Product Description

4 Wire Photoelectric Duct Smoke Detector

 

Product Description

The 4-wire photoelectric duct smoke detector features a pivoting housing that fits both square and rectangular footprints and mounts to round or rectangular ductwork. This unit operates in airflow speeds of 100 to 4,000 feet per minute, temperatures of -4°F to 158°F, and a humidity range of 0 to 95 percent (non-condensing).

 

A plug-in sensor head offers improved false alarm immunity and simple installation, testing, and maintenance. An improved cover design isolates the sensor head from the low-flow feature for simple maintenance.

The detector housing provides ample wiring space, a ¾-inch conduit knockout, and built-in short-circuit protection to prevent damage to sensitive components during installation. High-contrast terminal designations make wiring easy. With its 2:1 sensor-to-power capability, the power board of the detector may be used to monitor a second sensor, D4S, simultaneously (i.e., supply and return side).

 

As many as 50 detectors can be interconnected. When one unit senses smoke, all interconnected detectors will switch their relays; only the detector sensing smoke will go into alarm, enabling the fire location to be pinpointed.

An easy-access Test/Reset button makes it possible to test the unit with the cover on. Three DIP switches can be used to configure field-selectable settings: cover tamper delay, number of sensors to be controlled, and shut down on trouble option. Each power board has two LEDs that can be used to indicate the status of connected sensors, and a quick reference imprinted on the cover explains the LED status indications (Standby, Maintenance, Trouble, and Alarm).
