Speaker Base_Four-Wire System (L300AVBS)

Product Overview

The L300AVBS sound base is one of the detector products independently developed by Ningbo Jinchun Intelligent Technology Co., Ltd. This product is mainly used in fire alarm control systems. The L300AVBS model is used in intelligent alarm systems, and the maximum number allowed per network can be referred to in the controller panel's user manual. The L300AVBS requires an external 24VDC power supply and can be wired with reverse polarity. To prevent circuit interference, the external power circuit (24V+ and 24V-) is isolated from the communication line circuit (LA and LB). When the LED on the detector locks and stays lit for about 0.5 seconds, the sound device on the connected base starts to emit sound.

Note: If this sound base is not used as a sound warning system, the external 24VDC power supply can be treated as a main power supply device and must comply with the requirements of the main power supply system.
