Why choose it

This detector eliminates the hassle of battery replacements, providing constant protection through a wired connection. Its photoelectric sensor is less prone to false alarms from cooking fumes compared to ionization types, making it ideal for residential use. The relay output adds versatility, allowing connection to external alarms or control systems. With a wide operating temperature range and high humidity tolerance, it performs reliably in various indoor environments.

Ideal use cases

• Residential homes, apartments, and hallways
• Small offices and commercial spaces
• Integration with security or fire alarm systems via relay
• Areas where battery maintenance is impractical

Good to know

The detector is designed for ceiling mounting and includes a test button for regular function checks. Its automatic reset feature clears the alarm once smoke dissipates, reducing manual intervention. For larger buildings, multiple units can be interconnected to sound all alarms simultaneously, enhancing safety. The ABS housing is durable and blends with most ceilings.
