2. The BiWire Flexi Fire Detection & Alarm
System
The BiWire Flexi fire alarm system is a highly adaptable
and intelligent product designed with the simplicity of a
conventional fire alarm system, enhanced to provide multi-
function fire detection and condition indication capability. The
Fire panel supports switchable zones that can be configured
for BiWire Mode that has detectors, call points, sounders,
and Visual Alarm Devices (VAD) combined on the zone, or
Conventional Mode (Standard or Intrinsically Safe Mode) that
only allows detectors and call points on the zone. BiWire
Mode eliminates the requirement to have separate sounder
circuits as with standard conventional systems, but the
BiWire Flexi also comes with conventional sounder circuits
to provide a purely conventional solution or a configurable
retro-fit solution.
The BiWire Flexi fire alarm system is certified to EN54 part
2 and part 4 and is designed to meet the recommendations
in BS5839.
The panels have the following optional features as standard:
• FIRE ALARM DEVICES: (EN54 part 2 clause 7.8)
• TEST CONDITION: (EN54 part 2 clause 10)
• Control of fire alarm routing equipment (EN54 part 2
clause 7.9.1)
• Output to fire protection equipment (EN54 part 2 clause
7.10.1)
The components of the BiWire Flexi Fire System are as
follows:
• The Fire Panel is available to support 2, 4, and 8 Detection
Zones. Each zone can be configured with up to 32 input
devices (including detectors and manual call points) and 20
output devices connected via a single 2-core screened cable.
• The Fire Panel is available to support 4 conventional
sounder circuits (see technical specification for loading
characteristics) that can be used regardless of whether the
zones are configured for BiWire or Conventional modes.
• The integrated EN54 part 4 compliant power supply
charges and monitors two 12V 5Ah batteries. The power
supply is capable of providing up to 24-hour standby
depending on the system loading (further information on
this can be found in the Technical information section of this
document).
• When a zone is configured as BiWire mode, each zone
must be terminated with an intelligent end of line monitoring
module called the EOLM-3™. When a zone is configured for
Conventional mode, each zone must be terminated with an
EOLM-1 (for backward compatibility). Both EOLM modules
need to be located with the last device on the zone.
The BiWire Flexi Fire Detection & Alarm System
• The Fire alarm system has an options interface board
to provide outputs to Fire Protection Equipment (FPE), Fire
Routing Equipment (FRE) and zonal relays. This interface
and the relevant conformance requirements are further
described within this guide.
• The BiWire Flexi panel is only compatible with BiWire
Ultra range of devices for zones configured for BiWire
mode, and is also compatible with the standard Eaton range
of conventional devices on both conventional zones and
sounder circuits. When a conventional zone is configured
for Intrinsically Safe mode then intrinsically safe detectors
can be fitted in conjunction with an isolation barrier (see
technical specifications for more details).
