COMPATIBILITY
1.
The DLC supports only FireFinder-XLS/Desigo Fire Safety Modular/Cerberus
PRO Modular intelligent devices. The compatibility identifiers for the compat-
ible devices are the model numbers listed in Table 1 for UL 864 and in Table 2
for UL2572. Use any combination of those listed in Table 1 or Table 2, as
applicable.
2.
The DLC supports one loop (with 2 isolated zones) of up to 252 FireFinder-
XLS/Desigo Fire Safety Modular/Cerberus PRO Modular intelligent field
devices. Up to 252 devices can be distributed in either zone, but the total
number is limited. For example, if 100 devices are in Zone 1, then the
number of the devices in Zone 2 must be 152 or less.
3.
All circuits are power limited to NFPA 70 per NEC 760. The DLC supports
the use of 12-22 AWG non-shielded, non-twisted, thermoplastic fixture wire
without conduit, if permitted by local building codes.
4.
No end of line device is required.
5.
Total circuit resistance of each zone must not exceed 50 ohms when 252
devices are loaded into one zone. (Refer to the chart on page 7.)
Maximum capacitance:
0.5
μ
F between line+ and line-
1.0
μ
F between line and chassis
6.
T-tapping is not allowed on Class A loops.
7.
All models are UL and ULC listed.
8.
The Multi-Criteria detectors are programmed using the DPU. The SBGA-34
base, connected to a ZIC-4A, P/N 500-033050, or ZIC-8B, P/N 500-648670,
can be used to create Temporal 4 tones in conjunction with the Carbon
Monoxide enabled detectors FDOOTC441 and OOHC941. Using these
detectors with the ABHW-4S or ABHW-4B, the selection of tones are
chosen using the panel’s configuration tool.
The DLC circuit can be wired Style 4 (Class B) or Style 6 (Class A). On-board
switches controlled by microprocessor allow selection of Class A or B without using
jumpers for Class B. The DLC field circuit wiring does not require twisted, shielded
wire. It can be installed in conduit containing low voltage power, notification appli-
ance circuits, audible and speaker zone circuits, and RS-485 and other data circuits
without restrictions.
Electrical connections for the two zones are shown in Figure 4. The wiring style is set
in the Zeus Programming Tool without using external jumpers. Once the wiring style
is set, both zones will be set to the same style.
Do not wire the two zones in different styles.
If the return wires in either zone are reversed (in a Class A configuration), the CLASS
A RETURN LED associated with the affected zone will be illuminated. Switch the two
return wires to remove this trouble. Eliminate all other troubles before completing
the installation.
