Alarmtech CD 475 Installation Manual And Datasheet

DATASHEET AND INSTALLATION MANUAL

DESCRIPTION

CD 475 offers reliable monitoring against attacks with me-
chanical tools. The CD 475 is a chock- and vibration detec-
tor with 3 separate detection channels: an integration
channel / saw channel for weak signals with long duration,
a counting channel that senses strong impact on the mon-
itored surface and an explosion channel which senses very
strong signals from e.g. an explosion.
CD 475 shares the design with CD 470 but must be con-
nected to analyzer IU 400 for alarm indication since it lacks
built-in relay outputs. In the event of an alarm, the power
consumption in the detector increases, this is detected by
the analyzer IU400 which will indicate the different
alarms.
CD 475 polarity independent, just like CD 470.

OPERATING PRINCIPLE

The CD 475 uses a piezoelectric sensor to monitor the vibration
signature of the mounting surface that occurs when it is crushed
or cut with tools. The signal has a special signature with a broad
spectrum and high amplitude that the electronics detects, then
generates a current increase and illuminates the LED. The CD 475
has a built-in self-control and voltage monitoring. Fault is indi-
cated by a flashing LED and a pulsating current increase. The in-
dication is controlled by a DAY and NIGHT function. With 8Vdc
on the power input, DAY mode is active and LED lights up at
alarm and with pulsating shine in case of failure. At 6Vdc, NIGHT
mode is active and LED is switched off in case of alarm or error.
Resetting the detector after alarm can be done in two different
ways:

Disconnect power to the detector

Switch from DAY to NIGHT mode

MOUNTING

1. Loosen the screw for the cover and lift it off.
2. Select the mounting location and mark the mounting holes
with the bottom part as a template.
3. Drill with a 2-2.5 mm drill for the two supplied mounting
screws.
NOTE! A clean and smooth mounting surface under the
detector provides maximum range.

CONNECTIONS

The detector has 2 screw terminals:
