2. Installation Requirements
The SD1+ has been designed to be connected to an intruder alarm control panel or
similar. The control panel must have an auxiliary power output of between 11.5V and 14V,
and the ability to provide a minimum of 100mA.
The unit is supplied with a 2 metre telephone lead which will plug directly into any standard
BT socket and it is therefore recommended that the unit is sited as near to a BT telephone
socket as possible. If this it not possible an approved BT extension lead may be required or
the unit can be hard wired to the BT. socket (see section 8).
3. Mounting Instructions
1. Separate the cover from the base by using a screwdriver to push two of the retaining
clips (top or bottom) inwards from the base indents. Remove cover assembly and
store in a safe place.
2. Hold the base in position (keyhole to the top) and mark the three securing holes.
Remove the base then drill and plug the holes.
3. Pass all cables into the base through the cable entries and then secure the base to
wall.
