Modes of Operation
When using the sensor in momentary mode, it will be necessary to connect using a 4 core cable.
The N.C. alarm contacts are non-latching.
⦁
Upon alarm activation the alarm contacts will open circuit momentarily for a minimum time of 1 second
⦁
before automatically resetting.
The LED will illuminate when the alarm contacts are open circuit in response to an input signal.
⦁
⦁
LED indication: During the sensitivity test procedure indication of the green LED denotes
operation. Indication of the red LED denotes
conditions.
⦁
Dual stage linear sensitivity: The detector permits the installer a greater threshold of sensitivity adjustment
by adjustment of the potentiometer through either a low level or high level adjustment.
⦁
When DIP Switch 5 is in the ON position the sensitivity potentiometer allows adjustment in the high
sensitivity area and when in the OFF position allows adjustment in the low sensitivity area.
Installation Procedure
1.
Select the intended position for installation, ideally positioned horizontally in the vertical center of the
enclosure, 50mm to the right of the large opening.
Ensure the surface is clean and clear of any irregularities.
2.
Remove the sensor cover by unscrewing the single captive screw until the cover can easily be removed
from the base.
3.
Carefully lift the printed circuit board from the base.
4.
Position the base in the mounting position and mark the desired fixing holes (3.1mm drill).
5.
If rear cable entry is required, cables should be threaded through the rear of the base.
6.
Fix the base in position using M3 pan head machine screws to the captive nuts provided in the enclosure, or
with nuts and washers if located in an alternative position.
Take care not to let the screw protrude further than the nut height on the rear of the enclosure.
7.
Carefully push the printed circuit board onto the base.
8.
Make the electrical connections to the Shockgard SS-102, wired in series with the enclosure tamper switch
24HR monitor.
9.
If side cable entry is being used, remove the appropriate knockout from the cover and insert a grommet.
