Installation
The TG123SK is ceiling mounted and gives an
approx. 5m diameter coverage at a ceiling
height of 2.4m. At 3m ceiling height the floor
level coverage is approx. 7m diameter.
Choose a ceiling position where an intruder
would be most likely to pass under.
Using the scale template (fig 4) mark out 4
holes at the position marked . These should
be positioned to ensure that the infra-red
sensor is pointing towards the main entrance
door for ease of arming and disarming.
Fit the plugs (if necessary) and screws supplied,
leave the screw heads 3mm proud of the ceiling.
Offer up the main unit so that the screw heads
fit into the large areas on the keyhole fixings
then slide the unit sideways so that the screw
heads reach the ends of the narrow areas of the
keyhole fixings.
