USER’S GUIDE

844 MC-R AUTOMATION

Read the instructions carefully before using the product and
keep them for future reference.

GENERAL SAFETY RULES

The 844 MC-R automation, when installed and used correctly,
affords a high level of safety.
However, some simple rules should be followed to avoid
accidents:

- Do not stand in the vicinity of the automation or allow anyone

else, especially children, to do so, and do not place objects
in the vicinity of the automation. This is particularly important
during operation.

- Keep remote controls or any other control devices out of the

reach of children to prevent them from accidentally operat-
ing the automation.

- Do not allow children to play with the automation.
- Do not deliberately obstruct the movement of the gate.
- Make sure that branches or bushes do not interfere with the

movement of the gate.

- Ensure that the signalling lights are efficient and clearly

visible.

- Do not attempt to move the gate manually without first

releasing it.

- In the event of a malfunction, release the gate to allow

access and call a qualified technician for service.

- If you have to use the release device to set manual opera-

tion, disconnect the electrical power supply.

- Do not make any modifications to components of the auto-

mation system.

- Do not attempt to perform any repair work or tamper with the

automation. Call FAAC qualified personnel for repairs.

- At least once every six months have the automation, the

safety devices and the earth connection checked by a
qualified technician.

DESCRIPTION

The FAAC 844 MC-R automation is ideal for controlling vehicle
access areas with medium-high transit frequencies.
The FAAC model 844 MC-R automation for sliding gates are
electromechanical operators which transmit movement to
the leaf by means of a pinion with rack or chain coupled in
appropriate manner to the sliding gate.
The operation of the sliding gate is controlled by an electronic
control unit housed inside the operator.
When the gate is closed, on receipt of an opening impulse
from  a remote control or other suitable control device, the
control unit will start the motor to move the gate to the open
position.
If automatic operation has been selected, sending an impulse
causes the gate to reclose on its own after the selected pause
time.
If semiautomatic operation has been selected, a second
impulse must be sent to reclose the gate.
An opening impulse sent while the gate is reclosing causes it to
change direction of movement.
A stop command (if available) stops movement at any time.
For detailed information on operation of the sliding gate in the
various operating modes, contact the installation technician.
The automations have safety devices (photocells) which
prevent the gate from reclosing when an obstacle lies within
the area they are protecting.
The system allows the gate to be moved manually when the
motor is not running, so an electric lock must be installed to
keep the gate locked when closed.
In the event of a malfunction or power failure, the gate can be
opened only by releasing the electric lock.
The gear motor has a mechanical clutch which affords the
necessary anti-crushing safety.

The electronic control unit can be incorporated into the gear
motor or installed separately.
A convenient manual release device allows the gate to be
operated in the event of a power failure or malfunction.
The light flashes while the gate is moving.

MANUAL OPERATION

If the gate has to be opened manually due to a power failure
or a malfunction of the automation, the electric lock must be
released. If this is not sufficient (serious mechanical malfunction
of the gear motor), the following operations must be performed
on the release device.
1)

Open the lock cover plate and insert the key supplied in
the lock (Fig.1).

2)

Turn the key clockwise and pull the release lever as shown
in Fig. 2.

3)

Open or close the gate manually.

RETURN TO NORMAL OPERATION

To prevent accidental operation of the gate during this
procedure, turn off the electricity supply to the system before
relocking the operator.
1)

Reclose the release lever.

2)

Turn the key anti-clockwise.

3)

Remove the key and close lock cover plate.

4)

Move the gate until the release device engages.
