Est duct detector

To avoid the effects of stratification, install the sensor inlet tube a minimum of six duct widths beyond any bends in the duct. An alarm is activated when the quantity (percent obscuration) of com-bustion products in that air sample exceeds the detector’s sensitiv-ity setting. DUCT SMOKE DETECTOR , 15. Life Safety Consultants is here to ensure your fire and smoke detectors are always in working order. 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. However, the problem is the detector still remembers it was dirty. Duct Detector Dirty Memory At this time, the duct detector can be put back together. FX-PDD sensors are engineered to operate optimally under the harsh environmental conditions frequently found in HVAC ductwork. Nonetheless, before installing the detector , test the duct air velocity, temperature, and humidity to verify that it is within the operating range of the detector.

Consult the FX-PDD installation sheet for details. The SuperDuct Conventional Two-Wire Duct Smoke Detector detects the presence of smoke in a building’s HVAC system under extended temperature ranges. Its primary purpose is to provide early warning of an impending fire and to prevent smoke from circulating throughout the building.

Sample tube length must span the entire width of the air duct and the tube can be easily cut to any length. What is HVAC duct detector? Free shipping for many products!

The duct housing must be installed on ducts at least inches (200mm) wide. An air duct smoke detector is a regular photoelectric smoke detector , only set up to monitor the air in a plenum, or air duct. The way most photoelectric smoke detectors work is based on reflectivity. A Light Emitting Diode (LED) shines light into a black chamber so its light will be absorbed by the inside black walls. EDWARDS EST SIGA2-COS CARBON MONOXIDE DETECTOR.

WARNING: The carbon monoxide (CO) alarm indicates the presence of CO, which can kill you. System Sensor duct smoke detector from harsh elements. This enclosure provides protection in outdoor dripping water. CAUTION: Do not overtighten the screws. To clean the duct smoke detector: 1. Remove the detector’s cover then power down the detector by disconnecting the initiating device circuit wiring.

Using a vacuum cleaner, clean compressed air, or a soft bristle brush, remove loose dirt and debris from inside the detector housing and cover. With power source de-energized and the smoke detector not installe wire all connections per engineering drawings. Refer to the applicable figures below depending on your duct housing model number.

With all wiring in place, install the detector head. Energize the duct detector. 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. The SIGA-COD detector is compatible only with the Signature Loop Controller. They mount to European BESA and 1-gang boxes with 60.

The DNR is an Intelligent non-relay photoelectric duct smoke detector for use with ONYX Series panels. Duct detectors are not a substitute for an open area smoke detector. The DNRW is a Watertight intelligent non-relay for use with ONYX Series panels. The FSL-751DNR is an Intelligent, high sensitivity duct smoke detector for use with ONYX Series panels. The detector housing shall be UL listed per UL 268A specifically for use in air handling systems.

Smoke detectors designed for use in air duct systems are used to sense the presence of smoke in the duct. The flexible housing of the duct smoke detector fits multiple footprints from square to rectangular.
