1.1.3 The Workstation Supervisor
The workstation supervisor is designed to monitor the workstation. In the event that the software stops running or
the CPU fails, an onboard sounder is activated to notify operators of the problem. The board also has an onboard
output relay to allow annunciation by any external device which uses dry contact inputs. Alarms may be acknowl-
edged by pressing a button on the back of the board.
This board mounts internally in the UWS 586T computer using an ISA slot and a standard mounting bracket.
Power is provided by an external 24VDC source, power limited and regulated with battery backup which is UL/ULC
listed (as appropriate for your area) for use with fire protective signalling units. The unit comes pre-installed and
configured and requires only external power to activate. Maximum power use is 35mA @ 24VDC.
The onboard relay may be wired for normally open (NO) or normally closed (NC) operation by setting jumper JP1
to the desired position. Refer to the board markings for jumper settings. This relay is rated for 1A @ 30VDC.

NOTE: Do not connect power from
a fire alarm panel, as it may cause a
ground fault in the panel.
