2) Call Point Location and Mounting
The location of the call point should enable ease of
access for operation and testing. The unit should
be mounted using the 4 off fixing holes which will
accept up to M4 sized fixings.

To gain access to the mounting holes in the base
the front cover must be removed.
This is achieved by removing the 4 off M4 cap
head bolts holding on the cover.
Once the screws are removed the cover will hang
down out of the way to gain access to the Ex e
terminal block, the internal earth terminal and
mounting hole recesses.

3) Earthing
The unit has an internal earth terminal.
It is recommended that a cable crimp lug is used
on the earth wires.
The internal earth wire is placed under a earth
clamp which will stop the cable twisting. This is
secured by an M4 screw and spring washer.

5) Testing unit operation
The break glass unit can be tested without the
need to break/replace the frangible glass element.
A test key (7mm Allen key) is used to mechanically
drop the glass down activating the switch.
The test key is inserted in the test cam and rotated
clockwise by an angle of 60º the glass element will
visibly drop down in the viewable window.
The call point switch will now change over its
contacts to operate the alarm.
Once testing is complete the unit needs to be
reset, the test key is rotated back anticlockwise by
an angle of 60º back to its original position. The
glass element should now raise up so it is level
again in the viewable window.
