The Honeywell Home 5817CBXT Wireless High-Security Transmitter is a universal contact-monitoring transmitter that can be used with household and commercial fire and burglary-initiating devices such as door/window contacts, motion and glassbreak detectors, sprinkler water flow switches, tamper switches, post indicator valves, manual pull stations and remote duct detectors. Upon activation, it emits an RF signal to a control panel, sending a burglary or fire alarm to a central station. The 5817CBXT has three unique input loops (zones). The first loop (primary loop) is supervised and typically used for high-priority alarm reporting such as commercial fire or burglary (reporting transmission every four seconds). The second loop is the built-in, normally closed reed switch used in conjunction with magnet. The third loop is another normally closed household burglary loop. All three loops may be used. A fourth (automatically enrolled) loop contains two tamper switches to protect the 5817CBXT. UL Listed for residential and commercial fire and burglary. Battery Type: CR123 Lithium. Dimensions: 1-9/16″ W x 3-1/2″ H x 1-3/16 D (40mm x 89mm x 30mm).
