ED816A Addressable Fire and gas detection Installation manual 8-9-08 Rev-a

The ED722 and ED726 loop driver can provide 300mA of continuous loop current, driving up to

126 devices using Apollo S90, XP95 or Discovery protocol.

Each loop is fully isolated electrically from the input power supply, giving continued operation

in the event of earth faults on the dc input, greatly increasing immunity to electrical noise and

eliminating false alarms due to crosstalk.

The ED722 and ED726 are similar but the ED726 can also accept up to 10 EDL addressable

gas detection interface modules. Both models are available with front panels, as used in the

ED700A 8 Loop Control Panel, or without front panels for use in the ED816A. For the full

failsafe features to be available on the ED816A the ED722 / ED726 front panel lamps and

switches are relocated on the ED816A I/O motherboard.

FAIL SAFE OPERATION

Each module within the system (ED722/6 loop modules, ED816A Display module and ED816

I/O module) communicate with each other using an industry standard I2C bus. In the event of

a communications failure, or a fault developing on any of the modules, creating a

communications failure, the loop cards continue to operate autonomously.

The loop modules are directly connected to the following normally energised relays mounted

on the IO module.

HWFD = normally open contact closing to 470 ohms in the alarm condition.

PRE = Pre-alarm.

IMM = Immediate Fire or Gas Alarm.

DEL = Operates 2 minutes after an alarm if mute or reset has not been pressed.

FLT = Fault.

Sounder 1 is directly connected to the alarm relay.

DISCOVERY CONVENTIONAL MODE (Hardware Fire Detection HWFD)

Not to be confused with conventional fire zones, conventional mode, built into the Discovery

detectors and Electronic Devices gas detector interface, provides continued alarm detection in

the event of limited circuit failure. E.g. Microprocessor failure on the loop module resulting in

panel to detector communications failure. Conventional mode becomes operational

approximately 2 minutes after loop to detector communications has failed. Electronic Devices

recommend using Discovery detectors to take advantage of this feature.

PUSH BUTTON OPERATION

If pressed under normal operating conditions the three push buttons operate as lamp test

buttons only. However in the event of a communications error or fault on the Addressable

display module, the loop cards continue to operate autonomously and the push buttons will

function as labelled. See page 29 for details.

These should be used for all safety critical operations as they are operated

in the fail safe mode.

ED816A Input / Output Module

-6-

The Input / Output module provides all of the facilities required for most applications, eliminating the need to

purchase additional add-on modules or interface units.

Designed with ease of installation in mind the I/O Module is fitted with large terminals capable of easily

accepting 4mm square conductors.

The I/O module provides the following:

Loop input / output terminals for up to 2 loops.

2 x Conventional Fire Detection Zones, ideal for utilising existing conventional detectors when retro fitting.

Suitable detectors are Apollo S60 / S65, Apollo Orbis, Tyco M600 and the Hochiki CDX range.

1 x RS232 Comms port for connection to a PC or a laptop running Electronic Devices FireConfig.exe Windows

software Application. Use a straight through (not null modem) serial cable with a 9 pin D type male

connector on one end and female on the other. If using a laptop which does not have a suitable serial port

you will also need a USB to Serial port converter.

1 x RS485 Full Duplex Comms port for connection to up to 8 Repeater modules.

1 x HWFD Relay Output, (Hardware Fire Detection). Normally energised relay output for connection to

additional control panels or third party conventional / addressable fire panel. The HWFD contacts are

normally open and close to 470 Ohms in the event of an alarm condition. Importantly this relay will

continue to operate correctly in the event of internal panel communications failure and also loop

communications failure (discovery detectors and EDL gas detectors only).

All relays are Voltage free change over contacts. All are rated at 2.5A @ 30V d.c. non inductive.

1 x Fire Alarm Relay, fail safe hardware driven.

1 x Delayed Fire Alarm Relay.

Section 2 - System design guidelines

LOOP LENGTHS

LOOP LOADING - Maximum number of addresses

LOOP LOADING - Short circuit isolators

LOOP CABLE SELECTION

LOOP CABLE RESISTANCE

The maximum permitted loop length can be determined using Apollo’s loop calculator, available free from EDL.

Remember to include the vertical distances when looking at plan drawings and also ensure cable capacitance is

within the panels specification.

The maximum number of addresses is 126 per loop. System designers should avoid fully loading loops. The

optimum number of addresses per loop is approximately 90 to 100, this ensures the system is operating well

within its capacity and allows the customer flexibility in the future to add additional devices.

Short circuit isolators should be fitted with no more than 20 detectors between isolators. No more than 10

detectors (or equivalent load) between the panel and the first isolator and no more than 10 detectors (or

equivalent load) between the panel and last isolator. Ideally the first and last items fitted to a loop should be

isolators.

Isolators should always be fitted at zone boundaries and it is good practice to reduce the number of times loop

wiring enters and leaves the same zone. A single fault on a loop should not remove protection from an area

greater than a single zone.

Two simultaneous faults on a loop should not remove protection from an area greater than 10,000 sq m . This

requirement limits the total floor area covered by one loop to 10,000 sq m regardless of the number of

detectors.

Isolators are available as standalone or built in to detector bases and integrated in to Apollo interface modules .

The additional cost of the built in isolators is small compared to the non isolated bases or interface units

therefore as many isolators should be fitted as possible.

Short circuit isolators do not use up addresses and there is no limit to the number of isolators fitted.

Each loop card is fitted with two onboard short circuit isolators, one for loop out and one for loop return,

protecting the wiring between the panel and first and last isolator.

The cable must be a suitable type e.g. FireTuf, FP200 or equivalent and must have the following characteristics:

1. The cable must be 2 core with screen + drain core.

2. Loop out and loop in should never be run within the same cable.

3. Multicore cable should never be used.

The maximum permissible resistance per core is 12.8 Ohms at maximum load (300mA). Loops with lower

loads can accept higher cable resistance, however it is good practice to consider the maximum load at the

design stage thus allowing for future expansion.

Core diameter Typical resistance (FP200 / FireTuf)

1.0mm 18.1 Ohms/Km/Core

1.5mm 12.1 Ohms/Km/Core

2.5mm 7.4 Ohms/Km/Core

4.0mm 4.6 Ohms/Km/Core

ED816A Addressable Fire and gas detection Installation manual 8-9-08 Rev-a

System design guidelines - continued

LOOP CABLE CAPACITANCE

SCREEN CONTINUITY

REPEATER CABLE SELECTION

POWER SUPPLY

Cable capacitance is an important consideration when choosing loop cable.

The maximum permissible capacitance is 0.5uF (500nF) between loop + and loop -.

As each loop is electrically isolated therefore high loop to screen capacitance does not normally cause a

problem and should not be the limiting factor for loop lengths.

Typical capacitance per 100m (FP200 / FireTuf)

Core diameter core to core core to screen

1.0mm 10nF 17.5nF

1.5mm 12nF 20.5nF

2.5mm 13nF 24.0nF

It is vital, for correct and trouble free operation, that the screen is continuous along the full loop length. Ensure

that the screen connection is continued at each loop device. The screen should be earthed at one end only, via

the control panel, and never at loop devices.

All cables entering the control unit should be screened and ferrite sleeves, supplied with the control unit, must

be used. All screens should be terminated at the control panel only thereby avoiding earth loops.

See page 9 for connection diagram.

Note the repeater data cable screens must NOT be connected to the enclosure (earth) and instead connected

to the terminals marked SCRN inside the control unit and repeater units.

The repeater communicates with the control panel using the industry standard RS485 full duplex.

The data cable used should be 2 conductor (twisted) 124 Ohm twinixial 25 AWG (0.16 sq mm) with foil screen

and drain wire. E.g. Beldon 9271 006 (BLULT).

Repeaters can be powered locally to avoid running additional power cables or they can be powered from the

control unit using the fused output terminals. Up to 8 repeaters can be connected to each system, however if

powered from the control panel the repeater current consumption should be included in power supply and

battery calculations.

Each repeater can operate from 18 - 30Vdc with a worst case current consumption of 350mA.

See page 10 for connection diagram.

The control unit requires a nominal 24V dc supply and must always have batteries connected. Normally the AC

mains is connected to the AC mains input terminals and the AC mains output terminals are wired to the external

power supply. The power supplies DC output is connected to the systems main DC input terminals.

Auxiliary DC input terminals are provided as an additional option. The DC input and Auxiliary (if used) must be

suitably rated to charge the internal batteries.

All power supply cables must be screened and ferrite rings used and cables should not be routed near EMC

generating equipment, radio transmitters, paging systems etc., See page 9.

WARNING: Please read this section completely before commencing installation.

The panel must be located in a clean, dry position at least 2 metres away from any radio transmitting equipment

e.g Pager systems.

NOTE

When changing any plug-in cards or loop devices, observe anti-static precautions. Ensure that all power is

removed and the system is switched off. Failure to do so may result in damage to the cards or panel.

The panel be switched off before removing or replacing any card or module. Failure to observe this may

cause damage to the printed circuit boards.

Each loop card has an ID, set via the dip switches mounted on each loop card. No two loop card should have

the same ID.

FireConfig.exe must be used for initial system setup.

The Mains supply should be installed in accordance with the current edition of the IEE wiring regulations.

Connection to the mains supply must be via an isolating protective device (e.g. an isolating fuse) reserved

solely for the fire alarm system. It should be insured that all isolating switches, circuit breakers etc., connected

to the system should be labelled “FIRE ALARM DO NOT SWITCH OFF”.

Correct earthing is vital for trouble free operation. The earth connection should be as short as possible, using

4mm square conductors, connected directly to a good quality earth. The earth should not be routed via radio

transmitting devices or other electrical equipment.

All cables entering the control unit should be screened and ferrite sleeves, supplied with the control unit, should

be used. All screens should be terminated at the cable gland. Only metal, EMC shielding cable glands should

be used. Screens should be continuous and have continuity along the entire length of the cable. Only connect

the screen to earth at one end thus avoiding earth loops. All unscreened conductors should be kept as short as

possible and the ferrite ring should be as close to the cable gland as possible. Wrap each conductor around the

ferrite at least twice. Any communication faults experienced are likely to be caused by poor EMC shielding

practices. Repeater cable screens should never be connected to earth, always use the terminals provided.
