The terminals of [Tmpout] are connected with the
COM
and
NO
contact of a relay.
As long as this relay is active, both contacts will be closed. The status of this relay is also
determined through the MCU (Micro Controller Unit).
The MCU has as tamper related inputs:
- 2 permanent inputs: a) Internal tamper from the side hatch of the HY-3 pack, and
b) the internal tamper spring on the back cover.
- 1 input from the tamper wire in the cable coming from an eventual connected Control-
Box. This tamper cable will only be “seen” if a Control- Box is really connected and
the “Control Box = present” is set.
- 1 input from a programmable input eventual set as tamper input. See p. 18.
Based on the info of these different inputs, the MCU software will decide whether to activate
or not to activate the [Tmpout]-relay.
Properties of the tamper mode:
- The [Tmpout] relay is in rest position (Ta and Tb open).
- The moment a tamper mode starts or ends is kept in the log, together with which tamper
contact or tamper input has caused this tamper mode.
- Only if:
a) Only if the click on option’
R
Tamper mode can start alarm mode’ is clicked on,

b) the tamper mode is being activated while the unit is in “guard mode”,
the tamper mode will also be able to switch the unit into alarm mode.
