Conventional Fire Detection and Fire Alarm Control Panel
CLVR02EXT
5 Control panel operation

5.1. Description

Normal operation of this control panel is identical to that described for the zone control panel,
except for the addition of the extinguishing capability.
This means that the CLVR 02Ext model has the functionality of a main fire detection and alarm
control panel in accordance with what is laid down in standards EN 54-2 and EN 54-4, and in
components for extinguishing systems using gaseous agents EN 12094-1.
The normal operation of the added extinguishing capability is described below.
NOTE: VERY IMPORTANT!!!
It can NOT be used Manual Call Points when control panel is installed for an
extinguishing system.
The fire detectors are distributed between 2 zone outputs within the flooding zone, in
accordance with what is laid down in the different standards and regulations which must be
fulfilled, with the requirements of the equipment involved and with the wiring diagrams of this
manual.
When a detector alarms, the control panel goes from the standby condition to the alarm
condition.
The Advance Warning Extinguishing output relay (R1) triggers immediately. In this way, the
warning equipment in the flooding zone is powered up (sounders, signs, etc).
The Advanced Warning Extinguishing output (relay R1) is monitored.
If a second detector in the same zone alarms, the system will remain in the same situation.
When a detector from the other zone activates, it is initiated the delay for triggering of the R2
extinguishing output.
Once the delay is complete, or if it has not been programmed, the extinguishing output (R2) will
trigger.
Exit from this state is only possible by resetting the control panel. To do this, you must wait the
delay time for reset, which can be programmed on the control panel.
If needed, the Extinguishing output (R2) can be triggered or aborted at any time. This can be
carried out by using the control panel or the manual stop and triggering devices located in the
zones surrounding the flooding zone, connected in accordance with the diagrams in this
manual.
Both control key 10 (Activate Extinguishing) of the control panel and the manual triggering
device, shall activate the Extinguishing output immediately (R2). If this key or manual triggering
device is actuated with control panel in standby condition, it will be activated buzzer control
panel and sounder, alarm and advanced warning extinguishing (R1) outputs.
Control key 11 (Stop Extinguishing) of the control panel, and the manual extinguishing stop
device lock the R2 extinguishing output permanently as long as the R2 output has not been
activated. This situation can only be unlocked by resetting the control panel. In the case of
actuating the stop key or the manual extinguishing stop device with control panel in standby
condition, it will be activated buzzer of the control panel.
The operation of R1 output can be modified by the possibilities described in Chapter 7.3.5.
