3.0 OPERATION:
3.1 MODES OF OPERATION
The PS-24-8MC POWERPATH can provide 24VDC output when initiated by a 8V to 33V (FWR or DC)
appliance (IN1 or IN2) or an open contact (DRY1 or DRY2). The output will remain on until the
deactivation of the input returns it to standby mode.
The outputs can be configured as four Class “B” circuits, two Class “A” circuits, or two Class “B” and one
Class “A” circuits. With the optional plug in PS-4CA module 101648 the unit supports four Class “A”
Notification Appliance Circuits.
Each Class "A" circuit or Class "B" circuit is 3.0 Amps. Total load for the PS-24-8MC NAC circuits shall not
exceed 8.0 Amps.
There are four output modes which can be used with either Class “A” or Class “B” circuits.
NORMAL MODE Used for a constant 24VDC output.
TEMPORAL MODE Provides a temporal output for appliances that can utilize a coded
signal. (i.e. single stroke bells and chimes and some horns) (NOTE:
Do not use with Wheelock AS, NS, RSS appliances.)
IN>OUT SYNC MODE Allows ONLY a coded signal or Wheelock synchronization signal input
to be utilized by the POWERPATH. This signal may come from a
FACP, another PS-24-8MC or a Wheelock Synchronization Module
(SM-12/24 or DSM-12/24). Audibles can also be silenced.
WHEELOCK SYNC MODE Activates the built-in Wheelock Synchronization Mode for use with
patented Wheelock synchronized horns and strobes. Audibles can
also be silenced.
3.2 DIP SWITCH SETTINGS
The following is the DIP Switch settings for the Outputs.
When switches are changed, press SYS RESET and wait 10 seconds before activating.
