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 full-
width 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 appropri-
ate switch positions in Table 1 on the back to set
the address.

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.

Compatible Devices
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.
