The Siemens ABHW-4B Audible Detector Base P/N: S54320-F13-A1 is an intelligent supervised sounder base designed for compatible Siemens addressable fire detectors. It combines a standard detector mounting base with an integrated audible signaling device for localized fire and emergency notification.
The ABHW-4B supports both SLC loop-powered two-wire operation and externally powered operation. Siemens currently lists S54320-F13-A1 as an active product within its detector-base family.
The ABHW-4B combines a detector base with an integral audible signaling device.
When used with compatible Siemens detectors and fire alarm control equipment, the sounder can be activated according to system programming. Multiple ABHW-4B bases on the same compatible device loop can operate in synchronization.
The base produces a standard high-frequency audible signal suitable for localized fire and emergency notification.
The ABHW-4B provides six configurable audible patterns:
Steady
March Time 120
Canadian March Time 30.
This allows the same base to support different fire and emergency signaling requirements through compatible system programming.
The ABHW-4B supports both fire and carbon-monoxide signaling patterns.
Temporal 3: Common standardized fire evacuation pattern
Temporal 4: Carbon monoxide notification pattern
The availability of both patterns allows compatible systems to use the audible base for multiple emergency signaling functions.
The audible base provides two programmable output levels:
High: approximately 85 dBA at 10 ft
Low: approximately 75 dBA at 10 ft
This allows the audible output to be configured according to the protected area’s requirements.
A key feature of the ABHW-4B is its loop-power capability.
When used with compatible Siemens equipment, the base can receive operating power directly from the signaling line circuit, providing a two-wire arrangement without requiring a separate notification power circuit.
The base can alternatively operate from an external regulated 24VDC source when required by the system configuration.
Siemens documents compatibility with H-Series and S-Series detectors including:
HFP-11 — Optical/Heat Detector
HFPT-11 — Heat Detector
HFPO-11 — Optical Detector
SFP-11 — Optical/Heat Detector
SFPT-11 — Heat Detector
SFPO-11 — Optical Detector.
Additional Siemens detector families may also be compatible depending on the control panel and system configuration.
The ABHW-4B supports compatible Siemens remote alarm indicators including:
RL-HC — Ceiling-mounted Remote Alarm Indicator
RL-HW — Wall-mounted Remote Alarm Indicator.
These accessories allow detector alarm indication to be displayed at another visible location when required.
