3.4 DETECTOR CIRCUITS
The detector circuits can accept smoke detectors, heat detectors or manual call points. Detectors
and manual call point types used are subject to the compatibility limitations as described in
section 4.
Open circuit operating devices will cause the panel to go into alarm in one second. Devices such
as smoke detectors, which signal by increasing line current, can, when signalling, go through
“gating” or Alarm Verification. As such, when a detector goes into alarm, it is reset and not
monitored for two to three seconds, if an alarm is still present after this time, the system will then
latch into alarm. This function may be de-selected if not required by removing link K2. See
section 5 for details.
Important: Detector
line voltage is 22V (open circuit). Current signalling detectors (smoke or
electronic heat) must be rated for 24V operation.
3.5 BELL CIRCUITS
The NZ100 provides a monitored bell circuit split to drive up to three (3) Amps of alarm load. The
circuit is split into two parallel lines, which must be less than three (3) Amps total. Each line
requires a 10K EOL resistor to give a system normal indication. If either output line is open or
shorted, a defect signal is generated and the “BELLS” defect LED is illuminated.
See section 4 for connection details.
