5.8.1
Common Fault Relay – Detection Module
The common fault relay is normally energised and will de-energise upon any fault condition on the
detection part or the extinguishing part of the control panel, including total loss of power.
The fault relay can be disabled by setting configuration option 22 at Access Level 3, as shown in Table 6
- Detection module configuration options.
Important!
Setting this option does not comply to EN54-2.
5.8.2
Fault Relay – Extinguishing Modules
These fault relays are normally energised and will de-energise upon any fault condition on the
extinguishing module or total loss of power.
5.8.3
Local Fire Relay – Detection Module
The local fire relay will energise upon activation of a fire condition on any of the zones, or by pressing the
sound alarm button on the front panel. The relay will remain activated until the alarm is silenced, or the
panel is reset. This relay will not operate upon activation of the remote AL input, or when a fire condition
is triggered on a zone that is in test mode. This makes the local fire relay suitable for inter panel
signalling without the panels latching each other.
Note.
The local alarm relay can be re-configured using programmable option C2A to operate upon gas
released if required
5.8.4
Fire Relay – Detection Module
The fire relay will energise upon activation of a fire condition on any of the detection zones, or by
pressing the sound alarm button on the front panel. The relay will remain activated until the alarm is
silenced, or the panel is reset. This relay will not operate upon activation of the remote AL input and the
sound alarm button.
The fire relay can be disabled by setting configuration option 26 at Access Level 3 as shown in Table 6 -
Detection module configuration options.
5.8.5
1
st
stage Alarm Relay – Extinguishing Modules
First stage alarm relays will operate upon activation of a zone that has been configured to contribute to
the extinguishing release and will de-activate only when the panel has been reset.
This relay will also operate upon activation of the panel mounted or remote manual release switch.
The stage 1 relay output can be disabled at Access Level 2, via the menus on the extinguishing module.
5.8.6
2nd stage Alarm Relay – Extinguishing Modules
Second stage alarm relays will operate when the panel enters the activated condition (i.e. the release
countdown timer has started) and will de-activate only when the panel has been reset from the released
condition.
The stage 2 relay output can be disabled at Access Level 2, via the menus on the extinguishing module.
