Apollo Discovery 45681-393APO Sounder Beacon Base with Isolator (Red flash)
The Apollo Discovery 45681-393APO is a sounder visual indicator base with integral isolated mounting base.
Apollo Discovery Sounder Visual Indicator Base with Isolator (Part No. 45681-393APO)
The Apollo Discovery Sounder Visual Indicator Base with Isolator (45681-393APO) combines a sounder, visual indicator, mounting base, and short-circuit isolator into a single intelligent device. Designed for use with Apollo Discovery addressable fire alarm systems, the unit provides both audible and visual fire alarm notification while simplifying installation and system design.
The 45681-393APO can operate with a compatible detector fitted or with a cap installed for use as a stand-alone alarm device. Through the Discovery protocol, users can independently control the sounder and visual indicator, adjust volume and tone settings from the control panel, and configure individual or group-based alarm activation. Its advanced acoustic self-test and isolator status monitoring help improve maintenance efficiency and overall system reliability.
