The Logifire wireless repeater is a wireless range extender designed to increase the distance between the 45TRA100 or 45TRC100 expanders and Logifire wireless devices. Multiple repeater modules can be connected to each wireless gateway in the system, allowing you to build large, fully wireless fire alarm installations or to add wireless devices in areas where cabling is difficult. Thanks to the Logifire wireless repeater, the total distance between the devices and the gateway module can reach up to 3 km in open areas. Each Logifire wireless repeater includes a built-in EN54 power supply and space for a back-up battery (Comelit Art. 30076004.5), designed to provide up to 72 hours of operation. Dimensions: 191×125×60mm. Certified according to EN54-4, EN54-18, and EN54-25.
