Fire Alarm Panel Mains Keyswitch
The Fire Alarm Control Panel (FACP) Mains Keyswitch, White, (Part No. BF319) is a lockable, double-pole keyswitch that provides secure switching of the mains supply to a fire alarm panel in accordance with BS5839-1. It is ideal for use during routine test and maintenance tasks. The BF319 is normally wall mounted and fits to a standard UK 47 mm deep, single gang flush or surface mount back box. Please note, some dry lining & surface boxes may be a tight fit to this switch. It is strongly advisable that the installer check the intended combination of switch and back box. If using a 4 lug flush metal back box, bend the top and bottom lugs out of the way to avoid interference with the back of the switch.
