The InnovairFlex D4120 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 senses smoke in the most challenging conditions, operating 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 (noncondensing).
Gain an even higher level of protection for facility-wide fire and life safety systems with System Sensor multi-voltage conventional relays. These relays control high-current switching applications in an overall fire protection system, such as fan and damper assemblies, doors, elevators, air handling systems and other types of system interfacing.
Whether at home, work or out on the town, building occupants are guarded by advanced detection technology designed to protect life and property from fire and other emergency situations. From smoke detectors commonly found in homes to multi-criteria models networked to a sophisticated control panel, very little occupied building space is left unprotected, or more [...]
The System Sensor high-sensitivity laser smoke detector provides enhanced fire-detection capabilities to protect mission-critical facilities where downtime or business interruption is not an option. The laser smoke detector is capable of sensitivities that are 100 times more sensitive than standard addressable or conventional smoke detectors. They are designed to respond to incipient fire conditions as [...]
Canada’s Largest Telecom Chooses Laser Duct Smoke Detectors for Very Early Warning Capabilities Bell Canada, a company that supplies innovative solutions and services, had a problem. It needed smoke detectors that would provide reliable, very early warning, to protect its telecommunications rooms. Those high-asset areas with high air flow are very sensitive. Even small traces [...]
“Necessity [is] the mother of invention,” penned playwright George Farquhar. Many fire and life safety products have come about following tragedy. Cries for change immediately following major fires have led to new laws and building code changes, and oftentimes they have served as the impetus for new technologies that better protect people and property. Then [...]
Billy Taddeo, a foreman in physical plant operations for Broward County School District’s maintenance division, is responsible for protecting more than 270,000 K-12 students and 38,000 district personnel. The Broward County School system in Florida is the nation’s largest, fully accredited school district, with 273 facilities covering more than 36 million square feet. Taddeo is NICET II (National Institute for Certification of Engineering Technologies) certified.
A primer on selection, installation and testing.
Craftsmen must coordinate efforts to properly install detectors. The proper installation of duct smoke detectors is critical to preventing the transfer of smoke and other toxic gases during a fire. Unlike standard smoke detectors that are set up by a single installer, heating/ventilation/air conditioning (HVAC)-contaminant monitors can be set up by installers of various trades, [...]
A manufacturer’s specific recommended practices must be followed when testing duct-type smoke detectors (refer to NFPA Standard 90A, Section 6.4, 2002 Edition, and NFPA Standard 72, Chapter 10, 2002 Edition). In general, all smoke detectors should be tested or inspected at least annually. This will ensure the detectors are sampling the air stream, are operative [...]
