FIREFINDER-XLS INSTALLATION, OPERATION AND MAINTENANCE MANUAL
The CC-2 provides a central point for
mounting up to two circuit card assem-
blies. If a card requires power, it is
applied through the removable terminal
block at the bottom of the cardcage. All
external devices for the card are
connected to the card through the two
removable terminal blocks at the top of
the cardcage.
The DLC supports one loop (two isolated parallel zones) of up to 252
FireFinder-XLS intelligent field devices as well as device accessories (relay
bases, audible bases, and remote lamps) in any combination. The DLC
initializes, operates, and maintains all devices residing on the loop and
communicates all relevant device and event information, such as alarms and
troubles, to the System CPU. The DLC allows the System polarity insensitive
devices to be connected without generating errors.
The microprocessor controls the on-board isolator to isolate either zone from
the loop if one of them is shorted. When one zone is isolated from the loop,
the other zone will still work.The on-board microprocessor provides the DLC
with the ability to function and initiate alarm conditions even if the main FireFinder-
XLS CPU fails.
The PTB filters the power from the incoming AC
mains and distributes it to the PSC-12 power supply
and the optional PSX-12 power supply extender.
circuits. It has 4 outputs that can be configured for Class A or Class B and
control of audible and visual notifcation appliances such as horns, speakers,
bells, strobes, etc. Its outputs can also be configured as connection to
Municipal Tie, Releasing Service per NFPA 12A, 13, and 2001 or as a connec-
tion to a Leased Line remote monitoring circuit.
Each zone can be configured independently for different usages as pro-
grammed 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.
Synchronization across multiple ZIC-4A cards is automatic as a part of the
FireFinder-XLS operating characteristics. Refer to document P/N 315-096363 for a list of
strobes that support synchronization.
