Edwards Signaling 283B-PL heat detector offers fixed temperature detection. If the temperature of the center disk rises to the sensor’s rated temperature, the fixed temperature element activates. This closes contacts in the sensor and transmits an alarm condition to the fire alarm control panel. The fixed temperature element is non-restorable and, when activated, the detector must be replaced.

Edwards Signaling 439D-8AW-R is an 8-inch diode polarized, vibrating bell for use with fire alarm equipment. It operates in conjunction with an installed fire alarm panel and detection devices. The steel alloy gong is red epoxy powder coated and produces a loud, resonant tone required in fire alarm systems.

Edwards Signaling 323D-10AW is a 10-inch gray single stroke bell designed for fire alarm applications. The gong is made of selected alloy steel to give the loud, resonant tones necessary in fire alarm systems.

Edwards Signaling 701U is a two-wire self-diagnostic smoke detector base.

Edwards Signaling 517THB smoke detector with 9V battery backup is designed for multi-family, residential and institutional occupancies defined by NFPA 101, in compliance with UL 217 and NFPA 72. It provides a three position test feature that simulates actual smoke conditions. The temporal pattern evacuation tone is a standard feature. It is designed for ceiling or wall mounting on a standard electrical box and can tandem wire up to 12 units (or 6 with relay) to form a system.

Edwards Signaling 302-EPM-194 is an explosion proof heat detector for installations in hazardous locations. The normally-open device is designed to close an electrical circuit upon activation. It features rate compensation and is available with 194 °F (90 °C) rating.

Edwards Signaling 277B-1110 is a non coded single action fire alarm pull station with termnals for field wiring connections. It is suitable for fire alarm installations in schools, hospitals, factories, and industrial locations. The station provides a break glass, initiating operation.

Edwards Signaling E-PDD intelligent duct detector provides early warning of an impending fire and shut down the HVAC unit in order to prevent smoke from circulating throughout the building. It features a unique design that speeds installation and simplifies maintenance. Removable dust filters, conformally coated circuit boards, and optional water-resistant gaskets keep contaminants away from components, ensuring years of trouble-free service. The duct smoke detector is designed for use in duct applications where temperatures can exceed standard detector capabilities.

Edwards Signaling E-PHD is an intelligent analogue optical/fixed temperature detector. It houses a replaceable optical sensing chamber that detects smoke, as well as a fixed-temperature sensor that detects heat. The detector analyses data from both sensors to determine when an alarm is initiated. It continuously adjust its sensitivity reference value to compensate for changes in the environment such as the presence of dirt, temperature, and humidity. The detector issues a dirty sensor warning when it reach its preset limit, reducing the chance of a nuisance alarm.

Edwards Signaling MPSR2-S45W-GE is a non coded fire alarm manual pull station. The weatherproof station is rated for outdoor use.
