User Guide
General Information
The D279A Independent Zone Control is an arming station that
provides you with control over a specified area of your security
system. The D279A gives you independent control of this area,
regardless of whether the rest of your security system is armed
or disarmed. Features of the D279A include protection status
display indicators, entry and exit delay time, prewarning sounder,
individual zone annunciation, panic alert, and a user-program-
mable passcode.
The Zone Control Display
The Zone Control has three protection status display indicators:
a DELAYED loop indicator, an INSTANT loop indicator, and an
ARMED indicator.
DELAYED
- When this green indicator is lit, the delay area is
ready to be armed. When 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).
INSTANT
- When this green indicator is lit, the instant area is
ready 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 INSTANT indicators
must be lit before arming.
