Standard Components
A standard four zone SXL-EX has one
modulethe main board. An expander board
is added to provide four additional zones,
when needed.
MAIN BOARD
The Main board of the SXL-EX or SXL-EX-INT
contains the intelligence for the system and
performs all of the input/output processing as
listed below:
Two supervised Notification Appliance
Circuits provide 2 VDC at 1.5 amps.
Each circuit operates Class B (Style Y)
and can be independently programmed
to operate a number of different ways
(Non-Coded, March Time, Temporal, or
Simple Zone Code).
Two Form C relays rated at 30 VDC at 1
amp resistive, 30 VAC at 500mA resis-
tive. These relays are for Alarm and
Trouble operation.
 A dual mode battery charger that
provides float and constant current

modes of charging sealed lead acid
batteries (15 Amp-Hour maximum).
Nonvolatile storage of system con-
figuration so that configuration remains
intact during loss of system power.
Four supervised power limiting
Initiating Device Circuits Each circuit
operates Class B (Style B) and can be
independently programmed to operate as
an Automatic Alarm input, a Verified
Alarm input, a Supervisory input, or a
Generic input. Each initiating device
circuit can use an unlimited number of
manual shorting-type devices.

The Function Keys
The ACK key is used to acknowledge alarms,
troubles, and supervisory conditions. In general
the LEDs change rom pulsing to steady to
indicate that the condition was acknowledged.
The SILENCE key silences the noti ication
appliance circuits that are con igured as
silenceable. Pressing the SILENCE key a
second time causes the NACs to re-sound.
The RESET key resets the SXL and all o the
smoke detectors.
The DRILL key activates all o the noti ication
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 o the status o 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 rom batteries.
The red Alar 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 o the trouble and supervisory
conditions are di erent.
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 o the
trouble and supervisory conditions are di erent.
The yellow Bypass/Alar Silence LED is on
steady when a zone in the system is bypassed
and it pulses when a noti ication circuit is silenced.
When an initiating device zone is bypassed, the
appropriate yellow zone trouble LED is on.
The Test/Progra 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 seg ent 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
ollowing chart.
