Siemens ABHW-4S Sounder Base

Instructions ABHW 4S Audible Base for Sleeping Area with 520Hz Frequency Sounder Model ABHW 4S audible base from Siemens Industry is an intelligent supervised base which is designed for use sleeping areas The base generates a 520 Hz square wave signal complying with the latest NFPA 72 standard and UL ULC listed It provides six selectable tone patterns two levels when used with compatible fire detectors and panels The ABHW 4S audible bases wired in the device loop are fully synchronized with FD UL detectors also support RL HC RL HW remote lamps The ABHW provides 520 Hz Steady Temporal 3 Temporal 4 4 low power March time 120 and Canadian March 30 is fully compatible with all Siemens addressable and recognizes the detector type automatically to the list of compatible detectors and control panels in document ABHW 4S is a UL ULC listed smoke detector device It meets or exceeds 85 dB at 10 foot requirement as specified in UL268 ULC S529 used in conjunction with listed compatible Siemens the ABHW 4S may be used in lieu of station smoke alarms to achieve enhanced functionality The ABHW 4S can also meets the specified in UL464 UL2075 including 520 Hz frequency requirements for

Safety PRO Modular FC2005 FC901 FC2025 FC922 FC924 FV922 FV924 and Fire Safety Modular Cerberus PRO Modular refer to Figure 1 ZIC 4A FireFinder indicating card NAC refer to Figure 3 PAD 3 PAD Figure 4 or a 24 VDC NAC circuit such as FC901 Refer to Figure 5.1 or NAC circuit such as FC922 FC924 FV922 The alarm current of ABHW 4S CANNOT be energized by a Refer to Figure 5.2 V FWR power supply The maximum number of ABHW 4S is related to the current rating and the power line resistance of the power supplies applied on the ABHW 4S Refer to related installation instructions of the auxiliary power The maximum loop line resistance cannot exceed the line resistance defined in the compatible fire panels T tapping of the notification appliance circuit is not allowed The NAC output must be set to a steady DC if it is used for ABHW 4S must be configured by the panel when it is with FD UL detectors see Table 1 Failure to the ABHW 4S will cause problems For additional please refer to the manual of related panel Also for with H Series detectors see Table 2 it does not require configuration as it will function the same as an ADBH 11 will not be synchronized to Figures 7 and 8 Audible base Model ABHW 4S be interconnected as shown in the Installation Wiring and wired to the specific system modules and control following the appropriate instructions For operation with Fire Safety Modular Cerberus PRO FC2005 FC901 FC2025 FC2050 FV2025 FC922 FC924 FV922 FV924 system note any on the number of audible bases permitted on each appliance circuit or 24 VDC regulated power supply on the total cable resistance and total load of each See ELECTRICAL RATINGS section Recommended wire size 18 AWG min 14 AWG max larger than 14 AWG can damage the connector detector base comes from the factory prewired All and initiating circuits are connected directly to the of the ABHW 4S audible base using the four position blocks Route all wires out from the outlet box When the alarm LED viewing is critical position the LED on the base in the intended direction Refer to Figure Make connections directly to the audible base terminals on the back of the base Refer to the related diagram After all bases are installed check loop continuity For loop continuity check refer to the DPU or SDPU a FireFinder XLS Loop If loop continuity is acceptable proceed with detector head a 30 foot center spacing 900 sq ft as a starting point to in NFPA Standard 72 National Fire Alarm Code CAN ULC S524 in a detector installation layout This is based on ideal conditions ceiling no air and no physical obstructions all installations except in special circumstances like room under floors locate the detector on the a minimum of 6 inches from a side wall or on a wall 4 and 6 inches from the ceiling questions arise regarding detector placement it is extremely that the drawings provided or approved by Siemens Inc or by its authorized distributors be followed The placements shown on these drawings were chosen a careful evaluation of all facets of protecting the area factors such as air current temperature air pressure and the nature of the fire load are considered Special consideration is given to room or configuration and the type of ceiling sloped or flat or beamed Siemens Industry Inc s extensive in the design of fire detection systems assures detector placement and is reflected in these
