Walk Test LED

CPU Fail LED

Auxiliary Disconnect LED

Signal Silence LED

Battery Trouble LED

Ground Fault LED

System Reset LED

The amber Walk Test indicator illuminates steadily to indicate that the panel is in walk test mode. If

the panel is left in this mode for over an hour with no operator activity, the panel will return to normal

and the Walk Test indicator will turn OFF.

The CPU Fail LED flashes amber at the trouble flash rate to indicate a microprocessor failure on the

main board.

The amber Auxiliary Disconnect LED flashes at the trouble rate when the Auxiliary Disconnect

button is pressed. It turns off when the Auxiliary Disconnect button is pressed a second time. When

on, the Auxiliary Disconnect LED signifies that auxiliary alarm relay and relay adder modules (if

disconnect is enabled) are not activated. If installed and enabled, the city tie module and the smart

relay annunciator relays are also inactive.

The Signal Silence indicator flashes amber at the trouble rate when indicating circuits are silenced

either by the Signal Silence button or by the Auto Signal Silence timer. It turns off when the signals

are re-sounded by a subsequent alarm or when the panel is reset.

The amber Battery Trouble LED flashes at the trouble rate when the battery is either low or

disconnected.

The amber Ground Fault LED flashes at the trouble rate when the ground fault detector detects a

ground fault on any field wiring. It turns off when the ground fault is cleared.

The amber System Reset LED illuminates for a short time when the System Reset button is

pressed.
