1.7 Day/Night Switching Tab
1.7.1 Day Start / Night Start –
These values are the times to the nearest hour at which the day/night switching is desired to take place
on the detector. Entries are made in 24-hour format, for example 19 for 7pm. Day and night switching is
intended so that the detector may automatically select a different sensitivity when the protected area is
unoccupied and fewer contaminants are being produced. ClassiFire automatically detects the change in
smoke level after the protected area is left, and if the time at which this happens is within + 70 minutes of
the programmed switchover time it selects the night-time histogram. This means that changes in time
setting, for example changing to summer time, may be ignored as the detector will take this into account.
The default times for day and night start are 08:00 and 19:00 respectively.
NOTE: That if the environment actually becomes more contaminated during the night period for any
reason then ClassiFire will adapt to that too, reducing the night-time sensitivity.
1.7.2 Disable Day / Night Switching
If day/night switching is not desirable, the Disable day/night switching box may be ticked to leave the
detector permanently in day mode.
1.8 Alarm Actions Tab
1.8.1 Remote Functions (Remote Input subgroup)
These functions have no current use on the FIRElink-100 but are reserved for future expansion purposes.
1.8.2 Programmed Isolate
When this function is ticked the controller will not generate alarms and will not indicate a fault condition on
any fire panel which is connected, for use during detector maintenance for example. The “Fault” light will
be illuminated on the detector front panel. The isolated condition will be disabled automatically after 7
days if not manually disabled. This function is disabled by default.
1.8.3 Latching Alarms
When this function box is ticked it requires a reset from the controlling computer to clear an alarm
condition. If unticked, the alarm signal is extinguished as soon as the alarm condition ends. This is the
factory default setting.
1.8.4 Latching Faults
When this function box is ticked it requires a reset from the controlling computer to clear a fault condition.
If unticked, the fault signal is extinguished as soon as the fault condition ends. This is the factory default
setting.
1.8.5 Cascading Alarms
Ticking this function box means that only when the detector’s controller has gone into Pre-Alarm does the
controller start counting down the main Fire delay, in other words the time delays on Pre-Alarm and Fire 1
are cumulative. The Aux alarm is not included in the cumulative delay since it may be set to a higher
level than either the Pre-Alarm or Fire 1 levels. This function is enabled by default.
