FIREFINDER-XLS INSTALLATION, OPERATION AND MAINTENANCE MANUAL

MLC MXL Line Card

The MLC MXL line card loop driver allows MXL intelligent addressable
smoke detectors, manual stations, monitor devices, and control devices to
interface to the FireFinder-XLS System. The MLC uses two addresses on the
HNET network. The application program that is loaded into the on-board
microprocessor controls the MLC operation.

The MLC initializes, operates, and maintains all devices residing on the loop.
The MLC communicates all relevant device and event information, such as
alarms and troubles, to the System CPU. The sensitivity of any intelligent
smoke detector and the logic functions of any intelligent output devices can
be checked and adjusted from the PMI/PMI-2/PMI-3 through the MLC. All
information about the devices on the loop can be displayed on the PMI/PMI-
2/PMI-3.

The MLC supports two separate circuits. Each circuit can monitor and control up to
60 MXL intelligent field devices as well as device accessories (relay bases, audible
bases, and remote lamps) in any combination for a total of 120 devices per MLC. The
on-board microprocessor provides the MLC with the ability to function and initiate
alarm conditions even if the main FireFinder-XLS CPU fails.

PTB Power Termination

The PTB filters the power from the incoming AC

Board

mains and distributes it to the PSC-12 power supply
and the optional PSX-12 power supply extender.

ZIC-4A Zone Indicating Card The Model ZIC-4A is a zone indicating card that provides notification

appliance circuits. It has 4 outputs that can be configured for Class A or
Class B and control of audible and visual notification appliances such as
horns, speakers, bells, strobes, etc. Its outputs can also be configured as
connection to Municipal Tie, Releasing Service per NFPA 13, and 2001 or
as a connection to a Leased Line remote monitoring circuit.

Each zone can be configured independently for different usages as
programmed in the Zeus tool and can be controlled automatically by
program logic or manually using the PMI.

The ZIC-4A supports synchronized and non-synchronized strobes. This
selection is available in the Zeus tool under the detail properties for each
ZIC-4A circuit. Audible synchronization across multiple ZIC-4A cards is
automatic as a part of the FireFinder-XLS operating characteristics and
strobe synchronization is done on a card basis (strobe circuits within a
ZIC card). Refer to document P/N 315-096363 for a list of strobes that
support synchronization.

ZIC-8B Zone Indicating Card The Model ZIC-8B is a zone indicating card that provides notification

appliance circuits. It has 8 outputs that can be configured as Class B only
for control of audible and visual notification appliances such as horns,
speakers, bells, strobes, etc. Each zone can be configured independently
for different usages as programmed in the Zeus tool and can be controlled
automatically by program logic or manually using the PMI/PMI-2/PMI-3.
