Before installing your security Light switch in a
two way circuit it is first necessary to determine
which method of wiring has been used in your
home.
The primary reason for doing this is to make sure
that the security switch is wired in such a way
that has a permanent live feed at all times in
order to power the electronic timer.
1. TURN OFF THE MAIN SUPPLY.
2. Loosen the two switch plates from the wall.
3. Do NOT disconnect any wires at this stage.

4. Study the existing wiring arrangement;
compare to the 'Before' illustrations.
- if you find 3 wires at each switch
(excluding the earth wire) see diagram 3.
- if you find 5 wires at one switch and 3 wires
at the other (excluding the earth wire) see
diagram 5.
After establishing the appropriate wiring
method install the Security Light Switch as
per the corresponding 'After' illustration.
