SYSTEM DESCRIPTION
3.1
GENERAL DESCRIPTION The NZ100 is an automatic fire alarm system. The NZ100 has one fire detection circuit able to accommodate heat detectors, smoke detectors, manual call points or a combination of these devices. The NZ100 has a bell output to alert personnel in the event of a fire. This output is monitored. All circuitry except for the front panel LEDs is on a single printed circuit board.

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.

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.
3.11
(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.
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.

BATTERIES The NZ100 system is designed to accept one 12V, 7 AH sealed lead acid battery. This should provide more than 240 hours of backup capacity leaving sufficient capacity to drive the alarm load for the required 30 minutes.

CONNECTING DEVICES
4.1
DETECTORS Devices such as heat detectors or manual call points which are normally closed, open circuiting for the alarm condition will give a fire signal within one second of operating. Devices, which increase the current in the detector line such as smoke detectors, may be operated with “gating” (alarm verification) as per section 3.4 to eliminate false alarms due to transient conditions. See also section 5 for details on alarm verification settings. Note: These detectors must not directly short the line as a short circuit gives a defect signal. Devices that have closing contact outputs, such as beam detectors, should have a resistor, in the range of 220ohm to 560ohm installed in series with the contacts. Each circuit must be terminated with an end of line resistor with a value of 6.8K (2% tolerance or better, power rating 1/4W)

THIS DRAWING IS INDICATIVE OF WIRING ONLY. ANY COMBINATION OF DETECTORS AND MANUAL CALL POINTS WITHIN SPECIFIED LIMITS IS PERMISSABLE.
4.2
DETECTOR LIMITATIONS Most detectors, with the exception of thermostatic heat detectors, draw a small monitoring current and this limits the number detectors which can be connected to a given zone circuit. The total quiescent current of all devices on a zone circuit must be less than 1.6mA @ 24V to ensure correct operation. Appendix A lists the number of detector types which may be fitted to a zone circuit.
4.3
BELLS AND SOUNDERS Two bell/sounder circuits are provided, capable of driving a combined load of three (3) Amps. These lines are monitored using a small current in reverse polarity to normal operation. For this reason it is necessary to connect the bells via diodes, 1N4004 diodes are recommended, as shown in Figure 4.2. Also observe bell/sounder polarity.

SETTINGS The NZ100 system has two (2) link options. These are set by simply fitting or removing the jumper plug. If removing a jumper link, it is a good idea to refit it to one of the header pins. This will avoid losing the jumper, which may be required at a later date. Important: There is also a link K3 for use during factory testing, this must not be fitted.
5.1
SMOKE ONLY If link K1 is fitted then the NZ100 will not sense manual call points or thermostatic heat detectors. This allows the removal of a smoke detector head to initiate a defect instead of an alarm. If desired electronic heat detectors may still be used on the “SMOKE ONLY” setting as these operate similarly to smoke detectors.
5.2
GATING “GATING” is an automatic verification facility to reduce nuisance alarms caused by a transient condition. When the “GATING” link (K2) has been fitted, the signal from smoke detectors and electronic heat detectors is verified before an alarm is recognised.

SYSTEM OPERATION
7.1
RESETTING THE SYSTEM To reset the system after a fire, press the ‘RESET’ button on the API665. This will return the system back to its normal state. The buzzer will sound for confirmation.
7.2
USING THE WALK TEST FACILITY. To start the walk test facility, press the ‘Walk Test’ switch on the API665. The buzzer will beep once and the LED above the switch will illuminate. The detectors can now be tested. As a detector is set into alarm the system will operate as normal, except that after approximately four seconds the detectors on the circuit in alarm will be reset. After testing is complete, press the ‘Walk Test’ switch to return to normal. The walk test facility has an internal time out and will be de-selected automatically after ten (10) minutes of operation.
7.3
TRIAL EVACUATION. On the door of the NZ100 a key switch is provided for Trial Evacuation, operating this key switch will cause the system to operate the bells. This will override any other bell isolate or silence condition.
