Interlinked protection with no cables at all: battery powered optical alarm with built in RadioLINK+ radio module.

Every Ei650iRF on a system sounds when any one of them detects smoke, with nothing more than a screwdriver needed to install. It is the fastest way to bring a rented flat or house up to an interlinked standard, and it works alongside the Ei603RF heat alarm, the Ei208WRF CO alarm and the Ei450 controller.
Delivery £5.95, free on orders over £75.00. Tracked courier, 2 to 4 working days. UK addresses only. 14 day returns on unused items.
