27 - EMERGENCY VEHICLE ACCESS
27.1 The automatic vehicular gate system must be designed to allow access
to emergency vehicles under different operating conditions.
27.2 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.
27.3 Check with your installer to determine if your gate system is equipped
with a back-up power system. 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.
27.4 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.
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.
27.6 The automatic vehicular gate system must be designed to allow access
to emergency vehicles under different operating conditions.
27.7 In the event of a power failure, the emergency vehicle access device
may not be functional because the gate operator is un-powered. 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.
27.8 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.
27.9
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, by using
the MANUAL RELEASE handle under the top cover.
28 - GLOSSARY

COMMERCIAL / GENERAL ACCESS VEHICULAR GATE OPERATOR-
CLASS II - A vehicular gate operator (or system) intended for use in a

or more single family units), hotels, garages, retail store, or other building
servicing the general public.
ENTRAPMENT
- The condition when an object is caught or held in a position
that increases the risk of injury.
FORCE STATIC - Constant load threshold for sensitivity setting.
FORCE DYNAMIC - Impact sensitivity setting.
GATE - A moving barrier such as a swinging, sliding, raising, lowering, or the
like, barrier, that is a stand-alone passage barrier or is that portion of a wall
or fence system that controls entrance and/or egress by persons or vehicles
and completes the perimeter of a defined area.
(STEP H) HIGH PRIORITY - Step by step control.
INHERENT ENTRAPMENT SENSOR SYSTEM - An automatic sensor
system which senses entrapment of a solid object and is incorporated as a
permanent and integral part of the operator.
INDUSTRIAL / LIMITED ACCESS VEHICULAR GATE OPERATOR-
CLASS III
- A vehicular gate operator (or system) intended for use in an
industrial location or building such as a factory or loading dock area or other
locations not intended to service the general public.
RESTRICTED ACCESS VEHICULAR GATE OPERATOR-CLASS IV - A
vehicular gate operator (or system) intended for use in a guarded industrial
location or building such as an airport security area or other restricted access
locations not servicing the general public, in which unauthorized access is
prevented via supervision by security personnel.
RESIDENTIAL VEHICULAR GATE OPERATOR-CLASS I - A vehicular
gate operator (or system) intended for use in a home of one-to four single
family dwelling, or garage or parking area associated therewith.
STEP BY STEP - Command that opens-stops-closes-stops the gate with
each press of the button.
SYSTEM - In the context of these requirements, a system refers to a group of
interacting devices intended to perform a common function.
UNBLOCK
- Resumes normal operation after a blocked condition.
WIRED CONTROL - A control implemented in a form of fixed physical
interconnections between the control, the associated devices, and an
operator to perform predetermined functions in response to input signals.
WIRELESS CONTROL - A control implemented in means other than fixed
physical interconnections (such as radio waves or infrared beams) between
the control, the associated devices, and an operator to perform predetermined
functions in response to input signals.
