Use this Interlock switch to render it impossible to activate the electric controls for a shutter until you have removed the Armoured Padlock from the Ground Unit and placed it into the slot in the top of the enclosure.
This can save hundreds of pounds in repair bills, allowing the safe installation of ground unit security on an electrical shutter.
PLEASE NOTE ! This unit is suitable for use with the 93mm or 73mm armoured padlocks, and is not suitable for use with the 91mm padlock.
