ANTI-TAMPER CONNECTIONS

CON6 is used as an input for an external anti-tamper switch. It is connected in parallel with the built in anti-tamper switch

that is marked in Figure 2.

On the boxed variants, the built in anti-tamper switch is connected in a normally open (N/O) configuration. However, it is

fitted with a spring which is compressed when the module lid is closed, and thus closing the contact. When the lid is

removed, the input is opened and the alarm will be activated.

If the built in anti-tamper switch is not used, CON6 can be connected to an external anti-tamper switch. To do this, the

spring must be removed from the built in anti-tamper switch. CON6 should then be connected to the external anti-tamper

switch in a normally closed (N/C) configuration.
