Protect higher-temperature spaces with a 194 F fixed threshold, restorable 15 F-per-minute rate-of-rise response, and single-circuit mechanical design.
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 heat-prone areas with a wireless detector selectable for 135 F or 200 F, 12-to-15 F-per-minute rate-of-rise detection, and 50-by-50-foot UL spacing.
Add two-zone opening flexibility with a white 345 MHz transmitter combining a built-in reed switch, closed-circuit input, included mounting hardware, and CR123A battery.
Match darker doors and trim with a brown two-zone 345 MHz transmitter featuring a magnetic contact, closed-circuit input, mounting hardware, and CR123A battery.
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.
