Separate Zones for Trouble/Supervisory?

Besides all the various building zones needed for alarm, are separate zones typically provided for the trouble and supervisory signals?

Thank You

There are separate zones (circuits) dedicated to supervisory functions. Those would be sprinkler valve tamper switches, fire pump conditions, etc.

Every circuit (IDC, NAC, SLC) regardless of what devices are connected is required to be electrically supervised. They must report trouble if something goes wrong with the wiring, a smoke detector is removed, end of line resistor fails, or any other fault condition that would prevent a device from operating correctly.

Ok so one zone total for supervisory “sprinkler valve tamper switches, fire pump conditions” or a separate zone for each supervisory function ("sprinkler valve tamper switches) and other zone for (fire pump etc.).

Thanks

Sprinkler tamper switches close together, like the ones on a fire pump, can be grouped on one circuit. There is a limit on the number of switches that can be grouped. It is better if every switch is a separate circuit which is easier to do with an addressable system.

Every system I ever installed were required to have separate circuits for fire pump conditions. Power fail, phase reversal, and pump running are required to be separately annunciated. On diesel engine fire pumps there are additional circuits to annunciate battery failure and control switch off normal condition.

I’ve seen on some old conventional systems tamper switches that are wired with normally closed contacts to cause a trouble condition on the waterflow zone when the valve is shut. This is not accepted practice nowadays because it does not provide a distinct signal for a trouble vs. supervisory condition, either at the panel display or monitoring station. It should certainly never be done on a panel that has the option of a supervisory zone type.
