System Overview

Model SXL-EX from Siemens ─ Fire Safety is a
microprocessor-based fire-alarm control panel (FACP)
supplied with four (4) conventional zones, and is
expandable to eight (8) conventional zones. Model
SXL-EX also contains features, such as: field
programmability; power-limited circuits, one-person
person test; remote annunciation, and sufficient
power to meet ADA requirements for signaling.

Model SXL-EX is designed to meet the varied fire­alarm needs for small office buildings, apartment
buildings, department stores, hotels, strip malls or
anywhere a cost-efficient, general-purpose FACP is
required.

Additionally, the SXL-EX can be used to supply remote
bell power for larger systems such as the MXL FACP.

Initiating Circuits

Model SXL-EX has four (4) conventional, Style B (Class
B) zones, which are typically compatible with the
ionization detector (Model DI-3*); the photoelectric
detector (Model PE-11*) and the photo-thermal
detector (Model PE-11T*); Siemens Fire Safety thermal,
flame and beam detectors, and the MS Series of
manual stations. (Please refer to the detector­compatibility list in the wiring diagram for specific
compatibility questions).

System Overview – (continued)

Any combination of 30 compatible smoke detectors can
be combined on a given zone. Any number of thermal
detectors, manual stations or other compatible direct
shorting devices may be connected to each zone. All of
these initiating devices can be mixed on the same zone,
providing the total power requirement of the zone does
not exceed 9mA supervisory current. Model SXL-EX has
the additional capacity to support detector accessories
such as: relays, remote alarm lamps and audible bases.

Initiating zones can be programmed for many
functions. Alarm verification allows detector
application in sensitive areas
manual stations
code. Manual station operation shall not be delayed
on verified zones. Generic zone function allows the
NACs in Model SXL-EX to follow the action of a
master fire-alarm panel in the facility.

Initiating zones can also be bypassed as required for
example during construction on the premises. The system
is expanded through the (4) four-zone expander (Model
SZE-4X), which has an additional four (4) initiating
circuits, in addition to relays and open-collector outputs.

─ mixed on the zone, as allowed by

Notification Appliance Circuits

Model SXL-EX has two (2) Style Y (Class B) NACs, each
rated at 1.5 Amps. The total power output of the panel,
between the two (2) notification circuits and the auxiliary
output, is limited to 3 Amps, which is sufficient to provide
power for many applications requiring appliances
designed to ADA specifications. The SXL-EX notification
circuits are power limited to reduce installation costs
without the addition of any hardware.

NACs can be programmed for various codes. These include:
temporal / march time, simplified zone code, and number of
rounds. They can also be inhibited during test and
programming functions.

The two (2) circuits can be individually programmed as
non-silenceable. This steady operation can be used for
strobes that must continue operation after audible
devices are silenced.

Relays and Outputs

Model SXL-EX has ‘Form C’ relays for general alarm and
trouble commands, rated at 1 Amp, 30VDC. The

optional (4) four-zone expander module (Model SZE-4X)
has an additional four (4) general purpose,
programmable relays at 2 Amps, 30VDC / 120VAC. All
remote operations in the fire-alarm system are
controlled from Model SZE-4X or the relay module
(SRC-8)
Model SXL-EX enclosure.

Model SXL-EX has visible LED annunciation by zone for

─ with or without

Additionally, there is a system alarm light-emitting diode
(LED) and a system trouble LED. Supervisory zones utilize
the zone trouble LED flashing in sync with a system
supervisory LED to indicate an abnormal system event.

LEDs for AC power bypass and test / program mode are
clustered with the system alarm, trouble and supervisory
LEDs. A (7) seven-segment display

annunciated by a piezo-electric sounder housed inside
Model SXL-EX.

Remote annunciation is accomplished through a serial
connection with Model LED-3 or Model LED-4, (8) eight­zone LED annunciators. Models LED-3 and LED-4 display
alarm, supervisory and trouble conditions for eight (8)
zones. A total of two (2) modules can be attached to
each system. Model LED-3 comes with a black
enclosure, while Model LED-4 uses a white enclosure.

─ used during testing

─ reports a code for each

Auxiliary Power

Model SXL-EX contains a 1/2 Amp auxiliary power circuit
that is used to drive remote devices. The total power for
Model SXL-EX, between the auxiliary output and the two (2)
NACs, is 3 Amps.

Power Supply / Battery Charger

The power supply accepts a 120VAC, 60 Hz. Input or,
optionally, a 220 / 240VAC, 50 Hz. Input. On loss of AC
power, the system switches to battery operation, indicating
a loss of power by flashing the AC power LED on the display.
Battery capacities of 24 and 60 hours are available.

Manual Controls

Model SXL-EX has four (4) switches for acknowledging
alarm, supervisory and trouble conditions; silencing NACs;
resetting the system, and for the drill function. These
switches are also used when programming the control unit.

Field Programmability and Test Functions

The following functions of Model SXL-EX are field
programmable, and are generally not programmed in the
unit, since the each unit is shipped ‘as received’ from the
factory. Field programming is accomplished through the
display, and does not require the use of a computer or any
proprietary tools.

Initiating Circuits:

─ Alarm Verification by Zone; Zone Bypass; Supervisory Zone,

or Generic Zone [when Model SXL-EX is used to provide
remote NACs]

Note: The default mode is an alarm-causing zone.

Notification Appliance Circuits:

─ Non-silenceable, Simple Zone Coding, March Time,

Temporal, Silence Inhibit, Cutoff Timers and Reminders

Note: The default mode is a steady signal.

The fire-alarm system shall have the following
features: subsequent alarm and trouble prompts; one
person test feature; brown out protection, and 24 or
60 hour battery backup. Model SXL-EX also has the
following selectable features: supervisory zones;
alarm verification by zone; non-latching zones; alarm,

trouble and supervisory history, NAC coding, alarm /
trouble 24-hour reminder, and zone / output bypass.

Any initiating-device circuit shall have the capability of
