** New Radio Frequency Mains Heat Alarm

New Radio Frequency Heat Alarm 

Hispec are pleased to introduce our brand new radio frequency photoelectric smoke alarm. This is a combined unit where your alarm head and radio base come as one. They work off a dip switch functionality which allows them to speak wirelessly to one another, just like our old wireless bases (HSA/WB). The units come with a fast fix base which allows the installer to wire directly into the base of the unit, saving both time and maintenance costs.

This new unit will still interconnect with any existing smoke and heat alarms that are currently installed, including the HSA/PE, HSA/HE and the HSSA/PE and HSSA/HE.
