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.
