Simplex duct detector

Beam Detectors are used to provide “open area” smoke detection in situations where it is either impractical or not cost effective to use traditional point-type detectors or aspirating smoke detection. Sampling tubes are installed into the duct allowing air to be directed to the smoke detector mounted in the housing. This type of duct detector is intended to monitor air conditioning or ventilation ducts for the presence of smoke. TrueAlarm Analogue Addressable Detectors TrueAlarm duct sampling units detect the presence of smoke in air conditioning or ventilation ducts. Simplex recommends measurements of air flow and examination of engineering specifications that define expected duct air velocities under all conditions.

All freight and handling charges are the responsibilities of buyer, in both directions. Simplex RJ85A Steel Mechanical Ratchet Jack, Ton Capacity with Stroke offer from $399.

For this reason, both the IMC and NFPA allow duct smoke detectors to initiate a supervisory signal rather than an alarm signal. Do not install detectors on a ceiling within inches (cm) of a wall.

Duct detectors located on the return side and upstream of any filters or introduction of outside air detect smoke coming from an air conditioned space. Check Out Simplex Duct Detector On eBay. Compatible for use with Simplex Fire Alarm Control Panels that provide conventional 4-wire IDCs (initiating device circuits). Simplex compact air duct smoke sensor housings provide TrueAlarm operation for the detection of smoke in air conditioning or ventilating ducts. The Edwards SuperDuct Signature Series smoke detector is the most advanced and most reliable device in its class.

Designed for easy installation and superb reliability, SuperDuct represents the perfect balance of practical design and advanced technology. SuperDuct detectors feature a unique design that speeds installation and simplifies maintenance. This duct detector will do nothing without being connected to a MAPNET II or IDNet SLC.

The difference is that a standard smoke detector makes the decision to go into alarm locally in the detector. In Truealarm sensors the decisions are made in the panel and transmitted to the sensor. Smoke detectors designed for use in air duct systems are used to sense the presence of smoke in the duct. Mouse over image to zoom.

The picture of opened box unit is going to be listed separately on a different auction. MOUNTING THE DETECTOR. The sampling tubes may be ordered to a desired length or ordered in one of standard lengths and cut per requirements. The intake sampling tube consists of a piece of steel piping with a series of holes drilled the entire length of the tube and should extend the entire width of the duct. Locate the Panel Initiating Device Circuit (IDC) part number in the top row.

Wait two minutes for the duct smoke detector to alarm. If the duct smoke detector alarms, air is flowing through the detector. Remove the duct smoke detector cover and blow out the residual aerosol smoke from the chamber and reset the duct smoke detector.

Use duct tape to seal the aerosol smoke entry hole. One unit can accommodate multiple installation footprints to overcome mounting constraints. Tool-free, plug-in sampling tubes speed and simplify installation.
