Low voltage and security

Intercoms

Intercoms let staff see and speak to visitors before opening the door. HSM's own low voltage team installs door stations and ties them into access control.

Intercoms

Why intercoms matter

Many businesses keep entrances locked for safety, particularly after hours, in clinics and in multi-tenant buildings. An intercom lets staff confirm who is at the door, speak with them and release the lock from their desk or phone.

It supports accessibility too. People who cannot easily reach a door can call for help.

Types of systems

  • Audio-only door stations
  • Video door stations with camera and display
  • Network-based systems that ring desk phones or mobile devices
  • Directory systems for multi-tenant buildings
  • Staff-to-staff communication and paging
  • Emergency call stations in parking areas and stairwells

Integration

An intercom is most useful when linked to other systems. The door station can unlock the entry through the access control system, show a camera view and log the event. Our low voltage team sets these links up as one system and not as separate devices.

Fire alarm integration is a safety requirement for locks. The door must release in an alarm. Our electricians and low voltage staff coordinate this with the fire alarm work.

Installation and conditions

Door stations at entries face weather. Alberta cold affects batteries and screens, and snow can block cameras and speakers. Units need cold-rated equipment, a protective canopy where possible and a heater in some designs.

Location matters. Mount stations at a height people can reach, including those in wheelchairs, and avoid glare on the camera. Lighting at the entrance helps video quality.

Cabling, power and backing should go in during rough-in. Our carpenters and electricians can prepare the door frame, and our door hardware crew coordinates strikes and locks.

Plan for how calls are answered. Reception, security staff or a mobile app may be involved, and the system should have a fallback if the first person does not answer. We train your team and document the setup. Our maintenance service keeps systems working as the building changes.
