Installation Instructions Model ABHW-4SZ Intelligent Audible Base for Sleeping Area with 520Hz Low Frequency Sounder Introduction The Model ABHW-4SZ audible base from Siemens Industry, Inc. is an intelligent supervised base which is designed for use in sleeping areas. The base generates a 520Hz square wave audio signal complying with the latest NFPA 72 standard and is UL/ULC listed. It provides six selectable tone patterns, two volume levels when used with compatible fire detectors and control panels.
Specifications Physical Specifications: Operating temperature: 32°F ~ 120°F (0°C ~ 49°C) Operating humidity:10 ~ 95%RH (Non Condensing) Compatible electrical mounting boxes: 4” square gang box ONLY with 2.

XLS/Desigo Fire Safety Modular/Cerberus PRO Modular zone indicating card (NAC), refer to Figure 3), PAD-3/ PAD4/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.
Detector wiring (Refer to Figures 7 and 8) Audible base Model ABHW-4SZ should be interconnected as shown in the Installation/ Wiring Diagrams and wired to the specific system modules and control panels following the appropriate instructions.
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.
