The Function Keys
The ACK key is used to acknowledge alarms,
troubles, and supervisory conditions. In general
the LEDs change from pulsing to steady to
indicate that the condition was acknowledged.
The SILENCE key silences the notification
appliance circuits that are configured as
silenceable. Pressing the SILENCE key a
second time causes the NACs to re-sound.
The RESET key resets the SXL and all of the
smoke detectors.
The DRILL key activates all of the notification
appliance circuits.
The yellow zone status LEDs indicate
a trouble or supervisory condition existing on a
particular input. Pulsing indicates the condition
was not acknowledged; on steady indicates it
was acknowledged.
The red zone status LEDs provide an
indication of the status of a particular zone.
Pulsing indicates an alarm condition in that
zone. When the alarm is acknowledged, the LED
remains on steady until the panel is reset.
FRONT PANEL FUNCTIONS
The front panel of the SXL-EX is comprised of
a seven segment display, function keys, and
LEDs. Their functions are described below
(Refer to Figure 2):
The LEDs
The green Power LED remains on steady when
AC power is connected and pulses when the unit
is operating from batteries.
The red
Alarm LED pulses when an alarm is
detected until it is acknowledged. Then it remains
on steady until the alarm condition is reset.
The yellow
Supervisory LED pulses when a
supervisory condition is detected until it is ac-
knowledged. Then it remains on steady until the
supervisory condition is reset. Note that the
pulsing rates of the trouble and supervisory
conditions are different.
The yellow
Trouble LED pulses when a trouble
condition is detected until it is acknowledged.
Then it remains on steady until the trouble condi-
tion is reset. Note that the pulsing rates of the
trouble and supervisory conditions are different.
The yellow
Bypass/Alarm Silence LED is on
steady when a zone in the system is bypassed
and it pulses when a notification circuit is silenced.
When an initiating device zone is bypassed, the
appropriate yellow zone trouble LED is on.
The
Test/Program LED is on steady when the
Test mode is selected and it pulses when the
Program mode is selected.
The Sounder
CONDITION RATE OF PULSATION
SYSTEM ALARM Sounds steady
TROUBLE Pulses at 50% duty cycle
SUPERVISORY Pulses at 25% duty cycle
CPU FAILURE Pulses once every 2 seconds
The seven segment display indicates
the various system troubles and the programming
and test modes. The numbers and symbols that
appear on this display are described in the
following chart.
