Remember to remove the protective dust cover before
installation.
Note: The dust cover may also be used to indicate when the
unit is not operational (for example, before commissioning,
during maintenance, when disabled, etc.)
To surface mount the manual call point:
1. Fix the backbox onto the wall using 4 × M4 screws (not
supplied) and feed the zone cable through the selected
cable knockouts or through the rear of the backbox.
See Figure 1 for the location of the mounting holes.
2. Connect zone cable and relay cable (if required) to the
supplied terminal block, and then plug the terminal block
into the PCB connector on the back of the front assembly
(see Figure 2).
Use the supplied cable link to test cable continuity during
installation.
See "Wiring" below for terminal block connections and
zone cable specifications.
3. Unlock and remove the front cover, and then remove the
resettable element.
To unlock the front cover, insert the key and turn it
clockwise (two clicks), then pull the cover outwards from
the bottom to remove it (see Figure 3 and Figure 4).
To remove the resettable element, push the element up,
and then pull it out (see Figure 5).
4. Fix the front assembly to the backbox using the 2 screws
supplied with the unit (located in the backbox).
5. Replace the resettable element (or add the breakable
element, if required), and then replace the front cover (see
Figure 6).
Turn the key anticlockwise (two clicks) to lock the cover,
and then remove the key.
Finally, test the manual call point (see "Testing" on page 3).
