System Sensor D4P120 SF 11/02 (normally open) contact devices

(normally open) contact devices

SuperDuct detectors use differential sensing to prevent gradual environmental changes from triggering false alarms

With a list operating temperature range of as low as -31°F to as high as 151°F (-35°C to 66°C)

The Hochiki DCP-FRCME-M Fast Response Contact Monitoring Modules are designed to be used with pull stations

System Sensor D4P120 SF 11/02 (normally open) contact devicesD4P120 detectors are designed to operate on 24V DC V AC or 120V AC. Alarm and supervisory relay contacts are available for control panel interface (alarm initiation), HVAC control, and other auxiliary functions. Auxiliary relays are provided for fan shut down. Detector interconnection provides signaling of up to 50 other detectors in the loop for multiple fan shut down. These detectors are not designed for 2 wire applications.
