Waterflow Alarm Input
Waterflow inputs are sampled every second. 10 samples in alarm in any given 15 second
period confirms the alarm condition. Therefore from a continuous input activation the alarm will
be processed within 10s.
LED Indication
The Alarm Zone LED indicator flashes when one sample indicates an alarm condition. If the
alarm is confirmed the LED indicator will illuminate steady. If 15 seconds elapses without any
samples in the alarm condition the LED Indicator will turn OFF. The waterflow retard operation
operates regardless of whether or not the system is in alarm.

Configures (mini) dual input modules as audible when conducting a walktest. For more
information on performing a walktest see 5.10.5 Walk Test.
5.2.9
Silent Test
Configures (mini) dual input modules as silent when conducting a walktest. For more
information on performing a walktest see 5.10.5 Walk Test.

contained within a secured enclosure accessibly only to those with the
proper authority.
