3.3.1 Detection Zones
This menu configures each of the three detection zone input circuits. Highlight the DETECTION option and
press the button. The following Zone Select Menu will be shown.
[Zone Select]
ZONE 1 .
ZONE 2
ZONE 3
LEARN ZONE LOADS
(loads learned)
Use the buttons to highlight the required zone and
then press the button to select it.
A menu of parameters is then presented for the selected
zone.
Select the Learn Zone Load option and follow instructions
to maximise zone sensitivity to open-circuit conditions.
Note that the Learn Zone Load process must only be performed when all detection zones are in their normal
operating state. The process should be repeated whenever any changes to the zone configuration are made.
The presence of the “(loads learned)” text indicates that the process has been compled successfully.
The Learn Zone Load process must be completed to ensure that the system complies fully
with the requirements of EN54-13.
[Zone 1 Settings]
SNDR DELAY : 0 .
VERIFY TIME : 0
I.S. ZONE : NO
SHORT=ALARM : NO
NON-LATCH : NO
Use the buttons to highlight the required parameter
and then press the button to select / change it.
The table below details the parameters can be adjusted:
Determines if the sounders are to be delayed before operating
when the panel detects a fire alarm from this zone.
Determines the minimum time that the circuit must be in the
alarm condition before an alarm condition is registered.
Determines whether the circuit is for use with Intrinsic Safety
Barriers.
Determines if a short circuit is to be treated as an alarm
condition. If selected, the short circuit supervision on this circuit
is disabled. Normally, AFD or MCP devices will switch the circuit
into the alarm state via a 270Ω-470Ω resistor / equivalent load.
Determines if the panel should automatically reset from the
alarm condition if the alarm is cleared.
3.3.2 Alarms
SNDR3 is dedicated to the flooding zone (protected area) sounders and is part of the ECD. SNDR1 & SNDR2
are general fire alarm sounders.
