Model 4720 Control/Communicator Installation Manual (P/N 150476, Rev. A) Revised 10/98
15.1 LED Indications
15.1.1 LEDs on Left Side (Behind Door)
Armed LED
ON – The system is armed.
OFF – The system is disarmed.
FLASHING – One or more zones are in an alarm condition.
No Delay LED
ON – Zones that were programmed as delayed will now act as instant zones, with no delay
before generating an alarm.
OFF – Exit and entry delayed zones will work as programmed.
Interior LED
ON – All zones will be armed when the Armed light is ON.
OFF – Interior zones are disabled. When the Model 4720 is armed, it protects the building
against entry from the outside, but people can move around inside without setting off the
alarm.
Chime LED
ON – The 4720 is disarmed and the Chime feature is enabled. When anyone enters the
protected area via a zone programmed as a chime zone, a chime zone will sound.
OFF – SYSTEM DISARMED – The Chime feature is disabled. NO tone will sound when
anyone enters the protected area.
SYSTEM ARMED – When the system is armed, violating a zone will cause an alarm, NOT a
chime tone.
Ready LED
ON – The system is disarmed and all enabled zones are ready to be armed. (Zones that are
disabled have either been bypassed, or they are interior zones that have been turned off.)
OFF – This has two meanings:
SYSTEM DISARMED – One or more zones are in a Not Ready condition. A
sensored door or window may be open. The zone(s) that are in a not ready condition
will be indicated by the Zone LEDs.
SYSTEM ARMED – System is in normal operating condition.
FLASHING – The 4720 is reporting to the central station.
