FIREMAN (CP COM OP)
Control input from external 3-way fireman control switch, for manual control of the vent:
•
CL
Activates the vent output (fully close vent)
•
COM Common reference
•
OP
Activates the vent output (fully open vent)
In default condition, operation of this switch will fully open/close the vent, overriding local
switch settings/vent positions.
Note:
If neither input is activated, vent follows panel automatic control.
ACT (+ -)
Dual polarity reversal vent drive actuator outputs - 28VDC, max 8A, protected by a current
trip circuit. Not normally powered. Operated by the inputs from either the main fireman
switch, or the local vent control switch; for a configurable time-period of 10 to 300 seconds.
The default setting is 60 seconds, during configuration of the panel, this should be set to the
time-period required to open/close the vent fully. Polarity is reversed for vent closure.
The resistance of the actuator is monitored. When abov
e 10KΩ it is considered an open
circuit and less than
10Ω it is considered a short circuit. This monitoring is only active when
the actuator is in the fully open or fully closed position. A configuration option allows the
short circuit monitoring to be completely suppressed. This option might not meet the
requirements of local regulations. When used in this mode, connecting resistances of less
than 1Ω can cause damage to the circuitry of the actuator driver.
On commissioning, the vent should be set to the fully closed position prior to connection.
The actuator outputs may be changed to a continuous, maintained operation using DIL
switch 3, ‘ACT POWER’. The control logic can be inverted using DIL switch 1, ‘ACT
INVERT’.
