Apollo Series 65 Diode Base (45681-201APO)

The Apollo Series 65 Diode Base (45681-201APO) is designed for use in conventional fire alarm systems where manual call points and detector bases share the same circuit. The base incorporates a Schottky diode on the L1 IN and L1 OUT terminals, enabling compatibility with specific control equipment while helping maintain reliable system operation.

The 45681-201APO supports continued circuit operation if a detector is removed without authorisation, helping to maintain protection across the remainder of the system. This feature makes the base particularly suitable for installations where system integrity and fault tolerance are important.

As part of the Apollo Series 65 range, the base combines simple installation with dependable performance. Features such as a one-way detector fit, detector locking mechanism, and easy wiring connections help reduce installation time and ensure correct detector positioning.
