A05-0318-006 • 7/06 • #1676 Ordering Information Model Thermal Wiring Alarm Current 2W-B No 2-wire 130 mA max. limited by control panel 2WT-B Yes 2-wire 130 mA max. limited by control panel 4W-B No 4-wire 20 mA @ 12V, 23mA @ 24V 4WT-B Yes 4-wire 20 mA @ 12V, 23mA @ 24V Accessories 2W-MOD2 2-wire loop test / maintenance module RT Removal / replacement tool SENS-RDR Sensitivity reader A77-AB2 Retrofit adapter bracket, 6.6 in. (16.76cm) diameter Smoke Detector Specifications Architectural/Engineering Specifications Smoke detector shall be a System Sensor i3 Series model number_______, listed to Underwriters Laboratories UL 268 for Fire Protection Signaling Systems. The 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 135°F (57.2°C). The detector shall include a mounting base for mounting to 3½-inch and 4-inch octagonal, single gang, and 4-inch square back boxes with a plaster 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 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 detector shall be capable of automatically adjusting its sensitivity by means of drift compensation and smoothing algorithms. The detector shall provide dual color LED indication which blinks to indicate power up, normal standby, out of sensitivity, alarm, and freeze trouble (Model 2WT-B, 4WT-B) conditions. When 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 control panel, and shall provide a loop testing capability to verify the circuit without testing each detector individually.
