Siemens ABHW-4B Sounder Base, Installation Instructions

Instructions ABHW 4B Audible Base Model ABHW 4B audible base from Siemens Industry consists of a standard base combined with an audible It is an intelligent supervised audible base which 6 selectable tone patterns 2 volume levels and 2 power types for alarm loop power or external power using system configuration tool when ABHW 4B used with FD UL compatible detectors refer to fire control panels detector and and Volume Selection The ABHW 4B bases in the same device loop are fully synchronized FD UL detectors and also support RL HC RL HW remote The ABHW 4B provides Steady Temporal 3 Temporal Temporal 4 low power March time 120 and Canadian time 30 is fully compatible with all Siemens addressable see Compatible detectors section and recognizes detector type automatically ABHW 4B is a UL268 ULC S529 listed smoke detector device which combines detector base and device functions It meets or exceeds 85 dB at 10 foot requirement as specified in UL268 When used in with listed compatible Siemens equipment the may be used in lieu of single multiple station smoke to achieve enhanced system level functionality ABHW 4B can also meet requirement specified in UL464 and ULC 525 except 520 Hz

RMS max Loop powered High dBA dBA powered High dBA Low dBA mA mA mA mA If the alarm current of ABHW 4B is energized by an external supply any UL listed 24 VDC regulated power supply the aux power output of XLS Desigo Fire Safety PRO Modular FC2005 FC901 and PAD 3 PAD 4 PAD 5 can used refer to Figure 3 or a 24 VDC NAC such as PAD refer to Figure 6 ZIC 4A FireFinder XLS Fire Safety Modular Cerberus PRO Modular zone card NAC refer to Figure 5 and NAC from refer to Figure 7.1 NAC from FC2025 FC2050 FV2025 FV2050 FC922 refer to Figure 7.2 The alarm current of ABHW 4B CANNOT be energized by a V FWR power supply The maximum number of ABHW 4B is related to the max rating and the power line resistance of the external supplies applied on the ABHW 4B Refer to the related instructions of the auxiliary power supply Refer to Figure 1 for Powered The maximum number powered ABHW 4B is limited by the max load and devices loaded in loop Refer to APPENDIX A this document to calculate the max number of ABHW 4B audible bases The maximum device line resistance cannot exceed the device line resistance specified in the compatible 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 4B must be configured by the panel when it is with FD UL detectors see table 1 Failure to the ABHW 4B 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 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 to Figure 8,9 Audible base Model ABHW 4B should be as shown in the Installation Wiring Diagrams wired to the specific system modules and control panels the appropriate instructions For operation with Desigo Fire Safety Modular Cerberus PRO FC2005 FC901 FC2025 FC2050 FV2025 FV2050 system note any limitations on number of audible bases permitted on each notification circuit or 24 VDC regulated power supply on the total cable resistance and load of each See Electronic 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 4B audible base using the four position blocks 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 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 In all installations in special circumstances like computer room under locate the detector on the ceiling a minimum of inches from a side wall or on a wall between 4 and 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 smooth beamed Siemens Industry Inc s extensive experience in design of fire detection systems assures optimum detector and is reflected in these drawings Follow sound judgment made by qualified personnel fire alarm control panels Type Fire Safety 50 point panel PRO 50 point FACP 250 500 point Fire
