Not more than four
24AWG conductors
should be connected to a
single terminal as wire
bulk may cause improper
operation.
All devices must be enrolled as
individual zones on the system
by entering their serial numbers
(see section 3.2 "Enrolling
Devices").
If any of the system keypads indicate a PC5100 module tamper,
or if any zones show as open, or show a zone fault, there may
be a short on the AML loop. The PC5100 module and zones will
not be restored until the short is corrected - remove power
from the system and re-check the zone wiring.
2.4 Connecting the PC5100 Tamper
The PC5100 has a built-in tamper switch (SW1). If an external tamper
switch is being used, connect the switch according to the following
diagram.
If neither the built-in tamper nor an external switch is being
used, you must short the TAM and BLK terminals. If you do not
make this connection, a trouble condition will be indicated.
