The parts of a system
A control panel connects detectors, manual pull stations, horns, strobes and sometimes door releases and elevator recall. Devices are placed according to code, based on room size and use.
Monitoring services pass alarms to a central station.
The details, such as device type and spacing, come from the code and the system design. Our in-house engineering group prepares the drawings for review.
Why renovations change it
Moving or adding walls can leave detectors blocked or alarm signals unheard. New ceilings may change device mounting. The system must be altered and re-verified.
Our electrical and low voltage teams plan device changes with the layout so the system stays compliant.
Dust, paint and drywall work can trigger false alarms, so detectors are protected or disabled during construction, with a fire watch in place.
Verification
After work, the system is tested and verified by qualified people, and a report is provided. Authorities may require this before occupancy.
Do not cover devices during construction without protection, as dust can cause false alarms.
Plan the test date early, because authorities and verifiers need notice.
Coordination with other systems
Alarm systems connect to sprinklers, door hardware, ventilation shutdown and emergency lighting. Planning these links early prevents conflicts.
Because we install electrical, low voltage, and doors and hardware ourselves, all of these connections are handled by one team.
Keep it working
Regular inspection and testing are required by code, and records must be kept. Our building maintenance service can schedule these checks, so deficiencies are found and fixed promptly.
Keep the panel accessible and make sure staff know who to call if it shows a trouble signal.
Questions we hear
Can we alter the system ourselves?
No. Qualified people must make changes and verify the system, and permits may apply.
