OPERATION
The Model ALD-2I from Siemens Industry, Inc.
is an optional MXL/MXLV/MXL-IQ network
module that connects intelligent addressable
devices to the MXL/MXLV/MXL-IQ System.
The module uses two consecutive network
addresses on the System. Devices connected
to the ALD-2I circuits are supervised by the
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
B or Class A configuration. When using Class B,
T-tapping is permitted with no loss of supervision.
The ALD-2I module has an on-board micro-
processor 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.)
