Output Module - Extension Module Type mcr R04xx. Operation and Maintenance Manual.
Strona 5 z 19
If the 230 V~ mains power supply to the module or the control unit is missing, the smoke
vents can only be opened in the event of an alarm; the ventilation function is blocked to protect
the batteries from discharging.
Caution: do not leave the unit without mains power for more than 72 h with the batteries
connected, due to the possibility of damage to the batteries. In case of using the module to
power mcr PROSMOKE FS CE curtains, this time is up to 6.5 h (see operation and
maintenance manual for mcr PROSMOKE FS CE curtains).
4. Transport, delivery, storage
The modules are delivered assembled in individual packages. Batteries are supplied
separately. The devices should be stored in dry rooms, in temperatures 0C÷40C.
5. Module mounting
The module should be mounted near the devices it controls, in a location that allows
access to the device. During mounting, disconnect all power sources to the equipment being
installed.
Use conductor types compliant with the local regulations, with appropriate cross
sections.
Install the module in the following order:
1. Fix the enclosure to the wall with steel fasteners matched to the substrate
material: fasteners with a minimum diameter of Ø8, e.g. M8, are
recommended (note: do not drill holes in walls through the enclosure).
2. Make electrical connections according to the attached diagrams (connect
control units, actuators, line termination resistors).
3. Connect the unit to the mains supply. Attach the connectors to the battery
terminals. Turn on the overcurrent circuit breaker inside the enclosure. The
230 V~ LED should light up. The ACTIVE and FAULT LEDs should remain
unlit; when connected to the mcr 9705 control unit with door automation
function, the ACTIVE LED will be lit.
4. Verify system operation by sounding the alarm from all available sources.
5. The device is ready to operate after the batteries are charged (up to 48 h
after the first mains connection, if the connected actuators are not used).
6. Operation
The module is basically a maintenance-free device; however, to ensure the efficiency
of the smoke ventilation system the condition of the device should be checked according to
the following list:
1. Check the status of the module's control units - whether they signal any damage
(daily).
2. Check the power supply to the extension modules (every 3 days or so). If the power
supply decay has lasted (or is suspected to have lasted) for more than 72 hours,
an authorised "MERCOR" S.A. service centre should be called to check the
batteries' condition. In case of using the module to power mcr PROSMOKE FS CE
curtains, this time is up to 6.5 h (see operation and maintenance manual for mcr
PROSMOKE FS CE curtains)
3. Verify system operation by activating the alarm signal, then clear the alarm signal.
Check that connected devices have opened and closed correctly (1 time per
month).
