Model ABHW-4BZ

Intelligent Audible Base

Introduction

The Model ABHW-4BZ audible base from Siemens Industry,
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 ABHW­4BZ 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.

Application
note

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”.

Constraints

1. If the alarm current of ABHW-4BZ is energized by an

external power supply, any UL listed 24VDC regulated
power supply including the aux power output of XLS,
FC2005/FC901, FC2025/FC2050/FV2025/FV2050,
FC922/FC924/FV922/FV924 and PAD-3/PAD-4/PAD-5 can
be used (refer to Figure 1); or a 24VDC NAC, such as PAD­3/PAD-4/PAD-5 (refer to Figure 3), ZIC-4A (FireFinder-XLS
zone indicating card (NAC), refer to Figure 2) and NAC from

3

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.

C

onfiguration

Important!

The ABHW-4BZ must be configured by the panel whe n 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.

D

etector

wiring

(Refer to Figure 6,7) Audible base Model ABHW-4BZ should
be interconnected as shown in the Installation/Wiring
Diagrams and wired to the specific system modules and
control panels following the appropriate instructions. For
operation with FireFinder-XLS, FC2005/FC901,
FC2025/FC2050/FV2025/FV2050,
FC922/FC924/FV922/FV924 system, note any limitations on
the number of audible bases permitted on each notification
appliance circuit or 24VDC regulated power supply, depending
on the total cable resistance and load of each circuit. (See
Electronic Ratings section.)

Note: Recommended wire size: 18 AWG min.; 14 AWG max.
Wire larger than 14 AWG can damage the connector.

D

etector

mounting

The detector base comes from the factory prewired. All
signaling and initiating circuits are connected directly to the
back of the ABHW-4BZ audible base using the four position
terminal blocks.

B

ase

mounting

1. Route all wires out from the outlet box.

2. When the alarm LED viewing is critical, position the LED
mark on the base in the intended direction (Refer to Figure

8).

3. Make connections directly to the audible base terminals
located on the back of the base. Refer to the related
Installation/Wiring diagram.

4. After all bases are installed, check loop continuity. For
ABHW-4BZ loop continuity check, refer to the DPU or
SDPU Manual, “Testing a FireFinder-XLS”.

5. If loop continuity is acceptable, proceed with detector head
installation.

D

etector

placement

Even though no specific spacing are allocated to the detectors
used with this base, use 30 foot center spacing (900 sq ft), as
referred to in NFPA Standard 72 National Fire Alarm Code
and CAN/ULC-S524, as a guide or starting point, if practical,
in a detector installation layout. This spacing is based on ideal
conditions—smooth ceiling, no air movement, and no physical
obstructions. In all installations (except in special
circumstances like computer room under floors), locate the

detector on the ceiling, a minimum of 6 inches from a side

5

wall, or on a wall, between 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.
Environmental factors such as air current, temperature,
humidity, air pressure, and the nature of the fire load are
carefully considered. Special consideration is given to room or
area configuration and the type of ceiling (sloped or

flat, smooth

or beamed). Siemens Industry, Inc.'s extensive experience in
the design of fire detection systems assures optimum detector
placement and is reflected in these drawings. Follow sound
engineering judgment made by qualified personnel.

• DLC ver 06.01 or later

2. When the audible base ABHW-4BZ works with FD-UL series
detectors. Up to 6 tone patterns and 2 volume levels can be
selected by user with system configuration tool; there are
two power types for ABHW-4BZ during alarm, “Loop
Powered” and “External Powered” which can be configured
by system tool.

3. When the audible base ABHW-4BZ works with H-series
detector Only “External Powered” can be used. A fixed 85dB
tone is provided and only 2 tones can be selected (steady
and Temporal 3, refer to Figure 6): Ste ady: without a jumper
at terminals 3 and 4; Temporal 3: terminals 3 and 4 are
shorted with jumper.

4. When use “External Powered” for alarm, the ABHW-4BZ still
takes some power from loop during both supervision and
alarm status to keep it alive and external power is only for
the alarm current.

APPENDIX: Max. number of l oop pow ered ABHW-4BZ
audible bases in one loop

1. The max. number of loop powered ABHW-4BZ audible bases in one device
loop depends on the available load current for ABHW-4BZ audible bases. The
available load current for loop powered ABHW-4BZs (I) can be calculated by:
I = Imax – Id
In which, Imax is the max load current in one loop under the worst case
scenario with 50 Ω cable r esistance. I

d is the total load current for the

devices loaded in the loop.

Note: Loop power can’t be used for ABHW-4BZ with H-series detector
and the external power must be used.

3. How to calculate the max. number of loop powered ABHW-4BZ.

Step 1:

Calculate the total load current (Id) for the devices loaded in the device
line using the current rating of each device including accessories.
Example: Current load of 100 FDOT421 detectors = 0.25mA*100 = 25mA
Current load of 152 HFP-11 detectors = 0.75mA*152 = 114mA

Step 2:

Find out the max. device load current (I

max) of device line card at worst

case from the user manual of the panel.
Example: For DLC in XLS systems, 252 H-series devices can be
loaded at the end of 50 ohms max. line resistance (the worst case) and
max. load current is 252mA (I

max).

Step 3:

Find out the available load curr ent (I) for loop powered ABHW-4BZ
audible bases.
I = I

max – Id

Example: If 100 FDOT421 and 150 HFP-11 detectors loaded at the
end of 50 ohms cable, I=252–139 = 113mA

Step 4:

Find out the max. alarm current rating for the loop powered ABHW­4BZ (I

a). Find out the max. number of the loop powered ABHW-4BZ

using the charts above, or it is equal to (I/I

a).

Example: If all ABHW-4BZs are set to Low volume, the max. number of
loop powered ABHW-4BZs is 25 (from Figure 10). The max. current
rating of ABHW-4BZ is 4.5mA (from electronic ratings). The max.
number of loop powered ABHW-4BZs is equal to 113mA/4.5mA=25.
If all ABHW-4BZs are set to high volume, the max. number of loop
powered ABHW-4BZs is 15 (from Figure 9). The max. current rating of
ABHW-4BZ is 7.5mA. The max. number of loop powered ABHW-4BZs
is equal to 113mA/7.5mA=15.
