All electrical installation and maintenance must be carried out by a competent person. If in doubt,
consult a qualified electrician. Any new wiring must be carried out by qualified personnel in
accordance with the current edition of the IET Wiring Regulations (BS7671).
!
Ensure the electrical supply is isolated before making any connections or adjustments.
!
1. Select a suitable location for the unit (following the guidelines under
Positioning
) and
prepare a single-gang pattress or back box as necessary.
2.
The unit contains a battery, which must be switched on prior to use. Using e.g. a small
screwdriver, move
Switch 1
to the ‘ON’ position as indicated on the accompanying label.
3.
Adjust the controls according to the operational requirements.
− Rotate the
Timeout
and
Lux Level
thumbwheels to the desired settings. For non-
lighting loads, ensure the latter is set correctly. See
Controls
below.

Connect the wiring as shown in Figure 2 (or in any suitably appropriate form) using
mains cable having a current rating appropriate to the load.
5. Fix the unit into position with the two screws and caps supplied.
Controls
•
Timeout
(10 seconds to 60 minutes): Sets the period of time over which no motion must
be detected, after which the load is switched off.
•
Lux Level:
Sets the ambient light level threshold, below which the unit will permit
activation upon detecting motion. For non-lighting loads, and in other cases where
operation should be permitted at any light level, turn the control fully towards ‘Light’.
•
Operating Mode
WMPAD2(-L)
:
Select either
Presence Mode (‘Pres.’)
or
Absence Mode
(‘Abs.’)
. See
Operation
for details.
Additional Guidelines
• If the unit will be disconnected from the mains supply for an extended period, return
Switch 1
to the ‘OFF’ position until it is next required.
• The screw caps may be removed at a later date with the aid of an adhesive putty such
as Blu-Tack.
LED Indicator
WMPAD2-L only
The LED indicator lights when the load is off,
and the ambient light is below the threshold
set by the
Lux Level
thumbwheel. As well as aiding location of the unit in darkness (when
used in
Absence Mode
), it can be used to check that the
Lux Level
setting is appropriate.
The electrical supply to the unit MUST be isolated before making adjustments.
