Description
The ALD-2I is an MXL Network option module that supplies two intelligent
analog circuits utilizing Cerberus Pyrotronics “I” series type intelligent
devices. It occupies two addresses on the Network and, through the use of a
unique communications protocol, devices connected to the ALD-2I circuits are
dynamically supervised by the MXL Control Panel. Smoke detectors are monitored
for sensitivity and notification is given when the sensitivity is outside
normal parameters. Each of the ALD-2I circuits supports
the use of up to 60 alarm, trouble, security, status and supervisory type
devices as well as remote conventional initiating device zone modules (CZM-1)
and intelligent output devices (TRI-60R, ICP). Sensitivity of any smoke
detector can be queried and adjusted from the control panel. Sensitivity as
well as other device information can be displayed and printed at the control
panel. The ALD-2I supports the use of relay bases and audible bases
(independently controllable).
To provide analog loop short circuit isolation, the LIM-1 module can be used
to prevent a single short from interrupting loop device communication.
Each ALD-2I circuit can be wired in either a Style 4 (Class B) or Style 6
(Class A) configuration. When using the Style 4 method, T-Tapping is permitted
with no loss of supervision.
The ALD-2I has an on board microprocessor that provides it with the ability to
function in a degrade mode and initiate alarm conditions even if the MXL main
microprocessor fails.
The ALD-2I plugs into one full option slot in the MOM-2 or MOM-4 card cage.
This equipment is approved for operation over the temperature range of 0°C and
49°C.
Engineer and Architect Specifications
Intelligent analog device circuits shall be provided by an ALD-2I Analog Loop
Driver Module. This module shall plug into one full slot of the MOM-2 or MOM-4
card cage
as a part of the Cerberus Pyrotronics MXL or MXLV systems. Each ALD-2I shall
provide two circuits. Each of these circuits shall support the use of up to 60
intelligent devices, as well as remote conventional initiating zone modules.
Sensitivity of any smoke detector can be queried and adjusted from, as well as
displayed at, the control panel. Sensitivity change shall be performed either
manually or automatically through the time based logic.
The ALD-2I shall support the use of relay bases, audible bases, and remote
lamps.
ALD-2I circuits shall be capable of being wired to meet the requirements of
either NFPA Style 4 or Style 6. When wired as a Style 4 circuit, it shall
support the use of parallel branch circuits (T-Tapping).
The ALD-2I shall utilize an on board CPU as well as network interface
circuitry and A/D converters. It shall be capable of operation in a degrade
mode in the event of MXL main processor failure or loss or network
communication link. In the degrade mode the ALD-2I circuits shall be capable
of sensing an alarm condition from its connected devices and activating local
notification appliance circuits through a degrade alarm bus.
ALD-2I circuits shall meet the requirements of NEC 760 for power limiting.
