Synergy+ Advanced Relay Interface

Synergy+ Advanced Relay Interface – Integrated Wired & Wireless Alarm Control

The Synergy+ Advanced Relay Interface enables seamless integration between the Evacuator Synergy+ wireless system and fixed or third-party alarm systems. Operating on a secure 869MHz radio frequency, it allows alarms to communicate reliably across both wired and wireless environments. When an alarm activates, the interface closes a normally open volt-free contact. As a result, connected systems can receive a zero-volt input without requiring direct power transfer.

Two-Way System Interaction
Unlike a standard relay interface, this advanced unit supports two-way alarm control. Specifically, it accepts a volt-free input from a fixed alarm system, which then triggers the Synergy+ wireless system. Once the input is released, the Advanced Relay Interface sends a radio message to silence the connected Synergy+ devices. Consequently, users can silence both wired and wireless alarms from either system. Because of this functionality, the interface is commonly used where a temporary Synergy+ fire alarm system must connect to a fixed alarm installation. This ensures consistent alarm behaviour across the entire site.

Power Options & Wireless Reliability
The unit operates on a 4.5V battery, delivering up to three years of battery life, depending on usage. Alternatively, it can be powered by mains using the optional mains conversion kit, making it suitable for longer-term installations. Furthermore, mesh radio connectivity and a Category One radio module help maintain reliable communication across the system. An anti-tamper antenna, along with a status LED and battery low indication, also supports secure operation and routine maintenance.

Installation & Application Notes
For ease of installation, the enclosure includes two 16mm cable gland for secure cable entry. This design supports clean integration with fixed alarm wiring while maintaining system integrity.
