Output: tamper loop [Tmpout]:

Block scheme BANDIT sabotage loop (tamper)

Internal

tamper

side hatch HY-3 pack

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,

(7 BS-software - ; Settings - ; Tamper mode), and;

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.
