1.3.2 Detector Circuits TB5 & TB6

The 302-7080 provides connecon to eight zone circuits. All of the detector circuits can be congured

to accept smoke detectors, heat detectors, manual call points or a combinaon of these devices.

Detectors or manual call point types used are subject to the compability limitaons.

Devices such as smoke detectors, which signal by increasing line current, can, when signaling, go

through an oponal Alarm Vericaon Facility (AVF). As such, when a detector goes into alarm, it is

reset and not monitored for six to seven seconds, if an alarm is sll present aer this me, the system

will latch into alarm. This funcon may be de-selected if desired in groups of two.

1.3.3 Bell Circuits TB4

The NZ3200 provides a monitored bell circuit split to drive two x 2Amp circuits. These circuits each

require a 10K EOL resistor to give a system normal indicaon. If circuit is open or shorted, a defect

signal is generated and the “Bells Fault” LED is illuminated.

See secon 4 for connecon details.

1.3.4 Bell Isolate (Internal)

This facility is set or reset by alternate pushes of the bell isolate switch. The yellow LED above the

internal bell isolate switch indicates when the bell is isolated. When the bell is isolated, the bell relay

will not respond to re condions thus enabling the system to be tested without disturbing the building

occupants. This switch is monitored, see secon 4.3.6.

1.3.5 Self Test

Pressing the “Test” buon twice acvates this funcon. This causes the unit to test each zone

sequenally by placing it into alarm and defect condions. When it has completed this test, it will

automacally return to its normal mode of operaon. This self-test may be terminated at any me by

another press of the switch.

During the self test the Fire, Defect and Bell outputs are inhibited.

1.3.6 Walk Test

This funcon is iniated by pressing the “Test” buon once on the Main System Board. When this

buon 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 eld and the panel will automacally reset them aer a period of

four seconds. During the test the bell output and brigade output will operate as normal. To prevent an

unnecessary re call it is recommended to isolate the brigade. To restore the panel to normal operaon

simply repress the switch and the walk test indicator will turn o. This switch is monitored, see secon

4.3.6.

MAN 2338-3

1.3.7 Door Interlock

If any of the monitored switches as listed below within the NZ3200 are not in their normal state when

the door is closed the buzzer will sound to alert the operator to this condion. If the condion is not

reced within two (2) minutes then a defect is signaled.

The following switches are monitored: Isolate, Test, AUX Relay Isolate, Walk Test and Internal Bell

Isolate. If the Walk Test or Internal Bell Isolate are acve when the door is closed, they automacally

return to their normal state aer forty seconds.

Provision is also made for auxiliary switches to be wired into the door interlock warning system via the

interlock input on the Main System Board.

1.3.8 Fault Indicators

Fault indicators are provided on the Main System Board for the following.

(a) Baery Fault. This indicates if the baery voltage is below 24.3 volts.

(b) Bell Fault. This indicates an open or short circuit on bell line/s.

Communicaons fault.

A module is disconnected.

The door was closed with a switch not in its normal posion. See secon 4.3.6.

(d) External defect

(e) Zone defects (eight of)

1.3.9 DBA Input TB2

An input is provided for connecon to any external device providing a Direct Brigade Alarm (DBA)

output, eg sprinkler systems. A short circuit on this line will cause the DBA LED to light and the system

bells to be energised. This input is monitored for normal condion with a 10K resistor. An open circuit

will cause the DEFECT and SYSTEM LED to illuminate and the defect output to be energised.

1.3.10 Power Supply

The Main System Board has an on board switch mode power supply providing 27VDC at 1A for system

power and charging the system baeries. The system incorporates a test funcon, controlled by the

CPU on the 302-708, which decreases the power supply output voltage for forty-ve minutes, every

forty eight hours to check the condion of the system baeries. If the baery voltage falls below 24.3V

during the test period a defect signal is generated and the baery fault LED is illuminated.

The system checks that the baery is connected four mes a minute using the same test as above

except the reduced voltage lasts for half a second.

1.3.11 Mains On Indicator

This LED is illuminated when the main power supply is connected and operaonal.

MAN 2338-3

1.3.12 Ancillary Power Output TB1

A fused power supply output is provided to power ancillary devices. The output is marked +27V and

0V on TB1.

1.3.13 Fusing

The Main System Board has ve fuses:

F1 AC Power supply fuse 3 Amp M205

F2 Power supply output fuse 1 Amp M205

F3 Baery fuse 3 Amp M205

F4 Bell circuit fuse 2 Amp M205

F5 Bell circuit fuse 2 Amp M205

MAN 2338-3

2.2 Bells and Sounders

Two bell/sounder circuits are provided, each capable of driving a 2 Amp load. These lines are monitored

using a small current in reverse polarity to normal. For this reason it is necessary to connect bells via

diodes, 1N4004 diodes are recommended, as shown below. Also observe bell/sounder polarity.

If required these lines can be split to provide three or four bell parallel circuits total, however if this is

done the end of line resistor must be changed. See table below for further detail.

3.3 Operation:

The Amplier is connected to the FACP Bell circuit output as shown in the connecon diagrams. Bell

terminals ‘+’ and ‘-’ are connected to the corresponding ‘+’ and ‘-’ terminals on the amplier.

In the ‘Normal’ state, the FACP monitors the 100V line 10K 1W EOL resistor by applying an inverted

voltage to the amplier input terminals. In this state the amplier connects the 10K 1W EOL line resistor

to the Bell input. A 10K 1W EOL resistor must be used across the 100Vrms line for correct operaon of

the amplier monitoring circuit.

In the ‘Alarm’ state, the FACP reverses the bell voltage causing the amplier to acvate and output a

repeang ‘Evacuaon Tone followed by a voiced Evacuaon Message’ onto the 100Vrms loudspeaker

circuit. The amplier is NOT monitored during the ‘Alarm’ state.

If the amplier output is overloaded, or the supply voltage becomes ‘O-Normal’, the amplier will

signal a defect by turning on the Defect/Fault LED (refer Table 1).

Table 1

The 100Vrms Line may have a maximum of three spurs. For these conguraons an EOL resistor of the

appropriate value must be installed at the end of each spur. (See Table 2).

Number Of Spurs

1 x 10K 1W

1 x 22K 1W on each spur

1 x 33K 1W on each spur

Table 2

3.4 Installation Criteria

✓ Capacively-coupled 100Vrms PA Speakers must be used with the 20W Amplier. The capacitor

must be bipolar and able to withstand 250V peak line voltage. The value should be around 1uF

per wa of power for each speaker.

✓ 100Vrms speaker wiring must be separated from ELV (Extra Low Voltage) wiring.

✓ Loading of the 100Vrms line must not exceed 20W.

✓ An excessive load will cause the Amplier to current limit and shutdown. The symptoms for this

may be interrupons in the audio output and two or more ampliers broadcasng out of

synchronizaon.

✓ Loading of the bell output must not exceed the maximum fuse (FACP Bell Circuit Fuse 4 = 2A) or

relay (20W Amplier Line Relay maximum contact current = 3A) rang.
