Firefighter's Extract Override Switch (CAS-R | FEOS)

Product features and details.
1
Product Overview

Firefighter’s Extract Override Switch (CAS-R | FEOS) allows the Fire & Rescue Service (FRS) to take control of Variable Speed Drives (VSD) controlling the Mechanical Smoke Ventilation System (MSVS) to help maintain common escape routes free of smoke and heat in Fire Fighting Mode.

They are design to operate with the Sertus Addressable Control System (CAS-R) and give clear instruction of FIRE FIGHTER USE ONLY and BOOST, AUTO, OFF mode.

Operation is by lifting the polycarbonate cover and the use of the key switch to the required position.

The central AUTO mode allows the MSVS to run automatically during Means of Escape Mode following a fire trigger, BOOST increases the extract speed by controlling the VSD in the Fan Control Panel and OFF switches the extract fan off whilst keeping the system in alarm.

The switch may be installed on any level adjacent to the zone it commands to allow local override for the FRS. All switch commands are visible at, and can be overridden by the Sertus Graphical User Interface (GUI).
