Indicators, Controls and Operations
Property and
Building Safety
(Monitor)
The operation of the Property and Building Safety input type applies to initiating
circuits associated with property and building safety. Property and building safety
input status may be reflected on property and building safety zone indicators and in
the common queue, with property and building safety having the lowest priority on the
shared display. They may also be programmed to relay, signal, and strobe outputs.
When an un-bypassed property and building safety circuit goes into alarm, the status
display and programmed outputs are activated. When it restores the status display,
the outputs restore unless they are also programmed to other active inputs.
Trouble-Only An alarm condition on an un-bypassed trouble only input initiates the common trouble
sequence as a trouble. The status is reflected on trouble zone indicators and in the
common queue on the shared display with trouble-only as the third priority. They may
also be programmed to relay, signal, and strobe outputs.
Note that the trouble condition initiated as a result of an alarm on a trouble-only input
is separate from the circuit or device supervision trouble.
Remote Switch
Inputs
Remote switch inputs may be used to provide remote control of system common
controls. Remote switches are processed as a toggle operation. When the circuit is
activated it sends an event through the system similar to pressing the switch on the
front panel. When the circuit is restored it is ignored. For example if a remote switch is
associated with the fire drill common control activating it once when drill is not
activated will turn on drill and activating it again will turn off drill.
Remote switches are supervised to ensure that they do not get "stuck" in the "ON"
position. If they remain active for more than 30 seconds a circuit trouble is generated.
Remote switches themselves are not correlated to relay, signal, and strobe outputs
although the feature they are associated with may be.
