•
When an un-bypassed building circuit activates, the status display and programmed
outputs are activated.
•
Restoring the building status returns all outputs correlated to the input, that are not
correlated to another active input, to normal.
5.2.4
Priority Alarm
Increases the polling frequency and optimizes the transmission of data from the device.
5.2.5
Trouble-Only Input
An active condition on an un-bypassed trouble-only input initiates the common trouble
sequence as a non-latching trouble.
•
Activates Trouble zone status indicators associated with the input.
•
Trouble input activations display as the lowest priority on the shared display in the
common queue.
•
May also be programmed to relay, signal, and strobe outputs.
5.2.6
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.
5.2.7
System Status Correlations
The following System Status processes can be correlated to configured (mini) dual input
modules:
Note:
Devices used for building inputs are to be isolated from fire operation. It is
required that these devices are placed on a separate SLC loop if Class B (DCLB)
wiring is used, otherwise wire the devices according to Class X (DCLC) to
accomplish isolation.
Note:
Trouble conditions initiated as a result of a trouble-only input activating is
separate from the circuit or device supervision trouble.
Note:
Do not use the retard operation with any external retarding device.
