Optical Smoke Alarm 10 Year Battery Operated - Radio frequency inter-connected
ALRFSB battery-powered optical smoke alarm with radio interconnection. Follow the supplied instructions for testing, cleaning and replacement; a long-life battery does not make an alarm maintenance-free.
Check the interlink system before ordering. The ALRFSB instructions exclude wireless alarms from other ranges or manufacturers. Confirm the exact compatible models and supplied revision; radio interconnection is not universal compatibility.
