WIRELESS VIBRATION DETECTOR
AND MAGNETIC CONTACT
AVD-100
avd100_en 12/10
The AVD-100 wireless vibration detector and magnetic contact is designed for operation
within the ABAX two-way wireless system. The device is supported by the ACU-100
controller with firmware version 1.06 or later and by the INTEGRA 128-WRL control
panel. This manual applies to the device with electronics version 1.2 D or later.
Owing to its advanced features of piezoelectric sensor signal processing, the vibration
detector can distinguish between the natural vibrations received from the environment, and
those caused by an attempt to force the door or window. The sensor signal is analyzed in
respect of its amplitude, duration and number of vibrations. The detector sensitivity and the
number of vibrations after which violation will be reported, are defined remotely.
The magnetic contact will signal violation after the magnet is moved
away from the reed switch, which means breaking the electric
circuit. Two reed switches are used in the detector and you can
program by radio which of them is to be active.
Explanations for Fig. 1:
1 - tamper contact, which opens when the cover is removed or
the unit is removed from its mounting surface.
2 - CR123A 3 V lithium battery, ensuring operation for approx. 3-
year period. The detector controls the battery status. When the
voltage drops to 2.6 V, the "low battery" information is sent. The
low battery signaling continues until the battery is replaced.
3 - location of the side reed switch (mounted on the other side of
the electronics board).
4 - location of the bottom reed switch (mounted on the other side
of the electronics board).
The LED is only functioning in the test mode:
−
it is lit for 80 milliseconds during polling time;
−
it is lit for 2 seconds after violation (sensing vibrations by the
vibration detector, or moving the magnet away from the reed
switch) or tamper (opening the tamper contact).
1. Installation
The device is designed for indoor installation. If the magnetic contact is used for the
protection of window or door, the detector should be mounted on the window/door frame, and
the magnet in/on the window sash or door leaf. Mounting the contact on ferromagnetic
surfaces and/or near to strong magnetic and electrical fields is not advisable, because it can
result in malfunctioning of the device.
Before you mount the detector permanently, check the level of signal received
from the detector by the ACU-100 controller or by the INTEGRA 128-WRL control
panel and, if necessary, change the place of installation so that the location is
optimal in terms of communication.
The battery should be mounted just before registering the detector into the
ABAX system.
