The Model ALD-2I from Siemens Industry, Inc.
is an optional MXL/MXLV/MXL-IQ network
module that connects intelligent
devices to the MXL/MXLV
The module uses two consecutive networkaddresses on the System. Devices
to the ALD-2I circuits are supervised
MXL Control Panel.
Each of the ALD-2I circuits supports up to 60
alarm causing, trouble causing, security, and
supervisory type devices, as well as remote
CZM-1s and intelligent output devices. Each
device has its own address. The sensitivity of
any intelligent smoke detector is checked and

adjusted from the Control Panel. Sensitivity, as
well as other device information, is displayed at
the Control Panel. The ALD-2I also supports the
use of relay bases.
Each ALD-2I circuit can be wired in either a Class
or Class A configuration. When using Class B,
B
T-tapping is permitted with no loss of supervision.
The ALD-2I module has an on-board microprocessor which provides it with the ability to
function and to initiate alarm conditions even if
the MXL main processor fails. The module also
has four LEDs, which can indicate alarm, trouble,
transmit, or ground fault. (Refer to Figure 1.)

INSTALLATION
Remove all system power before installation,
first battery then AC. (To power up, connect the
AC first, then the battery.)
The ALD-2I installs into the MXL optional module
card cage, Model MOM-4. It plugs into one fullwidth slot in the MOM-4. The ALD-2I can be
placed in either the upper or lower slot of the
MOM-4 (See Figure 2). The position determines
whether the device loops are available on TB1 or
TB2 of the MOM-4.
If the MXL software revision level is 3.2 or higher,
cut jumper G2. If the level is below 3.2, do not
cut it.
For all MXL-IQ installations, cut jumper G2.
Before the ALD-2I is installed in the MOM-4, set
the network address using switch S1 (See Figure
1). Set it to the lower of the two corresponding
addresses selected for it in the CSG-M. (The
lower address must be odd.) Follow the appropriate switch positions in Table 1 on the back to set
the address.
The table below illustrates sample ALD-2I
module addresses:
After the address is set, install the ALD-2I 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
ALD-2I before installing the next one.
Electrical connections for the two addressable
initiating zones are shown in Figure 3.

1. All circuits are power limited to NFPA 70 per
NEC 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 60 detectors can be used per loop. See
the table at the right for a list of compatible
detectors. Use any combination of those
listed.
4.
The compatibility identifiers for the compatible
devices are the model numbers listed at the
right.
5. Total circuit resistance must not exceed 100
ohms.
Maximum capacitance:
0.4μF, between loop+ and loop–
0.8μF, between loop+ and chassis
0.8μF, between loop– and chassis
6. T-tapping is not allowed on Class A loops.
