Line type
Using the
Ok
key, scroll the various activation types that can be assigned to the detection line:
FIRE ALARM
The line will operate as a fire detection line. Activation of the line will generate a fire alarm. The
line will remain active until the control panel resets.
Modify levels
Position the cursor on this option then press
Ok
to access the detection line
threshold-adjustment wizard (refer to
Chapter 10 - Detection line threshold-
adjustment
for details).
Det.Missing
If this option is enabled, the voltage on the line will be reversed periodically
for several mS, in order to check if any detectors have been removed from
their bases. This function mode can be applied only when bases with diodes
have been suitably wired using an EOL diode/capacitor connected in parallel
(refer to the wiring diagram).
Detect CP
If this option is enabled, the line will discriminate between alarms generated
by call points and detector. Alarms generated by call points will override the
pre-alarm time and activate instant alarms. This option can be enabled only
when the line is wired as indicated in the respective wiring diagram.
Short=Alarm
If this option is enabled, short-circuits on the line will activate the line itself
(depending on the type of line: Alarm, Supervision, etc.).
Night prealarm
If this option is enabled, the line will signal pre-alarm conditions even when
the system is operating in Night Mode (the Pre-alarm feature must also be
enabled).
Verify
If this option is enabled, the control will remove the power from the line (and
its detectors) when it receives an alarm signal from one of the line detectors.
After reset (a few seconds), it will repower the line (and detectors) and will
consider the alarm valid only if the detector signals the condition again within
the preset “Verify alarm time”.
Pre-alarm
If this option is enabled, the control will signal pre-alarm for the pre-set time
when the line tigers an alarm.
Filtered
If this option is enabled, an alarm or fault condition on the line will be
activated only when it persists for a period of time longer than the pre-set
“Filter Time”.
RESET ALARM
The line will operate as a fire detection line. Activation of the line will generate a fire alarm. The
line will remain active until the detectors connected to it remain in alarm status, once the
detectors restore to standby, the signalling on the control panel will stop.
