Installation Instructions

3
PAD-3/PAD-4/PAD-5 (refer to Figure 1), ZIC-4A (FireFinder-
XLS/Desigo Fire Safety Modular/Cerberus PRO Modular
zone indicating card (NAC), refer to Figure 3), PAD-3/ PAD-
4/PAD-5 (Figure 4), or a 24VDC NAC circuit such as
FC2005/ FC901 (Refer to Figure 5.1) or NAC circuit such as
FC2025/FC2050/FV2025/FV2050, FC922/FC924/FV922/
FV924 (Refer to Figure 5.2).
2. The alarm current of ABHW-4SZ CANNOT be energized by
a 24V FWR power supply.
3. The maximum number of ABHW-4SZ is related to the
maximum current rating and the power line resistance of the
auxiliary power supplies applied on the ABHW-4SZ. Refer to
the related installation instructions of the auxiliary power
supply.
4. The maximum loop line resistance cannot exceed the
maximum line resistance defined in the compatible fire
control panels.
5. T-tapping of the notification appliance circuit is not allowed.
6. The NAC output must be set to a steady DC if it is used for
ABHW-4SZ.
Configuration
Important!
The ABHW-4SZ must be configured by the panel when it is
connected with FD-UL detectors (see Table 1). Failure to
configure the ABHW-4SZ will cause problems. For additional
information please refer to the manual of related panel. Also, for
use with H-Series detectors (see Table 2) it does not require
panel configuration as it will function the same as an ADBH-11
which will not be synchronized.
