NOTE: All detection devices connected to an individual
circuit must be of the same type.
Detection Zones and Zone Expansion
(The CPA6 has six zones. Each zone may have one
circuit only, or can, by the addition of external Zone
Expansion Modules, (Z.E.M.’s) be expanded in
increments of two circuits, up to a maximum of ten (see
figure 1).
Z.E.M’s are housed in small tamper-protected
metal/plastic enclosure and would normally replace a
junction box in the location of the detectors.
The enclosure tamper switch is connected into loop ‘A’
of a Z.E.M. internally.
Two different types of detection circuits may be
connected to a single Z.E.M and each identified during
the commissioning procedure.
Z.E.M’s are interconnected with two wires, the output of
one Z.E.M. connecting to the input of the next. Up to
five
Z.E.M.’s can be connected in this manner into a single
CPA6 zone input.
Circuit identification is achieved by noting the position of
each Z.E.M. in its associated group e.g. Zone 4 circuit 6
refers to the circuit connected to the ‘B’ loop of the third
Z.E.M. on the input to Zone 4 of the panel.
NOTE: Z.E.M. Interconnection is polarity conscious.
When a Zone has only a single circuit wired to it, the
Z.E.M. -ve input connection on the CPA6 PCB is ignored
and the +ve & -ve terminals are used for the detection
circuit, with the E.O.L. terminals providing the end of line
resistor.
Detection circuit wiring to Z.E.M.’s is via terminals ‘Loop A’
and ‘Loop B’ and the E.O.L. resistors must be remote
from the Z.E.M fitted.
Outputs
P.A.
This drives high (to + 12V via a 47R resistor) for
signalling purposes following activation of any
P.A. circuit.
ALARM
This drives high (to + 12V via a 47R resistor) for
signalling purposes following activation of any
detection circuit (
excluding P.A. Circuits
) when
the system is set.
SET
This drives high (to + 12V via a 47R resistor) for
signalling purpose when the alarm system is
set. The output is removed as entry to the
premise commences.
E/E
This drives high (to + 12V via a 47R resistor) when
the system is being set or opened.
24HR/FAULT
This output drives high (to +12V via a 47R resistor)
following operation of 24 hour or tamper circuits
during the day, or any fault condition during
system setting.
BELL RELAY
This output is a voltage-free normally open relay
contact which closes an alarm, following any
programmed bell delay. The contact will
remain closed until either the alarm system is
reset, or a pre-set bell duration time expires.
NOTE: When the panel supply is switched via the relay
contacts to drive an external bell, the bell must be of a
‘suppressed’ type.
AUX SUPPLY
This output is individually fused (FS1) and
provides 13.6 volts dc @
300mA (max) for
external equipment.
SPEAKER
This output drives the integral sounder speaker,
but may also be used to drive an additional
extension speaker (8 Ohm) where required.
