EN 54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual
7.5 Fire Zone Input Type
Fire input zones can be configured as follows:
a. Latching/non-latching alarms
b. Alarm or for short-circuit operation
c. Auto or manual operation mode
d. Coincident-alarm or separate-alarm detection
e. Setting a Sprinkler Verification Time.
f. EOL Device Type.
7.5.1 Latching/Non-latching Alarms
A detection zone can be configured as latching or non-
latching. When selected as latching, if the panel enters
the fire (or fault) state this condition will remain active
until the panel is reset. When selected as non-latching,
the panel state returns to normal once the input condition
has been cleared. The default is latching.
7.5.2 Alarm or Short-circuit Operation
The panel can be configured to respond to a short-circuit
input on a zone as a fire or fault condition. The default is
fault indication.
Caution: You will contravene the requirements of EN 54-2
if you configure short-circuit as a fire
condition. For guidance, refer to appropriate
local fire standards.
7.5.3 Auto/ Manual Zones
The panel has the following factory-configured default:
a. Odd-numbered zones - manual zone, i.e. no delay to
activation of outputs, used with MCPs. Manual zones
will always cause immediate entry into the Fire state.
b. Even-numbered zones - auto. detection, i.e. if
configured for day-time delay strategy, outputs will
be delayed as per the delay strategy.
Note: If no delay strategy is being used (default panel
setting) this operation has no effect.
Any zone can be configured as manual or auto action.
7.5.4 Coincidence Detection
The panel will, by default, indicate a fire condition when
a single device on a single zone goes into alarm.
The panel can be configured so that to enter a full fire
condition, two zones must be in the fire state. Coincidence
detection is only supported for pairs of zones, i.e. zone 1
concident with 2, zone 3 coincident with 4, etc. When
configured, upon the first zone going into fire the respective
zonal fire indicator illuminates, the panel enters the alert
state but the general fire LED does not light.
Note: Zone pairs set for coincidence detection are forced
to function as auto zones.
On the second fire alarm zone the standard fire sequence
will be followed for both input zones.
EN 54-2 : 8.2.4a) &
ISO 7240-2 : 9.2.4a)
The panel must indicate
a fault condition for a
short circuit.

1. Configuring a local
detection zone as non-
latching contravenes the
requirements of EN54 and
ISO 7240.
2. Reset from an alarm state must be a
manual operation at access Level 2.
