Electrical Range Smoke Alarm 10 Year Multi-Sensor FS2126-T

The FS2126-T is a multi-sensor smoke alarm manufactured by Electrical Range. It is a standalone detection device rather than a component of a boiler or heating appliance, and it is built around a 10 year service life. A multi-sensor head monitors more than one fire signature instead of relying on a single detection method.

• The alarm chirps or beeps at regular intervals, indicating the unit has reached the end of its service life.
• The test button no longer produces a full alarm sound when pressed.
• The unit has passed its 10 year replace-by date.
• Repeated false alarms that are not cleared by cleaning or repositioning the head.
• Visible contamination, insect ingress or physical damage around the sensing chamber.

• Confirm the part number on the existing alarm matches FS2126-T before ordering a replacement.
• The number 4440024 may appear on older listings or documentation for the same unit.
• Check the mounting base and wiring arrangement of the alarm being replaced so the new head suits the existing installation.
• Where the alarm forms part of a wider fire detection system, confirm the replacement matches the specification of the rest of the system.
