D250-04-00 4 I56-2813-002R ©2007 System Sensor System Sensor warrants its enclosed smoke detector base to be free from defects in mate- rials and workmanship under normal use and service for a period of three years from date of manufacture. System Sensor makes no other express warranty for this smoke detector base. No agent, representative, dealer, or employee of the Company has the authority to increase or alter the obligations or limitations of this Warranty. The Company’s obligation of this Warranty shall be limited to the repair or replacement of any part of the smoke detector base which is found to be defective in materials or workmanship under normal use and service during the three year period commencing with the date of manufacture.

Copies of this manual are available from System Sensor. NFPA 72 and NEMA guidelines should be observed. NOTICE: This manual should be left with the owner/user of this equipment. IMPORTANT: The detector used with this base must be tested and maintained regularly following NFPA 72 requirements. The detector should be cleaned at least once a year. General Description The B501BH-2 sounder base is used with System Sensor 200 Series sensor heads. Refer to the appropriate manual for more information on sensors. The sounder base is intended for use with intelligent systems. Refer to the panel manual for the maximum allowable num- ber of units per loop. The sounder base requires an external 24VDC supply with reverse polarity capability or a relay mod- ule configured to reverse the power as in Figure 5. The con- nections for the external supply (terminals 1 and 2) and the communication loop (terminals 3 and 4) are isolated to pre- vent electrical interaction between them. A loop of horns can be made to sound by reversing the polar- ity of the external supply when configured as in Figure 4 and 5. When configured as in Figure 5, a loop of horns can also be made to sound by turning on the Intelligent Relay Module. NOTE: When not used as a supplementary evacuation system the external 24 VDC supply shall be treated as a component of the main power supply system and shall fall under the require- ments of the main power supply system per NFPA 72.

Line In and Out 5 Sounder Base Interconnect Terminals 3 and 4 are used for the communication circuit. Mounting Mount the B501BH-2 directly to an electrical box, using the mounting kit, supplied (see Figure 2). The sounder base is 1.1-inches deep. Electrical boxes must be 4-inches square by at least 11⁄2 inches deep - 21⁄8 inches is rec- ommended. NOTE: A maximum space of 1⁄8 inch from the outside edge of the electrical box to the inside edge of the drywall or ceiling tile is allowable. Wiring Guidelines All wiring must be installed in compliance with the National Electrical Code and the local codes having jurisdiction and must not be of such length or wire size which would cause the base to operate outside of its published specifications. The conductors used to connect smoke sensors to control panels and accessory devices should be color coded to reduce the likelihood of wiring errors. Improper connections can prevent a system from responding properly in the event of a fire. For signal wiring (the wiring between interconnected sensors or modules), it is recommended that the wire be no smaller than 18 gauge (1.0 square mm). Wire sizes up to 12 gauge (2.5 square mm) may be used with the base. For best system per- formance, the power (+ and –) wires and the communication THREE-YEAR LIMITED WARRANTY Department, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please include a note describing the malfunction and suspected cause of failure. The Company shall not be obligated to repair or replace units which are found to be defective because of damage, unreasonable use, modifications, or alterations occurring after the date of manufacture. In no case shall the Company be liable for any consequential or incidental damages for breach of this or any other Warranty, expressed or implied whatsoever, even if the loss or damage is caused by the Company’s negligence or fault. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This Warranty gives you specific legal rights, and you may also have other rights which vary from state to state. Please refer to insert for the Limitations of Fire Alarm Systems I56-2813-002R
