4.
If there are multiple problems or ongoing issues, the process in the
previous step can be performed for an entire site. Generally, multiple
problems are a sign of problems in the wiring, either from bad
splices, pinched or nicked wires, radio frequency interference, water
in the conduit, or incorrect wire type. To check an entire site, allow for
access and egress of customers and open the housings and unplug
the power and data terminal blocks on every AI device on the site.
When every device on the site is unplugged, add one device back
into the system at a time. Allow that device to function for an hour
and then add in the next device in line. Eventually, a device will be
added that causes the problem to manifest. Switch this device with
one that has been previously added to verify if the problem exists in
the location or in the device.
5.
Verify that all devices are receiving enough
map of the site by sketching out the locations of every AI device on
the site. Use a multimeter to take DC power readings at each device.
Note these readings on the sketch. Any device that is receiving less
than 12V is underpowered and can cause the entire system to lock up.
Test individual devices
To test individual devices, use the following procedure:
1.
Try a code or card at the
AI device controlling the gate. Be sure
the code or card is one that is known to be working at that location
and time. Try several codes to verify operation. Note which code(s)
were tried and the response at each device as well as the response
that appears on the event log.
2.
Try the same code(s) or card(s) at other access devices on the
property. Compare the result with the previous step. Try to narrow
down which devices are affected.
3.
To determine whether the problem is in the device or the location,
make sure to allow for access and egress of customers and then
remove the device in question. Switch the device with another
similar device that has been proven to be working. For example, if
the entrance keypad isn't working, but the exit one is, then switch
the two. Be sure to switch the addresses also. If the problem stays
in the same location, it is probably a wiring issue. Contact a service
company to check the wiring.

INSTALLATION
Mounting Options
The APEX Access Device controls entry to or exit from a secured area. It
works in conjunction with a controller and control software. The APEX can
be used to control gate access, building access, room access, elevator
access, etc. It is designed for ease of use and fl exibility. Both the keypad
and the large LCD are backlit for easy visibility day and night. Mounting
height for devices will vary with local code regarding handicap access,
emergency and fi re access, and other regulations.
Before installing the APEX, determine where and how the device will be
installed as the mounting location will be determined by how the device is
to be used. If it is to be used for drive up access, it must be installed where
it can be accessed from a vehicle's driver door. If it is to be used for walk up
access, it must be installed where it is easily accessible to a person on foot.
Drive Up Accessibility
When the APEX will be positioned for drive up accessibility, the device
must be mounted within easy reach of the driver of an automobile or light
truck. Most such applications use gooseneck stands that are located on
an island between the entry and exit gates, or to the left side of the gate if a
single gate is used. Local building codes may set a minimum and maximum
height for devices that are accessible by vehicle. Figure 1 shows possible
mounting locations when used for vehicle access.
Walk Up Accessibility
When the APEX is used for walk up access, it can be mounted on a stand
or attached to a wall. It can be surface mounted so that it protrudes from
the wall or it can be fl ush mounted using the optional fl ush mounting kit.
