Tamper Input (J4)
The terminal J4 is used in different ways depending on the country. The
European Versions are supplied with a 3-way block providing a spare
terminal for series connection, and International Versions are supplied
with a 2-way block. J4 can be used for CPU case protection and/or in
series with External Audible Siren connection. (0v and Tamper Return).
This is a 24 hour monitored tamper input and will caused a full alarm
(‘Tamper Alarm’ Type 11) if the circuit is broken during any mode. You
can break the circuit without alarm activation by entering User (Menu
3,4,2) or Engineer (menu 8,2) Walk Test. A tamper switch may be
connected to the TAMPER input (2 pin Terminal J4). If not used, short
the J4 terminal block with a wire. This terminal may be connected to an
external tamper switch of a bell box as well as to the tamper switch of
the control panel enclosure as in Figure 2.12. The tamper switches
may be connected in series as shown below. The Alarm type activated
when the circuit is broken is Tamper (Alarm type 11).
Alternatively, any zone may be programmed as a Tamper zone type.
