Product details
The Apollo 58002-300APO Discovery Base Sounder is an addressable, loop-powered sounder base designed for integration into Apollo Discovery fire alarm systems. Compatible with the XPERT 7 and XPERT 8 bases, it offers a straightforward installation process and extensive flexibility in tone and volume configuration, making it a reliable choice for both new installations and system upgrades.
Featuring 15 selectable tone pairs and 7 volume levels, the Discovery Base Sounder can be configured to meet the audible requirements of most building types, from commercial offices to industrial environments. Its built-in controllable isolator adds resilience to the loop, isolating a fault without disrupting the rest of the circuit. Setup and testing can be carried out either via the control panel or directly at the device location, reducing commissioning time and simplifying ongoing maintenance.
Please note: an XPERT base is required to install this device and is sold separately.
