:630-377-6495 urrentproductinformat5-03180i7-6/09 latest version okhis data sheet. <br /> A06-0318-007.6/09•#2169 <br />
