SIEMENS ABHW-4S Intelligent Audible Base for Sleeping Area Instruction Manual

SIEMENS ABHW-4S Intelligent Audible Base for Sleeping Area ****

Installation Instructions

Introduction

The Model ABHW-4S audible base from Siemens Industry, Inc. is an intelligent supervised base which is designed for use in sleeping areas. The base generates a 520 Hz 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. The ABHW-4S audible bases wired in the same device loop are fully synchronized with FD-UL detectors and also support RL-HC, RL-HW remote lamps. The ABHW4S provides 520 Hz Steady, Temporal 3, Temporal 4, Temporal 4 low power, March time 120 and Canadian March time 30. ABHW-4S is fully compatible with all Siemens addressable detectors and recognizes the detector type automatically. (Refer to the list of compatible detectors and control panels in this document).

Application note

The ABHW-4S is a UL & ULC listed smoke detector supplementary device. It meets or exceeds 85 dB at 10-foot audibility requirement as specified in UL268 & ULC-S529. When used in conjunction with listed, compatible Siemens equipment, the ABHW-4S may be used in lieu of single/multiple station smoke alarms to achieve enhanced, system-level functionality. The ABHW-4S can also meets the requirements specified in UL464, UL2075 including 520 Hz low frequency requirements for “Sleeping Area”.

Constraints

1. The alarm current of ABHW-4S has to be energized by any UL listed 24 VDC regulated auxiliary power supply including the aux power output of XLS/Desigo Fire Safety Modular/Cerberus PRO Modular, FC2005/FC901, FC2025/ FC2050/FV2025/FV2050, FC922/FC924/FV922/FV924 and PAD-3/PAD-4/PAD-5 (refer to Figure 1), ZIC-4A (FireFinder- 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 24 VDC 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-4S CANNOT be energized by a 24 V FWR power supply.
3. The maximum number of ABHW-4S is related to the maximum current rating and the power line resistance of the auxiliary power supplies applied on the ABHW-4S. Refer to the related installation instructions of the auxiliary power supply.
4. The maximum loop line resistance cannot exceed the maximum line resistance defined in the compatible fire control panels.
5. T-tapping of the notification appliance circuit is not allowed.
6. The NAC output must be set to a steady DC if it is used for ABHW-4S.

Configuration Important!

The ABHW-4S must be configured by the panel when it is connected with FD-UL detectors (see Table 1). Failure to configure the ABHW-4S 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.

Detector wiring

(Refer to Figures 7 and 8) Audible base Model ABHW-4S 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/Desigo Fire Safety Modular/Cerberus PRO Modular, 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 24 VDC regulated power supply, depending on the total cable resistance and total load of each circuit. (See ELECTRICAL RATINGS section.)
Note: Recommended wire size: 18 AWG min.; 14 AWG max.
Wire larger than 14 AWG can damage the connector.

Detector mounting

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

Base 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-4S loop continuity check, refer to the DPU or SDPU Manual, “Testing a FireFinder-XLS Loop”.
5. If loop continuity is acceptable, proceed with detector head installation.
   Use a 30-foot center spacing (900 sq ft), as a starting point referred to in NFPA Standard 72 National Fire Alarm Code and CAN/ULC-S524, 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 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.
