If the mains wires are being brought along the surface:
(a) position the mounting plate so the cable trunking is as
shown in Figure 4.
(b) the mounting plate has a removable section, take it out to
interface directly with 25 mm conduit as shown in Figure 5.If
interfacing to 16 mm conduit carefully cut around the marked
section, leaving the top intact and replace the section. (If you
are not using surface wiring, the removable section must be
left in place for electrical safety reasons).
There are two other positions which are also suitable for the
surface wiring to enter (and exit) the alarm, one next to the
removable section and another directly opposite.
5. Carefully align the mounting plate and screw into place.
Connect the wires to the terminal block.With recessed wiring,
ensure the rear gasket seals around the edge of the hole in
the ceiling or wall.This is to prevent air draughts affecting the
smoke/heat entering the alarm. If the hole is too large or the
alarm does not seal it, it should be sealed with silicone rubber
or equivalent.
6. Replace the wiring cover. Check the alarm battery is
connected (Ei141/144/146 only).
7. Carefully line up the unit on the base and slide on.
8. Press and hold the test/hush button for 10 seconds. The
horn will sound. Check that any interconnected alarms also
sound within this period.
9. Connect the mains power to the alarm circuit. Check the
green light is on.
10. Attach the ‘Smoke Alarm’ identification label provided to
the distribution board to identify the alarm circuit.
11. Attach the ‘Mains Smoke / Heat Alarms’ label provided on
or near the distribution board and write in date installed and
the number of alarms on the circuit.
Ensure the alarm operates correctly - see “TESTING &
MAINTAINING YOUR ALARM” section on page 4 of the
USER INSTRUCTIONS.
