Product Part No. IGSBV40xxx
4.1. General
Adaptor shape is similar to the Data-Seal enclosure with the required
modifications for cable connection. RF channels specifications are identical
to the Data-Seal.
4.2. I/O’s
The adaptor has 3 inputs and internal reed switch.
The internal reed switch is used to sense removing of the enclosure from
installation fixture. A magnet should be installed in the fixture. See figure 1 and 2
for reed switch location. NCND D4X5mm magnet is recommended. Locate a
magnet in one of reed switch ends. Each one of the three inputs can be
configured to work in digital mode or analog mode. Digital mode gives the basic
ON/OFF functionality without tamper proof of the cable. In analog mode, the
sensor ON/OFF states are sensed and cable short or disconnect are sensed as
well.
4.3. Setting Digital /Analog mode
To work in digital mode simply connect the sensing switch to the cable. To work in analog
mode connect the sensor according to Figure 3 below.
