Legrand’s ionisation smoke alarms ‘feel’ the smoke. They detect invisible particles of combustion, eg, from cooking toast. They activate more quickly for fast, flaming fires with little visible smoke.
The company says that the alarms, suitable for general use, are good for fast flaming fires with little visible smoke. They are less prone to false alarms caused by dust and steam.
Other features include: interconnectable - up to 20 units; surface mounting for easy fit-off; power and alarm indicator; easy access for wiring; hush/test button; 9 V battery back-up included; duct cover to protect the device during installation; smoke detector interface available separately to interconnect with other appliances, circuits and systems, eg, lighting and exhaust fans.
