Elmdene offers a Lifetime Warranty on its core product lines, giving you confidence in the performance and reliability of their power supplies for security and fire safety installations.
Check the fault diagnostic table in your specific user manual. Generally, a green LED indicates that the mains supply is present, while a yellow or red flashing LED signifies faults such as a blown fuse, missing battery, or mains power loss.
Most Elmdene power supply units use 12V Valve Regulated Lead Acid (VRLA) batteries. 24V applications typically require two 12V batteries wired in series. Always refer to your installation manual to confirm the specific capacity and polarity required.
The yellow fault LED may flash during initial commissioning to indicate that no standby battery has been connected yet. This is a normal function and will clear once the battery is correctly attached and begins charging.
