The following lights indicate the pressure transmitter alarms and failures:
MCR BUS,
PRESSURE,
IN.
MCR BUS indicates the communication bus failure. PRESSURE indicates the pressure sensor
failure. IN indicates discontinuity of the alarm line connected to DI+ and DI-.
The following lights indicate the pressure transmitter status:
POWER,
STATUS.
POWER is always on when the power is supplied to the device. STATUS is always on when

Auxiliary components of mcr EXi-F system

4.3.1.
Intake vent switching system
_____________________________________________
If the air inlets are at the roof level, two air inlets are required, distant from each other and
facing different direction to avoid leeward position in relation to the smoke source. Each inlet should
provide full air supply required by the system. All inlets should be protected by an independent system
of smoke control dampers (when one damper closes due to the smoke, another inlet will supply air
required by the system). The smoke is detected by the smoke detectors upstream of each damper.
An intake vent switching system with two opposed dampers and Belimo B(L)E actuators is
used.
