FireAngel Smart RF Radio Module

*March 2022 Delivery

This wireless module is designed to be installed in a Wi-Safe 2 compatible smoke/heat alarm or Wi-Safe 2 compatible Carbon Monoxide alarm which offers an additional option for wireless connectivity (and which is not already wireless enabled).

When the wireless module is fitted into a Wi-safe 2 compatible Sprue Safety Products smoke/heat alarm or carbon monoxide alarm it enables the unit to be wirelessly interlinked with other Wi-Safe 2 enabled products.

When any of the interlinked products are triggered by smoke/heat (or carbon monoxide in the case of CO alarms), that unit will transmit messages to the other units in the network, sounding all the alarms in the system simultaneously, which means they provide the earliest warning of fire, to the maximum number of people. Any number of units from two, up to fifty alarms can be interlinked into a single network.
