The peripherals with visible terminals and which do not have an anti-tamper device can still be equipped
with protection by intervening on the assembly procedure.
Please note that in order to comply with security standards, all the control panel peripherals must be pro-
tected against tamper.
Here we provide information on one of the possible procedures that can be adopted. This involves the
assembly of a microswitch on the device, which signals any attempted tamper, and the consequent pro-
gramming of the terminal used for this contact.
1.
Procure a microswitch with at least two normally-open contacts
[A]
(preferably with 3 contacts: COM-
NO-NC).
2.
Employ a terminal and program it as a ‘24H’ input, whose description type is ‘Tamper’, balanced with
a single 6K8Ω
[B]
resistance, unlimited alarm cycles and belonging to a partition that is viewable on
at least one keypad.
3.
Using 2 wires, connect the microswitch to the ‘24H’ input terminal.
4.
On the microswitch:
l
identify the common contact (COM) and connect it using one of the two wires, to the GND ter-
minal of the ‘24H’ terminal
[C]
.
l
identify the normally open contact (N.O., which is the contact that generates a short-circuit bet-
ween the contact itself and the COM contact when the switch lever is compressed) and con-
nect one end of the 6k8Ω resistor to it
[D]
.
Connect the other end of the resistance to the wire which is connected to the ‘24H’ input ter-
minal.
5.
Install the microswitch in such a way that under normal conditions the switch lever is compressed.
If a tamper attempt occurs, the lever will release thus generating the opening of the contact and an
immediate alarm on the ‘24H’ terminal.
