4. Wiring / Contacts
•
Terminal connection 1 is the power 10 to 30V DC + line on both units.
Terminal connection 2 is the power 10 to 30V DC - line on both units.
The power lines need to be connected to these terminals.
•
Terminal connections 6 and 7 form a tamper output ; they are connected through a dry contact relay.
When the cover is taken off, there is no contact.
No wires need to be connected to these terminals.
•
On the receiver, terminal 3 is normally connected to terminal 4 and in the event of detection, contact with terminal
4 is broken and contact with terminal 5 is established.
It depends on how your control panel works if you need to connect either terminals 3 and 4 or terminals 3 and 5 to
the control panel.

5. How to Install the Device
•
Unscrew the attachment screw at the bottom of the cover and lift it off the rest of the unit.
•
When the cover is off, unscrew the attachment screw at the bottom of the main part of the unit (holding the
mounting plate) and remove the mounting plate by sliding it downwards.
•
If the wiring comes out of the mounting wall, break through the rubber grommet on the mounting plate, pull the
wire through and fix the mounting plate to the wall using 2 of the provided tapping screws. Make sure to seal any
gap between the wires and the grommet.
•
If the wiring is 'exposed' (i.e. on the wall), fix the mounting plate on the wall at the desired location, break the
knockouts at the left side on the back of the main unit (upper or lower ones, depending on where the wiring
comes from) and place the wiring in the knocked out openings.
•
Pull the wiring through the housing (at the top right, seen from the back), attach the wires to the correct terminals,
and fix the unit to the mounting plate.
•
Adjust alignment of the units (see “
6. Alignment
” on p. 3), check the operation and put the cover back on.
No sealing is required since the housing is designed to be waterproof.
