Description
AD 700 is a modern acoustic glass break detector giving an
alarm when glass is crossed at intruder attempts through
windows, doors and glazed walls.
The detector is based on latest micro controller computer
technology and programmed to take a lot of relevant acoustic
factors into account: the Digital Room Compensation (DRC).
This makes the detector able to differ between a true glass cross
and other irrelevant sounds.
The detector is for indoor use and can be mounted either in the
ceiling or on a wall opposite to the window being monitored. The
coverage area is 165° which means that several windows in a
single room can be protected.
The panes should measure at least 30x30 cm and maximum
600x600 cm with a maximum glass thickness of 6,5 mm.
24-hour loop
The AD 700 can be used in a 24-hour loop and will function well
in most environments. It is recommended to make tests for a
period of 3–4 weeks. However, noisy areas must be avoided like
industrial workshops, gyms and similar areas. Under very rare
conditions, it may be possible for a combination of random
sounds to trigger an alarm.
Select the best place for the detector
The detector must have a clear “line-of-sight” to the protected
glass.
At ceiling mount make sure the microphone points towards the
pane.
Mount the detector within 9 m from the glass but not closer than
1 m.
At wall mount do not set the detector closer than 30 cm from the
ceiling.
Mount the detector minimum 50 cm from the corner.
Avoid mounting the detector close to air vents.
Avoid placing the detector closer than 30 cm to edges, openings
and large objects that can reflect the sound.
