Entrapment protection
To comply with the UL325 standard for gate operators every
entrapment zone, as defined in ASTMF2200, must be pro-
tected by two independent entrapment protection devices.
One of the devices is inherent in the FAAC operators or the
control board design, the other can be external, like a pho-
tocell or an edge sensor.
See the following picture for the photocells positioning:
Closing Safety Devices
Opening Safety
Devices
Opening Safety Devices:
Are active only during the gate opening movement, and
are suitable for protecting the area between the opening
leaves and fixed obstacles (walls, etc) agains the risk of
entrapment
Closing Safety Devices:
Are active only during the gate closing movement, and are
suitable for protecting the closing area against the risk of
entrapment.
Monitored Devices:
Additionaly the UL325 standard requires that every external
entrapment protection device must be monitored for
presence and correct operation. The closing safety devices
are always monitored, see the following picture for the wiring
of a pair of photocells as closing safety devices.
NOTE: one closing safety device must always be connected
for the system to work.

ADVANCED PROGRAMMING
OPENING FAIL SAFE:
If this function is activated, it enables the
monitoring of the opening safety photocell
before he opening movement. If the test fails
the gate does not open.

= Disabled
Display
Function
Default
Monitoring of the opening safety devices must be enabled
in the board configuration. To enable it enter in advanced
programming by pressing and holding “F” and then press
“+”, scroll to the “FS” parameter and select “Active”.
6. Connection of Safety devices
16” or less
If an additional monitored opening safety device is
needed it can be connected to the STP input. The “OP”
parameter in the board configuration must be set to active
