The System Sensor Model D2 Duct Smoke Detector utilizes photoelectric technology for the detection of smoke. This detection method, when combined with an efficient housing design, samples air passing through the duct allowing detection of a developing hazardous condition. When sufficient smoke is sensed, an alarm signal is initiated and appropriate action can be taken to shut off fans, blowers, change over air handling systems, etc. These actions can facilitate the management of toxic smoke and fire gases throughout the areas served by the duct system.

System Sensor® SSM Series alarm bells are low-current, high-decibel notification appliances for use in fire and burglary systems or other signaling applications. They come pre-wired to reduce installation time, and also incorporate a polarized electrical design for use with supervision circuitry. With reliable performance, SSM Series alarm bells provide loud, resonant tones. They operate on 24 VDC and are motor driven.

The DST family of sampling tubes are pieces of steel piping with a series of holes drilled the entire length of the tube and should extend the entire width of the duct. The correct length has to be chosen for width of the duct where it will be installed. The sampling tube length must extend at least 5/8 across the duct width for optimal performance. The sampling tube is always installed with the air inlet holes facing into the air flow. The tubes lock securely into place and can be removed by releasing the front or rear locking tab.

The System Sensor LENS-A2 is an amber lens that can be used for any indoor wall-mountable strobe. L-Series color lenses come in four colors options including amber, blue, green and red. The lenses are compatible with L-Series strobes including wall or ceiling mount. Note that color lenses must only be used with devices that are not fire printed.

The System Sensor LENS-AC2 is an amber lens that can be used for any indoor wall-mountable strobe. L-Series color lenses come in four colors options including amber, blue, green and red. The lenses are compatible with L-Series strobes including wall or ceiling mount. Note that color lenses must only be used with devices that are not fire printed.

SENS-RDR sensitivity readers are battery-powered devices equipped with an infrared optical interface for automatically reading data sent by smoke detectors every 10 seconds. They decode the sensitivity and status data and show the information on their LCD displays. The sensitivity reader may be used either as a handheld device or with a standard threaded extension pole.

SSV Series alarm bells are low-current, high decibel notification appliances for use in fire and burglary systems or other signaling applications. These units operate on 120V AC (utilizing a vibrating mechanism) and are pre-wired to reduce installation time.

The SWIFT Wall AV Bases are intended for use with compatible System Sensor L-Series AV notification appliances to meet a comprehensive range of notification requirements. The AV Base provides power for the audio and visual signals and supports wireless communication with the Fire Alarm Control Panel (FACP). The L-Series AV notification appliance is mounted directly to the wireless AV base allowing flexibility in color, placement and signal output. Power is supplied through two sets of 4 batteries – one set provides power for wireless communication, and the other set provides power for the notification appliance’s audio and/or visual signal. Battery life of the wireless portion is UL listed for at least 2 years. Battery life for the AV set of batteries depends upon the activation time and output level of the audio or visual signal. The AV base boosts output voltage to support 24VDC options on connected devices.

System Sensor L-Series LED color LENS-R3 lenses come in four colors options: amber, blue, green, and red. The lenses are compatible with L-Series strobes including wall- or ceiling-mount. These color lenses must only be used with devices that are non-fire printed.
