<br />
<br />Smoke detector shall be a System Sensor jJ Series model number~ listed to Unden-vriters Laboratories UL 268 for Fire Protection Signaling Systems. The
<br />detector shall be a photoelectric type (ModeI2W-B, 4W-B) or a combination photoelectricithermal (ModeI2WT-B, 4WT-B) with thermal sensor rated at 135"F
<br />(57.2"C). The detector shall include a mounting base for mounting to 3',I,-inch and 4-inch octagonal. single gang, and 4-inch square back boxes with a plaster
<br />ring, or cirect mount to the ceiling using drywall anchors. Wiring connections shall be made by means of SEMS screws. The detector shall allow pre-wiring of
<br />the base and the head shall be a plug-in type The detector shall have a nominal sensitivity of25 percent-per-foot nominal as measured in the UL smoke box.
<br />The detector shall be capable of automatically adjusting its sensitivity by means of drift compensation and smoothing algorithms. The detector shall provide
<br />dual coler LED indication which blinks to indicate power up, normal standby, out of sensitivity. alarm. and freeze trouble (ModeI2WT-B, 4WT-B) conditions. When
<br />used in conjunction with the 2W-MOD2 module, 2-wire models shall include a maintenance signal to indicate the need for maintenance at the alarm contrel
<br />panel, and shall provide a loop testing capability to verify the circuit without testing each detector individually.
