Architect/Engineer 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 combination photoelectric/thermal
equipped with a sounder (model 2WTA-B, 4WTA-B), a Form C relay (model
2WTR-B), a combination sounder/relay (model 4WTAR-B) or an isolated
thermal/sounder/relay (model 4WITAR-B). 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% 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 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. When used in conjunction with the RRS-MOD module,
all i3 sounder models on a loop shall sound when one alarms, all shall be
synchronized, and all sounders may be silenced from the panel.
