Add photoelectric smoke detection, 135 F heat sensing, rate-of-rise response, an 85 dB horn, and automatic drift compensation to compatible DSC 433 MHz systems.
-
Add system-connected smoke detection with a 2-wire photoelectric head, drift compensation, dual-color status LEDs, and plug-in mounting base. -
Combine photoelectric smoke sensing, 135 F heat detection, freeze trouble, and an 85 dB temporal sounder on a compatible two-wire circuit. -
Use separate power and alarm wiring with a 4-wire photoelectric smoke detector, drift compensation, removable chamber, and dual-color status LEDs. -
Equip a compatible four-wire circuit with photoelectric smoke sensing, a 135 F thermal element, freeze trouble, and an 85 dB temporal sounder. -
Use mechanical heat detection where smoke sensing is unsuitable with a 135 F fixed threshold, restorable 15 F-per-minute rate-of-rise element, and 50 x 50 ft listed spacing.
-
Protect higher-temperature spaces with a 194 F fixed threshold, restorable 15 F-per-minute rate-of-rise response, and single-circuit mechanical design.
