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.

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 the information box (refer to Figure 1 on page 2) for

the transformer information and 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.
