and dampers: status switches, differential pressure switches, airflow
paddle switches, current-sensing relays, limit switches, and end switches.
Status switches at fans and dampers monitor the operation of the devices.
Multiple binary inputs at the Tracer MP581s verify the On and Off status
of fans and the Open and Closed status of dampers. If a status switch
does not confirm the commanded (automatic or manual) operation, a Fail
indicator activates at the FSCS. Failure detection must incorporate a
time delay to give the devices time to function.
Differential pressure switches, airflow paddle switches, and current-
sensing relays monitor fan operations. Differential switches piped across
fan and paddle switches in the air stream can give erroneous indications.
IMPORTANT
A current-sensing relay is the preferred way to confirm the operating
status of a fan.
Limit switches and end switches monitor dampers. The switches activate
damper Open and Closed signals for the FSCS. The damper blades
activate the switches. Some codes require two switches in order to sense
both the fully opened and fully closed position of the damper.
Tracer MP581 programmable controller
The Tracer MP581 must have multiple binary inputs to verify the On and
Off operation of fans. It must also have multiple binary inputs to verify
the Open and Closed positions of dampers.
Equipment supervision
Equipment supervision is a pre-installation consideration. Smoke control
equipment must be supervised to ensure it is operational. Supervision
techniques consist of confirming communications among system control
panels, confirming operation in normal use situations, and performing
weekly self-tests.
Confirming communications among all system control panels is a
supervision technique that monitors basic system integrity. If any panel
loses its communications, a Trouble alert is sent to the FSCS.
Normal use operations confirm the integrity of field point wiring for
nondedicated equipment. Nondedicated equipment provides conditioned
air to the building daily. When nondedicated equipment is not
operational, comfort conditions deteriorate and building tenants notify
maintenance personnel.
