System Sensor 1451 Ionization Smoke Detector FST-951H-IV 4-wire smoke detectors

4-wire smoke detectors

Includes a built-in 135°F (57°C) fixed-temperature thermal device

the MCS-ACCLIMATE2F sensor has a microprocessor in the sensor head that processes alarm data

these detectors are designed to provide open area protection and to be used with compatible UL-listed control panels only

upon command from the loop controller

System Sensor 1451 Ionization Smoke Detector FST-951H-IV 4-wire smoke detectorsThe System Sensor 400 Series plug in ionization smoke detectors respond quickly to both fast flaming and slow smoldering fires as required by UL 268. Unipolar dual chamber sensor has the sensitivity needed to quickly detect smoke, and the stability needed to avoid false alarms.
