Ansul AUTOPULSE IQ-396X - PAS Operation and System Timers; System Operational Modes: Waterflow, Disable;Enable, Style 6

AUTOPULSE IQ-396X Operations Doc. 50403:B 07/22/96 11
Zone F0 is reserved for Presignal functions. Zone F0 can be used to delay
control points until an operator verifies an active control point. If including
zone F0 in a CMX or NAC CBE list, zone F0 overrides of all other CBE
actions. Detectors and monitor modules must list zone F0 in the CBE to be
included in the Presignal/PAS operation.

Figure 15: Presignal Operation
At the first alarm, a programmable 0180 second timer starts. If a Signal
Silence occurs, the timer stops. If the delay timer expires, manual activation
will activate outputs mapped to zone F0. The System Alarm relay, the 4XTM
Polarity Reversal Alarm Output, and the 4XTM Municipal Box Output delay if
PAS is selected, but do not delay for Presignal operations.

Alarm Sequence (PAS)
Operation
The control panel can operate with special system timers: Silence Inhibit,
Auto Silence, and Alarm Verification. Figure 16 contains descriptions of how
each timer works.
Special System Timers
Disabled input points do not cause an alarm or any Control-by-Event activity.
The control panel does the following:
 holds all disabled output points in the off-state; and
 handles all disabled points as troubles, but displays DISABL in the status
banner.
If an alarm originates from a monitor point with a waterflow type code, the
control panel disables the Alarm Silence switch. Refer to the IQ-396X
Installation Manual for information on Waterflow Circuits.
The control panel will detect a trouble in an SLC wired and programmed for
Style 6 or Style 7 and drive both ends of the line to maintain communication
over the loop. The trouble latches and displays on the panel as a Style 6
trouble type until you press <System Reset>. Style 7 requires use of ISO-X
modules.
