Are you using fire-rated batteries?
 
For all fire and security installations, regulatory standards require fire-retardant batteries to help control fire spread in PS2 circuits. Using flame-retardant batteries, such as those certified UL 94 V2 or higher, isn’t just a recommendation—it’s essential for safety and compliance.
 
The PS-1270VdS FR is part of our VdS approved PS range of sealed lead acid batteries (often referred to as VRLA) which have been specifically designed for general purpose and standby applications. The 12V 40.00Ah battery offers excellent performance in a wide range of applications including security and fire protection systems, medical devices, emergency lighting and UPS systems.
 
All Power Sonic batteries are subject to stringent quality controls through every step of the manufacturing process ensuring both consistency and reliability.
