Passcode No Schedule Supervision (PCNS)
With this type of service, the CCC:
•
Supervision is limited to Closing Troubles and No Close conditions.
•
Monitors alarm and trouble signals generated by the BA group.
•
Does not supervise the schedules of openings and closings.
•
Logs the openings and closings along with ID codes.
•
Logs No Close signals.
With this type of service, the control unit:
•
Is programmed with a permanent close time only, which can be changed temporarily.
•
Does not monitor for irregular opening conditions.
To establish PCNS service, you must, via downline loading only, program the following:
•
The closing time for the Permanent Closing Schedule for the BA group. The control unit
provides No Close supervision based on this closing time.
•
NO for the general control unit option "PVF From Control." This inhibits an irregular opening
signal.
•
NO for the SANS option for the BA group.
•
Any or all ID codes associated with BA groups using this service as being changeable.
4.
Local Closing Supervision (LCS)
This service qualifies for UL Central Station Connect Certification. This service is a form of SANS
service (see next item) and differs from PCNS service in that the control unit:
•
Only sends Alarms, Troubles, No Close, and Closing Troubles.
•
Does not transmit Openings, Closings, Change Closing Time, or Bypass at Close points.
•
Is programmed with a permanent close time only (no opening), which can be changed
temporarily by someone with an ID code having a temporary change privilege.
To establish LCS service, you must, via downline loading only, program the following:
•
The closing time for the Permanent Closing Schedule for the BA group. The control unit
provides No Close supervision based on this closing time.
•
NO for the general control unit option "PVF From Control." This inhibits an irregular opening
signal.
•
YES for the SANS option for the BA group.
•
Any or all ID codes associated with BA groups using this service as being changeable.
5.
Alarm Events Only (SANS)
The control unit will transmit only alarms and troubles to the CCC. No BA group openings or
closings will be transmitted.
To establish SANS service, you must, via downline loading only, program:
•
NO for the general control unit option "PVF From Control." This inhibits an irregular opening
signal.
•
YES for the SANS option for the BA group.
•
Any or all ID codes associated with BA groups using this service as changeable.
Note:
Do not program the Permanent Closing Schedule for the BA group.
