��Smoke Detector Specifications
<br /> • `,ir�oke detector shall be a System Sensor i3 Series model number listed to Underwriters Laboratories UL 268 for Fire Protection Signahng Systems.The
<br /> detectnr shall be a photoelettric type(Model?W-B,4W-B)or a combination photoelectridthermal(Model 2WT-B,4WT-B)with thermal sensor rated at 135°F
<br /> i�7.2"C).The detector shall include a mounting base for mounting to 3v2-inch and 4-inch octagonal,single gang,and h-inch square back boxes with a plaster
<br /> nny,or direct mount to the ceiling using drywall anchors.Winng connec[ions shall be made by means of SEMS screws.The detector shal�allow pre-winng of
<br /> the�iase 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.
<br /> The detectar shall be capable oFautomatically ad�ustuig its sensitivity by means of driFt compensation and smoothing algorithms.The detector shall provide
<br /> dual color LED indication which blinks to indicate power up,nonral standby,out of sensitivity,alarm,and freeze trouble(Model�WT-B,4WT-G)conditions.When
<br /> used in conjunction with the 2W-MOD2 module,2-wire models shall indude a maintenance signal to indicate the need for maintenance ai the alaim control
<br /> panel,and shall provide a loop testing capability to verify the circuit without testing each detector individually
