Installation Instructions
Model SZE-4X
Zone/Output Expander Module
Mounting the SZE-4X (Refer to Figure 1):
Install the Main Board of the SXL-EX or SXL-EX-INT
(See the SXL-EX Operation, Installation, and Mainte-
nance Manual, P/N 315-095997). Then install the
SZE-4X in the lower portion of the EN-SX enclosure
by following the steps listed below.
1. Screw the four standoffs onto the four studs
located in the lower portion of the SXL-EX
enclosure.
2. Place the SZE-4X over the four standoffs. Using
the four screws provided, fasten the SZE-4X
board to the standoffs.
Wiring
See Figure 2 for wiring connections from the SZE-4X
to the SXL-EX Main Board.
PROGRAMMING
Refer to the SXL-EX Operation, Installation, and
Maintenace Manual (P/N 315-095997) for program-
ming instructions related to IDC Zones, and Open
Collector and Relay Outputs.
OPERATION
The Model SZE-4X Zone/Output Expander module
from Siemens Industry, Inc., is used with the SXL-EX
to provide an additional four Class B (Style B) Initiating
Device Circuits, four Form C Relays, and four Open
Collector Output Circuits. All the devices on these
circuits are user programmable. Each inititiating
device circuit can drive up to 30 conventional type
detectors and an unlimited number of shorting type
devices. The SZE-4X can also be used with the
SXL-EX-INT.
ELECTRICAL CHARACTERISTICS
Supervisory: 41mA at 24 VDC
Alarm: 510mA at 24 VDC
Each IDC 120mA at 24 VDC
Each Relay 26mA at 24 VDC
INITIATING DEVICES
Each SZE-4X IDC Zone can connect to the initiating
devices indicated below:
1. Up to 30 smoke detectors may be used on an
SZE-4X zone. Compatible detectors are listed in
Table 1. Detectors of different models are not to
be mixed or matched on a system.
2. The PBA-1191 Beam Detector may be used as
shown in Figure 4. Only one PBA-1191 Beam
Detector may be used on an SZE-4X zone and
eight total on the system.
3. Any number of shorting type devices can be used
on a SZE-4X zone.
Refer to Figures 2, 3, and 4 for the wiring of the
detectors, shorting type devices, and the beam
detector devices.
INSTALLATION
Remove all system power before
installation, first battery and then AC.
(To power up, connect the AC first, then the battery.)

NOTES:
1. The SXL-EX Control Panel meets NFPA 72
Local requirements.
2. All field wiring must be in accordance with
NFPA 70, Article 760.
3. Do not make any wiring connections
while the System is powered.
4. Form C relay contacts are shown de-
energized. They are not suitable for motor
or pilot duty.
5. Combined current output for NAC1, NAC2,
and auxiliary outputs is limited to 3.0 amps.
6. Equipment connected to these terminals
must be located within the same room.
7. In all cases the Siemens Industry, Inc.,
Model Number is the compatibility
identifier, including the Control Panel,
Module(s), and all Compatible Initiating
Devices.
