Maintenance and Service
This security system requires very little maintenance;
however, you should test the system weekly to ensure it
is working properly. A test schedule and maintenance
program can be arranged. If you notice a change in
operation during normal use or testing, call for service
as soon as possible. Do not attempt to repair the
control panel, keypads, or detectors yourself.
Refer to Figure 1 on page 2 for security company,
contact, and installation information.
Power Failure
If the keypad indicates a power failure and you have
power in the rest of your premises, there may be a
problem with the electrical transformer or circuit
breaker supplying power to your security control panel.
First, check to be sure that the transformer is securely
plugged into the electrical outlet. If it appears to be
damaged in any way, do not attempt to repair it. Call
your security company for service.
Refer to Figure 1 on page 2 for transformer information.
If the transformer is plugged in, check the circuit
breaker supplying power to the outlet. If the breaker is
tripped, check the appliances on the circuit for signs of
electrical problems. Make sure someone has not
intentionally turned the breaker off. When all is clear,
reset the breaker.
Refer to Figure 1 on page 2 for the circuit breaker
number.
How to clean the keypad
If your keypad gets dirty, apply a household glass
cleaner to a clean cloth or paper towel and wipe the
surface. Do not spray any liquid directly onto the
keypad. It could run inside the case and damage
electrical circuits.
