Intelligent Audible Base
Introduction
Application
note
A6V10806895_en--_d
The Model ABHW-4BZ audible
Inc. consists of a standard base combined with an audible
device.
It is an intelligent supervised audible base which
provides 6 selectable tone patterns, 2 volume levels and 2
different power types for alarm (loop power or external power)
by using system configuration tool when ABHW-4BZ used with
the FD-UL compatible detectors (refer to "Compatible fire
alarm control panels", "Compatible detector ","Detector
Placement" and "Tone and Volume Selection"). The ABHW-
4BZ audible bases in the same device loop are fully
synchronized with FD-UL detectors and also support RL-HC,
RL-HW remote lamp. The ABHW-4BZ provides Steady,
Temporal 3, Temporal 4, Temporal 4 low power, March time
120 and Canadian March time 30.
ABHW-4BZ is fully compatible with all Siemens addressable
detectors (see Compatible detectors section) and recognizes
the detector type automatically.
The ABHW-4BZ is a UL268 & ULC-S529 listed smoke detector
supplementary device which combines detector base and
audible device functions. It meets or exceeds 85dB at 10 foot
audibility requirement as specified in UL268. When used in
conjunction with listed, compatible Siemens equipment, the
ABHW-4BZ may be used in lieu of single/multiple station smoke
alarms to achieve enhanced, system-level functionality.
The ABHW-4BZ can also meet requirement specified in UL464,
UL2075 and ULC-525 except 520Hz requirements for "Sleeping
Area".

- Page 4 The detector base comes from the factory prewired. All mounting signaling and initiating circuits are connected directly to the back of the ABHW-4BZ audible base using the four position terminal blocks. Base 1. Route all wires out from the outlet box.
- Page 5 4 and 6 inches from the ceiling. If questions arise regarding detector placement, it is extremely important that the drawings provided or approved by Siemens Industry, Inc., or by its authorized distributors be followed! The detector placements shown on these drawings were chosen after a careful evaluation of all facets of protecting the area.
