Zone Control Display

The Zone Control has three protection status displa y indicators: a DELAYED
loop indicator, an INST ANT loop indicator , and an ARMED indicator .

DELAYED - When this green indicator is lit, the delay area is re ady to be
armed. W hen the DELAYED indicator is not lit, the area is not ready to be
armed (check doors, windows, and motion detector vicinities in the delay
area).

INST ANT - W hen this green indicator is lit, the instant area is re ady to arm.
When the INSTANT indicator is not lit, the area is not ready to arm (check
doors, windows, and motion sensors in the instant area). Both the DELAYED
and INST ANT indicators must be lit before arming.

ARMED - The red ARMED indicator is lit when the area is armed and not lit
when the area is not armed. During exit delay (after the passcode is entered)
the ARMED indicator blinks. The indicator will not blink with alarm

memory.

Note: Both the DELAYED and INSTANT indicators must be lit before

arming.

Digital Keypad

The Zone Control has a digital keypad used to enter your passcode into the
security system. It is your passcode which arms and disarms the delayed and
instant areas.

When entering your passcode, if the Zone Control emits a short warning tone
each time you touch a key , check the DELAYED and INST ANT indicators.
Both LEDs should be lit. If either LED is NOT lit, check doors, windows, and

detector vicinities in the protected area.

Arming

1. Ensure that the area is secure. The green DELAYED and
INST ANT lights must be on.

2. Arm the area by entering your passcode.
The red ARMED indicator light flashes on and off to indicated

exit delay time (approximately 60 seconds). When the ARMED
indicator lights steadily, the delay and instant areas ar e armed.

Disarming

Disarm the area by entering your passcode.
When the area is armed, you must enter the premises through a designated

entry door to prevent an instant alarm condition. Opening the delay door
starts a 30-second delay during which the Zone Control sounds a warning to
remind you to disarm the system. To disarm the system, ente r y our personal
passcode before the entry time expires. If you enter through a wrong door, or
fail to disarm the system before the entry delay expires, you will generate an
alarm.

Note: If both the DELAYED and INSTANT loops are faulted at the end of

the exit delay, an entry delay will be initiated (not an instant alarm).
