Gate automation
changed all that. Nowadays, opening your
entrance gate is as simple as pressing a button on a remote - and brothers and
sisters once again live in harmony.
Modern access control has put at our disposal a world of convenience, an
exciting universe where everything around us can be set in motion at the press
of a button. We are firmly in control of
our surroundings.
However, as with
any automated system, safety is paramount when it comes to automating your
entrance gate. As a
leading South African manufacturer of gate automation and access control
equipment, it is our distinct privilege to be able to share some guidelines for a safe installation.
1. Endstops
Many modern gate operators make use of a current spike to stop the gate in the correct opening
and closing positions. In other words,
when the operator is commencing the limit setup procedure, encountering an
obstruction will induce a current spike which tells the controller that this is
where it must henceforth stop the gate.
If no mechanical endstops are installed, no spike will be read and the
gate will just keep on running and could potentially come off its rail – with
disastrous consequences.
Endstops should
be fitted in both the opening and closing positions, should be constructed from
a robust material such as steel, and must remain fixed even when considerable
force is applied to them. It is
therefore advisable to weld them in place.
2. Guide-rollers
Guide-rollers
are at least as important as endstops, as these devices are what quite
literally keep your gate on the straight and narrow. Without guide-rollers, your gate would wobble
drunkenly from side to side and eventually come crashing down like a felled
animal. It doesn’t take a giant stretch
of the imagination to envisage the damage to property or injury to person that
would result from such an incident.
3. Electrical Safety
Always have a
qualified electrician attend to any high-voltage (higher than 50V) electrical
needs that may arise from installing a gate operator. Depending on where you live, you may also be
required to fit an isolator within arm’s reach of the operator.
Take care not to
short out battery terminals, and ensure that all electrical equipment is
sufficiently earthed, as this will help prevent damage to the devices as well
as electrical shock.
4. Sensitivity Settings
Any gate motor
worth its salt will have adjustable sensitivity settings. While it is at times desirable to have a
lower setting to compensate for environmental changes such as wind loading
(applies more to swing gates) or variations in the track, it is important to
remember that the lower the setting, the harder it will be to stop the gate.
5.
Prevent
Unauthorised Access
Kids (and some
adults) are curious. That is a simple
fact of life. But curiosity can quickly
turn to tragedy if proper care isn’t exercised when it comes to securing gate
motor controls. Ensure that only
authorised adults have access to the controls.
Operator covers should at all times be locked in place and the keys kept
in a safe location.
6. Keep the Area of Travel Clear!
This is arguably
the most important guideline of all. No matter how cautious one purports to be, no matter how vigilant, accidents do happen. Therefore the best course of action is, before attempting to operate an automated gate, to first ensure that no children or pets are in the vicinity. A Courtesy Light can also be installed to provide visual indication prior to and during gate travel.
