Installation Instructions

Model XLD-1
Analog Loop Driver

OPERATION

The Model XLD-1 from Siemens Building Technolo­gies, Inc. is an optional MXL network module that
connects XL3 analog addressable devices to the
MXL System. The module uses four consecutive
network addresses on the System. Devices
connected to the XLD-1 circuits are supervised by
the MXL Control Panel.

Each of the XLD-1 circuits supports up to 30
alarm causing, trouble causing, and supervisory
type devices, as well as intelligent output de­vices. Each device has its own address. The
sensitivity of any analog smoke detector is
checked and adjusted from the Control Panel.
Sensitivity, as well as other device information, is
displayed at the Control Panel. The XLD-1 also
supports the use of relay bases.

Each XLD-1 circuit can be wired in either a Class B
or Class A configuration. When using Class B, T­tapping is permitted with no loss of supervision.

The XLD-1 module has an on-board micro­processor which provides it with the ability to
function and to initiate alarm conditions even if the

Fire Safety

MXL main processor fails. The module also has
four LEDS, which can indicate alarm, trouble,
transmit, or ground fault. (Refer to Figure 1.)

For additional information on the MXL/MXLV
System, refer to the MXL/MXLV Manual, P/N

315-092036.

INSTALLATION

Remove all system power before installa­tion, first battery and then AC. (To power up,

connect the AC first and then the battery.)

The XLD-1 installs into the MXL optional MOM-4
card cage where it plugs into one full width slot.
The XLD-1 can be installed in either of the full
width slots of the MOM-4 (See Figure 2). The slot
determines whether the device loops are avail­able on TB1 or TB2 of the MOM-4.

Before installing the XLD-1 in the MOM-4, set the
network address using switch S1 (Refer to Figure
1 for the location of S1). Set it to the lowest of the
four corresponding addresses selected for it in the
CSG-M. (The lowest address may be odd or

NOTE: To open a dipswitch, press down on the side
of the dipswitch marked OPEN. To close a dipswitch,
press down on the side of the dipswitch opposite the
side marked OPEN.

To open a slide switch, push the slide to the
side opposite the side marked ON. To close a slide
switch, push the slide to the side marked ON.

After the address is set, install the XLD-1 in the
MOM-4, being sure that the module is riding in
the card guides and is firmly seated in the card
edge connector. Eliminate all troubles from each
XLD-1 before installing the next one.

Electrical connections for the four addressable
initiating zones are shown in Figure 3.

Compatible Devices

1. All circuits are power limited to NFPA 70 per
Article 760. Each detector or group of
detectors must use a 2-wire circuit of at least
18 AWG thermoplastic fixture wire enclosed
in conduit, or 18 AWG limited energy shielded
cable without conduit, if permitted by local
building codes.

2. No end of line device is required for these
initiating loops.

3. Up to 30 devices can be used per loop. See
the Compatibility Table for the XLD-1 for a
list of compatible devices. Use any combi­nation of those listed.

4.

The compatibility identifiers for the compatible
devices are the model numbers listed in the

Compatibility Table

5. Total circuit resistance must not exceed 100
ohms.
Maximum capacitance:

0.4uF, between loop+ and loop–

0.8uF, between loop+ and chassis

0.8uF, between loop– and chassis

6. T-tapping is not allowed on Class A loops.
