Gates
Gates should consist of fence fabric on a rigid frame that includes horizontal and vertical bracing.
•
Firmly attach all gate hardware accessories (minimum free-play).
•
Make sure that double gates have travel stops (rigid anchors).
•
Prevent locking hardware from moving in the wind.
•
Prevent sliding gate track hardware, supports, guides, etc., from rattling in the wind.
There are generally two types of gates used with fences, swinging gates and sliding gates. The
type of gate protection required is determined by:
•
the type of gate
•
the frequency of gate use
•
when the sensor is active
•
the type of ground beneath the gate
•
the overall protection plan (the number of zones and their location relative to the gate in
question)
Gates in a FlexPS zone that are not protected by the sensor are bypassed using non-sensitive
lead-in cable (see
). The lead-in cable is installed inside conduit, underground, from one
side of the gate to the other. The sensor zone continues beyond the gate, and another technology
is used to provide protection in the area of the gate (e.g., a microwave sensor).
Occasionally, it is not possible to dig underground to continue the active zone coverage on the
other side of a gate. There are three standard solutions for this situation:
•
Install the cable on the ground surface, under a secured, protective cable mat.
•
End the zone at the gate.
•
Connect the cable across the gate using quick-disconnect connectors.
Other structures
The FlexPS sensor can be used on other types of fences and structures. It can be deployed on
wooden fences, walls, along the top of concrete or brick walls to detect climb-overs, inside
conduits to protect sensitive data cables, on pipes to prevent sabotage, etc. For installation
information on walls, buildings, wrought iron, or other fence types contact Senstar Customer
Service.
Environment
Ensure that the ambient temperature, as measured inside the enclosure, is within the range of -40
to +70º C (-40 to +158º F). For installations in environments which include hot sunny periods,
install a sun shield to protect the enclosure from direct sunlight, or install the enclosure in a shady
area. Extra care must be taken at sites that experience strong winds on a regular basis. The fence
must be maintained in excellent condition to prevent any metal to metal contact caused by the
wind. All vegetation (weeds, brush, trees, etc.) must be cleared from around the fence area.
Vegetation must not touch or hang over the fence fabric. Any objects that may contact the fence
must also be removed from the perimeter.
Note
Always install and test a short FlexPS zone (< 100 m) before
installing a full system on a non-standard mounting surface.
