Key Features 

• Dual Sounder Outputs: Two independent sounder circuits, each fully monitored for open and short circuit faults.
• Single Loop Address: Occupies one address on the fire alarm loop.
• Fault Monitoring: Provides full monitoring of both sounder circuits.
• Auxiliary Input: Monitored input can be used for local power supply fault monitoring or as a general-purpose input.
• Integral Short-Circuit Isolator (SCI): Ensures loop integrity in case of wiring faults.
• Fuse Protection: Each alarm circuit fused at 1 amp.
• Synchronization: Outputs are synchronised and can be driven continuously or intermittently.
• Power Requirements: Requires 24 V DC auxiliary power.
• Mounting Options: Available in standard module form or DIN rail mountable version.
• Environmental Protection: When used with the CHQ-BACKBOX, the IP rating increases to IP65, making it suitable for harsher environments.
• Approvals: LPCB approved, compliant with EN standards.
