The Apollo 45681-201APO Series 65 Diode Base is a specialist mounting base designed for conventional fire detection systems where manual call points and detector bases share the same circuit. Featuring an integrated diode, this base ensures proper discrimination between detector activation and call point operation on two-wire conventional systems. Part of Apollo's renowned Series 65 range, it incorporates a detector locking mechanism to prevent unauthorized removal while maintaining system integrity during maintenance. The base includes an earth connector for reliable system earthing and features a one-way fit design that ensures correct detector alignment. Easy to wire with generous termination points, it provides a secure and reliable foundation for Apollo Series 65 detectors in commercial and industrial fire alarm installations. Backed by an exceptional 10-year manufacturer warranty.

Frequently Asked Questions (FAQs)

1. Why does this base require a diode for certain conventional systems?
The diode provides electrical discrimination between detectors and call points on two-wire conventional circuits, ensuring the panel can distinguish whether a detector or call point has activated for proper system response.

2. Can this base be used on standard conventional systems without call points?
Yes, it can be used on any conventional system with Apollo Series 65 detectors. The diode does not affect normal operation but provides additional functionality when call points share the same circuit.

3. How does the detector locking mechanism work?
The base incorporates a simple but effective locking feature that secures the detector in place, requiring a small tool to release for removal. This prevents unauthorized tampering while allowing easy access for maintenance.

4. What is the advantage of the one-way fit design?
The one-way fit ensures detectors can only be inserted in the correct orientation, guaranteeing proper alignment of electrical contacts and preventing installation errors that could compromise system reliability.

5. Is this base compatible with other manufacturer's detectors?
No, the 45681-201APO is specifically designed for Apollo Series 65 detectors. Using non-compatible detectors would compromise mechanical fit, electrical connection, and system integrity.
