Business and warehouse intrusion alarms
An intrusion alarm protects your building after hours: door and window contacts, motion sensors and glass-break detectors report to a panel, which can trigger a local siren and send a signal to a monitoring station. Offices, warehouses and industrial sites each need a different sensor layout: a warehouse yard door and a loading dock are not protected the same way as an office entrance.
Detection and sensors
Beyond standard motion and door or window contacts, we can add glass-break detectors and environmental sensors (temperature, water and power loss, useful for server rooms and mechanical areas) where they fit the site.
Fire alarm systems
We also install and monitor fire alarm systems, kept on a separate zone from intrusion detection: fire signals have their own code requirements and have to reach the fire department and your monitoring station correctly, so the two systems are never treated as interchangeable.
Alarm panels and remote management
Modern panels use a cellular or IP communicator so monitoring keeps working if the phone line or internet is down, and most systems let you arm, disarm and check status remotely from an app, with alerts when something happens. See wired versus wireless alarm systems for how we choose sensors for a site.
Professional monitoring
Our alarm monitoring is provided through API Alarm, a ULC-certified monitoring station, with our phone line answered 24/7. Monitoring means a trained operator responds to a signal and follows your call list or dispatches, even when nobody is watching a phone. See alarm cost and monitoring in Ontario for what affects price and whether monitoring is worth it.
Works with your cameras and access control
An alarm event can be checked against the matching camera footage, and an access-controlled door can be tied into the same panel. See video surveillance and access control for how the systems work together.
Brands and support
We install and support DSC, Honeywell, Paradox and IQ by Johnson Controls alarm panels. After installation we test the system with you, show you how to use it day to day, and stay available for service, monitoring changes and upgrades.
