The agreement is with Falkirk-based Link Group, which manages more than 10,000 properties north of the border.
Shares jumped 10.5% to 19p in early deals on Friday.
This is the third contract win with a Scottish housing association in the past month, as AIM-quoted FireAngel benefits from new regulations brought in by the Scottish government in February.
Every home must now have a smoke alarm fitted in the living room and in circulation spaces such as hallways, landings, while heat alarms must be installed in kitchens. All alarms need to be interlinked as well so they can be heard throughout the property.
Homes are also required to have a carbon monoxide alarm fitted wherever there are fixed combustion appliances.
“Today's announcement with Link Group is the latest in a series of agreements with housing associations following the implementation of the Housing Scotland Act,” said chief executive Neil Smith.
“We are pleased to see such traction, which further validates how well-placed FireAngel is to respond to demand for compliant, interlinked products following the introduction of the regulation.”
