844 ER Z16 CR - 844 R - 844 R CAT - 844 R RF
The FAAC mod. 844 automated system for sliding gates is an
electro-mechanical operator transmitting motion to the sliding leaf
via a rack or chain pinion appropriately coupled to the gate.
The non-reversing system ensures the gate is mechanically locked
when the motor is not operating and, therefore, no lock needs to be
installed.
The gearmotor is equipped with a mechanical clutch which,
combined with an electronic device, offers the necessary adjustable
anti-crushing safety and guarantees stopping or reversing the gate
movement. A handy manual release makes it possible to move the
gate in the event of a power cut or malfunction. The control
board, if supplied with the gearmotor, it is placed inside the
operator.
The 844 automated system was designed and manufactured
to control access of vehicles. Avoid any other use whatever.

MAXIMUM USE CURVE
The curve makes it possible to establish maximum work time (T)
according to use frequency (F).
E.g.: The 844 gearmotor can operate non-stop at 70% use
frequency.
To ensure efficient operation, operate in the work range below the
curve.
Important:
The curve is obtained at a temperature of 24°C. Exposure
to the direct sun rays can reduce use frequency down to 20%.
Calculation of use frequency
The percentage of effective work time (o closing) compared
to total time of cycle (o c pause times).
Calculation formula:
Ta + Tc
%F =
X 100
Ta + Tc + Tp + Ti
