System Design

This document does not cover Fire Alarm system design, and a basic understanding is

assumed.

A knowledge of BS5839: Pt 1: 2002: Fire Detection and Alarm Systems for

Buildings is essential.

It is strongly recommended that a suitably qualified and competent person is consulted

in connection with the Fire Alarm System design and that the entire system is

commissioned in accordance with the current national standards and specifications.

Equipment Guarantee

The equipment carries no warranty unless the system is installed, commissioned and

serviced in accordance with this manual and the relevant standards by a suitably

qualified and competent person or organisation

Anti Static Handling Guidelines

Immediately prior to handling any PCBs or other static sensitive devices, it is essential

to ensure that a personal connection to earth is made with an anti-static wrist-

strap or similar apparatus.

Always handle PCBs by their sides and avoid touching any components. PCBs should

also be stored in a clean dry place, which is free from vibration, dust and excessive

heat, and protected from mechanical damage.

ZetaNET Control Panel Installation Instructions

The ZetaNET system is an addressable intelligent detector system, with many advantages over the

traditional addressable analogue detector systems. In order to understand the benefits let us look more

closely at the terms Fire Detector and Fire Sensor. These terms are often used interchangeably but

actually have quite different meanings. A fire detector is the device (component as defined in EN54) which

automatically detects a fire. In the majority of addressable fire detection systems, the fire devices are in fact

fire sensors which only transfer data relating to smoke and heat levels to the control panel, and the fire

decision is made by the panel.

Nearly all current addressable systems are Addressable Analogue Detector Systems where the control

panel continually scans the fire sensors, processes the returned data, and makes decisions about fires and

faults.

The ZetaNET system is defined as an Addressable Intelligent Detector System, or an Addressable Fire

Detection and Alarm System with Independent Distributed Intelligence. Distributed intelligence

signifies that the signal processing is spread throughout the system, in order that the decisions about fires

and faults are taken within the detector itself. The detector is capable of being remotely programmed for

different modes of detection.

Thus the ZetaNET system is indeed an analogue addressable system, but with the processing power

distributed across the entire system. This dramatically reduces the complexity of the control panel and the

data traffic, and improves the efficiency of the system.

The system addressing is carried automatically upon initialisation from the control panel, and does not need

to be programmed manually at each device.

Advantages of Addressable Systems.

The nature of a microprocessor control system with individually identified devices means that the precise

location of fires and faults may be indicated, more complex actions may be implemented, system flexibility

is improved and installation and cabling costs are reduced.

In the ZetaNET system, very efficient communications mean that very low quiescent power consumption

maximises the standby capacity, high power transfer capabilities allow more sounders to be connected to

the loop, and a very fast response to events is achieved as the control panel does not have to poll every

device for status data.

ZetaNET Control Panel Installation Instructions

Control Panel

Mounting the Control Panel

Firstly identify the proposed location for the control panel. Ensure that the control panel will be easily

accessible, and that account is taken of any subsequent work that may affect access. It should be located

at the most likely point of access for the fire services.

The control panel should be mounted on a flat, vertical wall at a height where the indicators may be seen

without difficulty.

Like all electronic equipment, the control panel may be affected by extreme environmental conditions. The

position selected for its installation should therefore be clean and dry, not subjected to high levels of

vibration or shock and at least 2 meters away from any pager or radio transmitting equipment. Ambient

temperatures should be within the range given within the Technical Data section, i.e., not directly over a

radiator or heater.

In common with all microprocessor-controlled panels, the control panel may operate erratically or may be

damaged if subjected to lightening induced transients. Proper earth/ground connections will greatly reduce

susceptibility to this problem.

Cabinet Installation

The four back plate holes should be used to secure the cabinet to a solid wall using suitable screws of at

least 50mm in length.

ZetaNET Control Panel Installation Instructions

Topology & Cabling

All system wiring should be installed to comply with BS 5839: Pt 1: 2002 and BS 7671 (wiring regulations)

and any other standards relevant to the area or type of installation. A cable complying with the BS 5839: Pt

1: 2002 Category 1 (cables required to operate for prolonged periods during fire conditions) is required.

This must be a 2-core 1.5mm

2

screened fire resistant cable.

The addressable circuit must be installed as a loop with a maximum loop length of up to 2 km. Addressable

spur circuits (covering up to a maximum of one detection-zone only per spur circuit and up to a maximum

of 100m in length) may be connected at each Multipoint detector, as long as the combined addressable

circuit length does not exceed 2 km.

The network cable should generally be installed as a single ring, but due to the provision of four network

ports at each panel, sub rings may be installed if required. Whilst radial circuits may be implemented

successfully, they are generally not recommended as they are less fault tolerant and lack system integrity.

Network connections must be installed with a maximum length of 500m between network ports.

The Power Supply Unit requires both a data connection and dual power connections. Thus, one x 2 core

1.5 mm

2

screened fire resistant cable must be installed between the PSU and the Control Panel for data

connections, and 2 x 2.5 mm

2

screened fire resistant cable must be installed between the PSU and the

Control Panel for 24v DC power connections.

In order to protect against possible data corruption it is important ensure the following points are adhered

to:

1. The addressable circuit (loop) cable screen must be connected to earth/ground at the

control panel at each end using the terminals provided.

2. The addressable circuit (loop) cable screen must not be connected to earth/ground at any point

other than the control panel, ie, do not connect the screen to a device back box.

3. The cable screen continuity must be maintained at every point of the loop, using the

terminals provided or a suitable connection block.

4. Do not use a 4-core cable as a loop feed & return due to the possibility of data corruption. It is

essential that two 2-core cables are used if this is required.

5. The network connection cable screens must be connected to earth/ground at the control

panel at one end only using the terminals provided.

Refer to the following wiring schematics for further details.

ZetaNET Control Panel Installation Instructions

Loop Loading

In order to allow a method of calculating the maximum loop loading that the system will support, each

device has a rating assigned in Alarm Loading Units (ALUs). A maximum of 175 ALU are permissible on

the loop. This only relates to the load presented in alarm and does not necessarily affect an input device.

The ZetaNET OSP programming software automatically keeps control of the quantity and will provide

prompts if the limits are reached.

DESCRIPTION ALU RATING

Sounder Low 0.5

Sounder Medium 1

Sounder High 2

Beacon 1

Loop I/O Module 1

Conventional Zone Module: Powered from loop 10

Conventional Zone Module: Powered remotely 1

Note: Whilst the system will operate a maximum of 800 devices per control panel, for compliance with

EN54: Part 2: 1997 it is recommended that a limit of a maximum of 512 detection devices is adhered to.

This includes detectors and manual call points, but does not affect the number of sounders or other alarm

devices on the system.

Outputs 5 and 6: MO+, MO-, SCRN

Outputs 5 and 6 are monitored circuits which may be configured to monitor for open and short circuit faults

with a 10K EOL resistor, and to be activated with a stage 3 alarm.

The default setting for outputs 5 and 6 causes the circuits to operate as Common Fire Sounder Circuits,

where the outputs step up to 28V DC in the alarm condition. Various other states may also be set using the

ZetaNET OSP programming software.

These outputs are protected by the 315mA T fuses labelled F1 and F2.

The Loop 1-4 addressable circuits may be connected to the appropriate End 1 and End 2 terminals.

Communications normally run from Circuit End 1, but in the event of a continuity fault both ends of the

circuit will operate.

It is important that the cable screen is connected to earth at each end at the control panel only, and that the

screen continuity is maintained at all times. We recommend against the use of a 4-core cable as a loop

Feed & Return due to the possibility of data corruption.

Addressable spur (radial) circuits may be connected from any multipoint detector, but not from any other

device. Devices covering a maximum of 1 zone per spur connection may be connected to each circuit in

order to ensure that no more than 1 zone may be lost in the event of a cable failure. Full functionality is

maintained for all spur devices.
