Test multiple devices or 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 the entire site for
problems, use the following procedure:
1. Allow for access and egress of customers and open all device
housings.
2. Unplug the power and data terminal blocks on every AI device on
the site.
3. Once every device on the site is unplugged, add one device at a
time back into the system.
4. Allow the 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. If the problem stays in the same location, it is probably a wiring
issue. Contact a service company to check the wiring.
