System Maintenance & Monitoring As Standard

Our maintenance contracts ensure your system remains intact and operational 365 days a year. Our yearly remote and on-site inspections pick up on any potential issues before they arise and in rare cases where problems do occur, we’re the first to know and quick to fix.   They also come with a guaranteed 4 hour response time 365 days a year, technical support over the phone, cheaper rates on parts and materials and can often lead to a reduction in your home insurance premium.

Optional Eyes & Ears on Your Property

Did you know we offer an intruder & fire monitoring service? Time is of the essence to limit the damage caused by both burglary and fire and our monitored systems guarantee an immediate response.

Our monitoring services triggered by motion, fire, heat & smoke detectors send alerts to our response team (and the police/fire services) as well as your phone so that potentially catastrophic situations and accompanying emotional distress are mitigated as much as possible – even when you’re out or away.

Don’t forget: All of our products are insurance approved to potentially save you money on your home insurance!
