A combination of LEDs and a 4 Line * 20 Character Liquid Crystal Display (LCD) is used to simply convey
information. Messages displayed on the LCD include:-
- Zone Xin fire - Fire activation in zone number 1 to 16
- Fire Panel YZn X- Another fire panel at address 1 to 32 (Y) to which this is networked to, has a Fire
activation in zone 1 to 16 (X).
- Zone XDetectr Fire - An Alarm Sense detector on zone 1 to 16 has a fire activation.
- Zone XCallpnt Fire - An Alarm Sense Call Point on zone 1 to 16 has a fire activation.
- Alarms Silenced - Activated alarms have been switched off.
- Alarms Resounded - Alarms that have been Silenced, have been re-activated.
- Zn XMissng/oper/Eol - Zone 1 to 16 either Detector is missing, or Zone wiring is open circuit or the
End of Line device is missing.
- Zn XShort Circuit - Zone 1 to 16 short circuit.
- Zone XDet Missing - An Alarm Sense detector is removed on zone 1 to 16.
- Panel Evacuated - Evacuate option has been selected.
- Pnl XAL YShort Circuit - Another fire panel at address 1 to 32 (X), to which this is networked to, has an
fault on Alarm Line 1 to 4 (Y).
- Pnl XEoL AL Ymsng - Another fire panel at address 1 to 32, to which this is networked to, is either
Open Circuit or the End of Line EoL device is missing on Alarm Line 1 to 4.
- Fault on Panel X- Another fire panel at address 1 to 32, to which this is networked to, is in a fault
condition. This is qualified by a description of the fault that has occurred.
- RPTR XAL YScct Flt - A repeater panel at address 1 to 32, connected to this panel, has detected a short
circuit on Alarm Line 1 to 4.
- RPTR XAL YOcct Flt - A repeater panel address 1 to 32, connected to this panel, has detected an open
circuit on Alarm Line 1 to 4.
- RPTR XMicro CRC Flt - An error with the controlling software on a repeater panel address 1 to 32 has
been detected.
- Mains Failed - 230VAC input is disconnected.
- Battery Missing - The standby battery is disconnected or faulty.
- Aux 12v Fault - 12v Auxiliary output from the fire panel has failed.
- Aux 24v Fault - 24v Auxiliary output from the fire panel has failed.
- Temp Sensor Fail - Temperature sensor used for battery charging is disconnected or short circuit.
- Earth Fault - A wire/cable connected to the Eurofire panel is shorted to earth.
- Watchdog Reset - Fire panel has been re-started by the supervision circuitry.
Eurofire EN54 is a combined 2 and 4-wire conventional fire detection system that has been designed to comply with
the requirements of EN54 parts 2 and 4.
The standard conventional 4-wire system uses two pairs of wires (4-wire), one pair is used to connect detectors and
call points, the other pair to connect alarm devices (sounders, bells or strobe lights).
The 2-wire convention uses a common pair for the connection of Apollo ‘AlarmSense’ detectors, callpoints and
alarm sounders. This gives the scheme designer a greater flexibility of choice, whilst retaining compliance with the
relevant standards,
Benefits can be seen with time saving, reduced wiring cost, and ease of installation.
The Eurofire EN54 control panel is available as either 4, 8, 12 or 16 zones of fire cover. Other Eurofire EN54 panels
and Repeaters can be networked using the ‘CAN Connect’ link.
