Apollo 45681-508APO Series 65 Base - Relay (12V)

The Apollo 45681-508APO is a 12V relay base for Apollo Series 65 conventional smoke and heat detectors. It is often used to add smoke or heat detection to intruder alarm systems. A jumper on the PCB sets the base to latching for fire systems or non-latching for security systems, and the relay gives volt-free changeover contacts when the detector goes into alarm.

Key features

• 12V relay base for Series 65 conventional detectors
• Jumper selectable latching (fire) or non-latching (security) operation
• In non-latching mode the base resets itself about 15 seconds after an alarm clears
• Changeover relay contacts (NC, C, NO)
• Detector locking mechanism
• One-way fit
• Easy to wire, with an earth connector
