Use one 433 MHz transmitter for a magnetic contact or garage-door tilt zone plus two normally closed external-contact zones, each with its own serial number.
Monitor an overhead garage door with a magnet-free mechanical tilt sensor, slow-loop false-signal resistance, five-year battery, and extended -22 to 120 F range.
Hide open/close protection inside a door or window frame with a compact 433 MHz recessed contact, rare-earth magnet, and flexible press-fit or screw mounting.
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.
Listen for framed-glass breakage with a 433 MHz acoustic detector, dynamic signal processing, two sensitivity levels, and up to 20 feet of tested coverage.
Combine photoelectric smoke, 135 F heat, carbon monoxide, and low-temperature reporting in one 345 MHz detector with an 85 dBA local sounder and bilingual voice alerts.
Protect multiple windows from one location with a wireless acoustic glassbreak detector offering a 25 ft maximum range, four sensitivity settings, and ten-year battery.
Reduce nuisance alarms with a wireless DUAL TEC detector that confirms motion through PIR and X-band microwave sensing, selectable pet modes, and temperature alerts.
