Context Plus Hush Button, XFP508X

The Context Plus Hush Button, model XFP508X, is a compact and fully monitored single-zone fire alarm control unit designed to operate directly on the Context Plus analogue addressable loop.

It is primarily intended for flats, apartments and multi-dwelling residential buildings, providing each dwelling with independently monitored fire detection, alarm and silencing facilities.

The unit allows conventional fire detectors, manual call points and sounders to be installed inside each dwelling while remaining fully connected to and monitored by the building’s main communal addressable fire alarm panel.
