Configuration
Important!
FC2005/FC901 (refer to Figure 4.1)
or NAC from FC2025/FC2050/FV2025/FV2050, FC922/
FC924/FV922/FV924 (refer to Figure 4.2).
2. The alarm current of ABHW-4BZ CAN'T be energized by a
24V FWR power supply.
3. The maximum number of ABHW-4BZ is related to the max.
current rating and the power line resistance of the external
power supplies applied on the ABHW-4BZ. Refer to the
related installation instructions of the auxiliary power supply.
4. Refer to Figure 5 for "Loop Powered". The maximum number
of "loop powered" ABHW-4BZ is limited by the max. load
capacity and devices loaded in loop. Refer to APPENDIX-A
in this document to calculate the max. number of "loop
powered" ABHW-4BZ audible bases.
5. The maximum device line resistance cannot exceed the
maximum device line resistance specified in the compatible
panels.
6. T-tapping of the notification appliance circuit is not allowed.
7. The NAC output must be set to a steady DC if it is used for
ABHW-4BZ.
The ABHW-4BZ must be configured by the panel when it is
connected with FD-UL detectors (see table 1). Failure to
configure the ABHW-4BZ 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.
