3.6 DOOR HOLDER OUTPUT
The NZ100 system provides a door holder output, marked D.H on P.C.B. This can provide
12V(nominal) @250mA. This output is switched off during an alarm. It is also switched off ten
minutes after mains failure is detected to conserve battery power.
3.7 WALK TEST
This function is initiated by pressing the walk test button on the API665.When this button is
pressed a LED directly above the switch indicates. While the panel is in the walk test mode the
detectors can be operated in the field and the panel will automatically reset them after a period of
four seconds. To restore the panel to normal operation simply repress the switch and the walk
test indicator will turn off. This Function will operate for ten minute after which it will be
automatically cancelled
3.8 BUZZER
The NZ100 has an internal buzzer, which will sound for any defect, which may occur.
3.9 BUZZER MUTE
Pressing this switch will cause the buzzer to stop sounding for all defects, which are currently
present. Any new defects will cause the buzzer to sound again. The buzzer will also emit a short
beep for confirmation of switch operation.
3.10 DEFECT INDICATORS
Defect indicators are provided on the NZ100 for the following.
(a)
Battery Fault. This indicates one of the following:
Battery voltage is below 12.2 Volts during discharge (mains failure).
Battery voltage is below 12.6 Volts whilst charging.
Battery voltage is above 14 Volts.
Battery is not connected.
Battery failed automatic test.
(b)
Bell Fault. This indicates an open or short circuit on bell line/s.
(c)
System Fault. This indicates mains has failed.
(d)
Zone fault. This indicates a fault on the zone wiring. Normally this would be a short
circuit, however if “SMOKE ONLY” is selected it can also be an open circuit.
3.11 POWER SUPPLY
The API665 has an on board power supply providing 13.5VDC at 0.5A for system power and
charging the system batteries. The system incorporates a test function, controlled by the CPU on
the API 665, which decreases the power supply output voltage to 10V for forty minutes every two
days to check the condition of the system batteries. If the battery voltage falls below 12.2V during
the test period a defect signal is generated and the battery fault LED is illuminated.
