MOUNTING
Note:
The ISEC
-
GLASSBREAK may be mounted in any po-
sition with no degradation in performance. However, for refer-
ence purposes in this text, the unit will be considered oriented
with the antenna at the right, as shown above.
The detector mounts with two #6 screws (supplied). The rear
case may be used as a template to mark mounting holes on
the wall.
The sensor must be in direct line of sight of all windows being
protected. Reliable detection cannot be expected around cor-
ners, in other rooms, etc. For optimum false
-
alarm immunity,
avoid installing the unit
•
in rooms with lined, insulating, or sound
-
deadening
drapes;
•
in rooms with closed wooden window shutters inside;
•
in rooms smaller than 10' x 10' (3m x 3m), and in rooms
with multiple sounds, such as kitchens, glass booths,
noisy areas, garages, etc.
•
within 4' (1.2m) of noise sources such as televisions,
speakers, sinks, doors, etc.
•
on ceilings higher than 15' (4.5m), if mounting on ceiling;
•
on 24
-
hour loop applications (perimeter loop okay);
•
where white noise (such as air compressor noise) is pre-
sent (may cause false alarms by saturating glass
-
break
frequency spectrum).
Wall Mounting
Since the sound of breaking glass travels outward from the
source, the best location for the ISEC
-
GLASSBREAK detector
is on the wall opposite the windows being protected
(assuming, of course, that the wall is within the sensor's
range). Detection is reduced with same
-
wall mounting since
such detection is partially dependent upon sound reflected off
the opposite wall.
Ceiling Mounting
Similarly, a ceiling
-
mounted sensor will detect better if mount-
ed 6' to 10'
(2
—
3
m) away from the glass, rather than directly
above it. Mount the detector on any type of ceiling in direct
line of sight of the windows being protected, at least 1' (0.3m)
and preferably 3' (1m) from the glass. See Fig. 3.
Installation Notes
1.
The unit is designed to detect the shattering of framed
glass mounted in an outside wall. Testing the sensor with
unframed glass, broken bottles, etc. may not trip the sen-
sor. The unit typically does not trip to glass
-
break tests in
the middle of a room, as such breaks are false alarms.
2.
False alarms are most likely to occur when installed on a
24
