Description

The System Sensor 1151 ionization detector uses state-of-the-art sensing chambers. Also, the System Sensor 1151 detector is designed to provide open area protection and to be used with compatible UL-listed control panels only. The capability of plugging this detector into a variety of special bases makes it more versatile than equivalent direct-wired models.

Besides, two LEDs on each detector light provide a local 360° visible alarm indication. Remote LED annunciator capability is available as an optional accessory. This detector also has the latching alarm feature. In addition, the alarm can be reset only by a momentary power interruption. For testing, this detector has an internal magnetically activated reed switch.

All bases are provided with screw terminals for power, ground, remote annunciator connections, and relay contact connections, if applicable. The electrical ratings for each detector-base combination are also include in the base installation instructions. System Sensor has available a variety of detector bases for this smoke detector, including 2-wire applications with and without relays and/or current limiting resistors, 4-wire and 120 VAC applications.
