21 - EMERGENCY VEHICLE ACCESS
22 - GLOSSARY
21.1
The automatic vehicular gate system must be designed to allow
access to emergency vehicles under different operating conditions.
21.2
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.
21.3
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.
21.4
If applicable, this system 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.
21.5
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.
21.6
The automatic vehicular gate system must be designed to allow
access to emergency vehicles under different operating conditions.
21.7
In the event of a power failure, the emergency vehicle access device
may not be functional because the gate operator is not 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.
21.8
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 or disconnected. Once power is OFF, the gate can be
manually operated, by disconnecting the gate attachment bracket
(816).
LOCK-
Ceases all operator function except HIGH PRIORITY inputs.
COMMERCIAL / GENERAL ACCESS VEHICULAR GATE OPERATOR-
CLASS II -
A vehicular gate operator (or system) intended for use in a
commercial location or building such as a multi-family housing unit (five
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 a ea.
(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.
UNLOCK -
Resumes normal operation after a blocked condition.
WIRED CONTROL -
A control implemented in a form of fixed physical inter-
connections 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.
