Understanding the Lights (LEDs)
Zone LEDs
If off , the zone is normal.
If on , a sensor in the zone detects a
problem. (The zone is said to be faulted.)
If blinking fast , a sensor in the zone is
signaling an alarm, or the zone's sensor
has been tampered with.
If blinking slowly , the zone is bypassed.
If blinking unevenly , a sensor in the zone
may need service. (This is called a
trouble zone.)
Power LED
If on , the system's power
supply is normal.
If off , the keypad is drawing
power from the battery.
If blinking slowly , the battery
is low (call for service).
Service LED
If on , a system
component is
malfunctioning and
may need service.
If off , all system
components are
normal.
Arm LED
If on , the system is armed.
If off , the system is disarmed.
If blinking fast, the system is
about to arm; leave the building.
If blinking slowly , you have time to
cancel an alarm, before it
sounds.
If blinking unevenly , system is
armed with instant arming.
Your keypad has a number of LEDs that summarize the status of
your security system. Each LED can convey several different mes-
sages by being on, off, or blinking. The illustration shows what
messages the lights communicate.
LED Blink Rates
Slow: light blinks twice every three seconds
Fast: light blinks three times every two seconds
Uneven: light blinks for three seconds, then pauses for two seconds
Ready LED
If on , the system can
be armed.
If off , a problem exists
which may prevent
arming.
If all of the
LEDs are
blinking,
enter your
user code.
