Lonergan Alarms Limited was established in 1969, offering quality fire alarm installation and service on a twenty-four hour basis. Now, over thirty years later, Lonergan Alarms Limited offers the same quality along with the experience and knowledge that has kept customers satisfied for over 3 decades. Our experience and reputation are excellent in both installations and service and we still remain to offer twenty-four hour service.

Due to the ever-increasing demand of the Fire Protection Industry, Lonergan Alarms Ltd. incorporated a mechanical division in 1988 to service the fire protection industry throughout the Province of Ontario.
