System Operation
**Note** ALL panels in system are pre-programmed at the factory
Alarm
When an input on the PVC-II FACP Interface card is pulled down to circuit common
(0VDC), the Evacuation Signal and Message will be broadcast into the selected Evacuation
Zone. If 'Floor-Above/Floor-Below' has been enabled, the Evacuation Zone for the floor above
and the floor below the selected zone(s) will also be activated.
The floor(s) receiving the Alarm Tone/Message is displayed by a slow (2 second) flashing of the
LED associated with the Evacuation Zone on the Paging Control panel.
If 'Set Alert Non Fire Floors' has been enabled in programming, all floors not broadcasting the
Evacuation Signal and Message will begin broadcasting the Alert Signal and Message.
In addition, if the paging microphone is used and no Evacuation/Paging Zones have been
manually selected, paging will automatically be routed to those zones that are in alarm. The
Evacuation Signal will resume when paging is ended as will the Evacuation Message.
If an Evacuation/Paging Zone is selected manually, paging will take place in the selected zone,
or zones, only (operation if system was designed as “dual” channel)..
Within a single Distributed Panel, and due to the nature of Dual Channel systems using one
amplifier per channel, paging into an Evacuation/Paging Zone broadcasting the Alert Signal and
Message will silence the other zones also broadcasting the Alert Signal and Message if there is
also a zone broadcasting the Alarm Signal and Message. In other words, within a single
Distributed panel only two audible signals can be broadcast at one time, either Alarm and Alert
Signals, Alarm Signal and Paging or Alert Signal and Paging.
Paging
When an Evacuation/Paging Zone is selected by the operator using the associated
switches on the Paging Control panel, the LED(s) will indicate which zone(s) have been selected.
The All-Call switch on the PVC Control panel will select all zones for paging when clicked once. A
second click of the All-Call switch will deselect all zones.
The Zone Selection switches indicate which zones have been selected for paging. Broadcast of
live voice messages does not take place until the Push-to-Talk switch on the microphone is
pressed.
Fire Phone
When a Fire Phone Handset is plugged into a Fire Phone Jack, the LED on the Zone
Control panel associated with that Fire Phone zone will start flashing. A ringing signal will be
heard to indicate that a handset has been jacked in. The ringing signal will cease when the Fire
Phone Zone is selected.
Normally, only one Fire Phone Zone is selected at a time. Selecting another zone where a
handset is jacked in will deselect the other zone(s).
