GreenBrook T40S Installation & Operating Instructions Manual

light switch will fail to operate. Always
disconnect power before replacing the bulb
by pulling the fuse carrier “A” until the fuse
is fully visible. It may be necessary to replace
the fuse if the switch does not operate when
the carrier is pushed back into position
following bulb replacement. There is a slot in
the base of the carrier which allows the old
fuse to be pushed upwards and removed.
In order to ensure that the set programmes

do not overlap, it is advisable to plan
beforehand, using the table below.

e.g. First programme will be set to come on
at 8.10pm until 11.06pm everyday.

REGULATIONS

Before attempting any installation work turn off
the electrical supply at the mains switch, fuse box or
consumer unit and for additional safety remove the
fuse.
GreenBrook security wall light switches
cannot be used with other electronic products.

1. After installation, the internal back up

battery will need to be fully charged to
enable correct operation.

2. After the mains supply is switched back on,

wait 5 minutes and operate the reset
button and allow the internal battery to
charge for 45-60 minutes. After this
period follow the operating instructions
as normal.

3. DO NOT use in two-way systems with

dimmers or any other switch containing
electronic circuitry.

4. DO NOT use with fluorescent strip lights

or low energy compact fluorescent lamps.

5. DO NOT use with low voltage lighting.

6. ONLY SUITABLE for most tungsten

filament lamp loads of 40 to 400W.

7. Not suitable in 3-way circuits.

NOTE

If using a metal backbox this should be

earthed.

Before installing your Security Wall 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 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 MAINS 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 5
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.

1. If the digital display remains blank,
press the RESET button. Also, check
that the light bulb has not blown.

2. If the light switch will not switch on or off
in a one way circuit, check that the screws
which fix the security light switch to the
wall box have not been over tightened.

3. If the light will not switch on or off from
either switch in a two way circuit ­(If the above does not solve this problem)
the wiring may be incorrect, and requires
re-checking. Check that the wire
connected to the L2 terminal of the two
way switch has been removed and
reconnected to the “C” (common)
terminal. Incorrect wiring will often result
in a blown fuse. Should the switch remain
in-operative after correcting the error,
replace the fuse with the spare provided.

4. If the light operates correctly from one
switch in a two way circuit then the wiring
is incorrect. Recheck to find error.Check
that the wire connected to the L2 terminal
of the two way switch has been removed
and reconnected to the “C” (common)
terminal.

5. If the digital display goes blank when the
other switch in a two way circuit is
operated, please refer to no. 4 above.

6. If loss of time and programmes set occurs
after the replacement of either a blown
fuse, blown bulb or power failure - Press
the RESET button and reset the correct
time and day and re-programme the

required on and off times.

Every effort has been made to ensure that
the guidance information on this sheet will
enable the installation of the security light
switch to be carried out safely and correctly.

1. Ensure light fitting(s) being controlled have
bulb(s) fitted, otherwise light switch will
not function.

2. After installation is complete, reconnect
power at the mains (remembering to
replace fuse if removed for safety reasons).
The red neon “K” and the L.C.D. display
“B” will now be flashing. (Allow internal
battery to charge for 45 minutes).

To access controls, with thumb and forefinger
on either side, ease cover forward. With tip
of ballpoint pen, press reset button “J” to

Press and hold down TIME button “C”
continuously.
Press DAY button “D” until present-day is
displayed.
Press HR and MIN buttons “E” and “F” until
correct time is set using a 24-hour clock.

will stop flashing.

e.g. L.C.D.display “B” showing current time is

3.15pm on Wednesday.

NOTE

Continued pressure on any of the
DAY,HR,MIN buttons whilst TIMEbutton is
depressed will advance the display rapidly.

There are a maximum of 6 ON and 6 OFF
times available. Each ON/OFF time can be
used individually on any day(s)
throughout the week, OR can be set to
repeat on one of the following
combination of days: to run a programme,
override switch “L” must be in the auto
position.

MO TU WE TH FR SA SU (days of the week);
MO TU WE TH FR (weekdays);

Once programming is completed, the lamp
can be switched on and off at varying times
on a daily basis if RANDOM FUNCTION is
selected. Simply press DAY“D” and HR “E”
buttons simultaneously. The word TIMER will
flash to show RANDOM mode is activated. To
cancel RANDOM, press DAY “D” and HR“E”
simultaneously again and the word TIMER

Press PROG “G” and on each occasion all
previously set ON and OFF times will be
displayed. Any alterations can be made by
pressing button “D”, “E” and “F” as
appropriate. Blank ON/OFF times will have 4
dashes instead of numbers. New programmes
can be entered by following steps 1 to 8 in
example 1.

During those occasions when you are at
home early and you do not want your
security light switch to operate as
programmed, slide switch “L” so that MAN
shows for manual only operation. The pre-set
programmes are still stored. The switch can
operate only via push switch “H”. The red
neon “K” will also go out.
To recall AUTOmatic programme (i.e. to
activate switch to pre-set programmes) slide
OVERRIDE switch “L” so that AUTO shows.
Neon light “K” will come on and the light
will resume to come ON and OFF as
previously programmed.

When all settings have been completed, close
the front cover plate until it clicks into
position, concealing the operating controls.
The room light(s) can be turned ON and OFF
by simply pressing the top front cover once,
or by operating the switch at the other end
of a 2-way circuit. The position of the
override switch “H” does not affect the
operation.
With cover plate up, the red neon “K” is still
visible, enabling you to check at a glance
whether the light switch is in AUTO
(programme mode), in which case the neon
will be lit, or in MANUAL mode when it will
be off. To access the controls again, grip the
cover plate with forefinger and thumb either
side and ease cover forward.
