Its quick-swap Easi-fit base and clear LED indicators make installation and monitoring effortless. Certified to top UK and European standards, it integrates easily with other alarms via wired or optional wireless connections, delivering a modern, dependable fire safety solution. ## Description Normally installed in locations where there is a high risk of false alarm caused by routine use, e.g. Kitchen, Garage, Loft and Boiler Rooms. These locations are often overlooked when in fact they are the riskiest places for fires to start. Heat Alarms should always be used in conjunction with Smoke Alarms, they will not provide adequate protection on their own. As with the rest of the 140e Series alarms the Ei144e Heat alarm can be interconnected with other alarms and accessories through hard wire connection or, for less mess and disruption, by RadioLINK wireless interconnection. Wireless devices are sold separately. Review: Easy to swap-out - Slides straight onto the old models base making the replacement take seconds. Very good! Review: Compatible with previous discontinued model - so just slide onto old base to use. - Arrived within 2 days and exactly model ordered to replace unit that had been in place nearly 10 years. This is a new model designed to fit onto the existing base unit and work in tandem with other wired smoke alarms in the house. Very happy that did not require fitting new base and rewiring the base plate - just a 2 minute job to swap the sensor units - I also fitted a new smoke alarm on the stairs from the same manufacturer as that was also reaching its certified date. ## Features - Heat sensor – responds to heat build-up from large flaming fires.
