Fireangel RF-BW-T RF Interlink base (per wireless alarm - works with SW1-PF-T, HW1-PF-T, CW1-PF-T)

The RF base provides a wireless interlink between mains powered smoke, heat and CO alarms; it is quick to install and quick to link, ensuring greater output and savings. The base unit has been designed to transmit an RF signal, when the alarm attaches to it senses fire or CO. When another RF base receives this signal the attached alarm will also sound, eliminating the need for connection wires between each alarm.
