2.
If you choose not to use the tamper switch, fasten the wire to the terminal farther from the
opening, as shown below.
•
For use in closed-circuit alarm systems.
•
Pure silver contacts ensure reliable and
long-term operation.
•
Ideal for protecting glass windows,
showcases, solid walls, ceilings, safes,
cabinets, motorcycles, skylights, etc.
•
Small size and for discreet installation.
•
Built-in tamper switch provides enhanced
security.
•
Adjustable contact pressure for different
surfaces.
•
Detects a vibration/shock on protected
surface and activates an alarm.
1.
Remove the cover and connect one lead of the wire from the N.C. input of the alarm to the
terminal of the
SS-040Q
near the opening. Connect the other lead to the terminal of the
tamper switch, as shown below.
The
SS-040Q
will trigger the alarm whenever it is vibrated
,
shaken
,
or its cover is removed.
The alarm will trigger only when the
SS-040Q
is vibrated or shaken
.
NOTE:
When protecting windows the preferred installation method is to mount the
SS-040Q
on the frame of the glass window rather than directly on the glass. This reduces the
chance of false alarms resulting from heavy vehicles passing by or from inadvertent
tapping on the window by pedestrians.

HOW TO ADJUST THE SENSITIVITY
Contact pressure below 5 grams is not recommended, as erratic operation may result and
cause false alarms. Contact pressure above 25 grams is not recommended because (a) it may
permanently damage the vibration blade; (b) the detector may not be sensitive enough to
detect vibration. This depends on the location where the detector is installed. If installed on a
ceiling the pressure must be increased. Because the internal weight faces downwards, this
reduces the pressure that is applied.
As the
SS-040Q
can be used surfaces of different materials which transfer different amounts
of pressure from the same vibration/shock, it may be necessary to adjust the sensitivity.
Turning the adjustment screw (a) in a clockwise direction makes the contact less sensitive, (b)
in a counterclockwise direction makes the contact more sensitive. Proper adjustment may be
necessary to avoid false alarms or non-activation of the alarm.
To adjust the pressure if a Gram Meter is not available, please do the following:
1.
Determine the initial contact point of the vibration detector. This is done by rotating the
adjustment screw in a clockwise direction until the contact points just touch. At this point the
pressure is usually approx. 1 gram. (An ohm meter placed across the terminals will show
exactly when initial contact is made.)
2.
After contact, turn the adjustment screw past the contact point (a) 45 degrees to obtain
approximately 6 grams, (b) 90 degrees to obtain approximately 11 grams, (c) 135 degrees
to obtain approximately 16 grams, etc. to obtain the sensitivity you require. Please use
figure 1 shown below.
