4.3 Manual Gate Operation
This operator is equipped with a manual release system that will allow the gate to be pushed open in
the event of a power outage or equipment failure.
There are two manual release systems that are available on this gate operator. The standard type
release is the FAIL-SAFE system (required by many city codes), while an optional release is the
FAIL-SECURE system.
NOTE: Never attempt to manually push open any gate with an operator attached to it until you
have verified that power to the operator has been shut-off.
Emergency Vehicle Access Conditions
The automatic vehicular gate system must be designed to allow access to emergency vehicles under
different operating conditions.
1. During normal powered operation, emergency vehicles access the gate by use of the
emergency vehicle access device installed on your gate system. The type of device that
is used in your community is dependent on your city codes. These devices may include
(but are not limited to) Fire Department lock boxes, Click-2-Enter radio receivers, strobe
light sensors, siren sensors, etc.
2. In the event of a power failure, the emergency vehicle access device may not be
functional because the gate operator is un-powered. If the gate operator is equipped with
a battery back-up system, this system will automatically open the gate when primary (AC)
power is removed. NOTE: DC powered back-up systems are optional and your gate
system may or may not be equipped with one. Check with your installer to determine if
your gate system is equipped with a back-up power system.
3. In the event of a primary (AC) power failure and a back-up system (DC) power failure
(low charged or dead batteries for example), the system must have a release system to
allow the gate to be manually operated. The release device must be accessible from
either side of the gate and must be present so that emergency personnel can gain
access through the gate under this condition.
Fail-Safe Manual Operation
The FAIL-SAFE manual operation system is the most reliable and safest method for placing an
automated gate in manual operation and is the preferred method of emergency gate operation under
worse case conditions by many Fire Chiefs and Building Inspectors and is typically used in CLASS I
and CLASS II applications. This system requires no keys, cranks or other tools for manual gate
operation and is completely automatic. This prevents any delays for emergency vehicle access in the
event that a power outage has occurred.
• When AC power is removed (power failure or switch power off), the operator "FAILS" in a
"SAFE" condition allowing the gate to be manually pushed open without the need of any
tools, keys, cranks or other devices. This assures emergency vehicle access under the
worst-case conditions.
• For manual fail-safe gate operation, turn power to the operator OFF. If a backup power
system is in use, be sure that this power is turned OFF also. Once power is OFF, the gate
can be manually operated.
