Where we have delivered this
Frequently asked questions
Is a voice-evacuation PA required?
For many buildings the fire-safety design calls for PA with emergency announcement priority interfaced to the fire alarm. We design to the project's fire-safety requirements and test the interface at commissioning.
Can SMATV deliver HD to every apartment?
Yes — the headend and distribution are sized for the number of units and floors, and we measure the signal level at the outlets so every unit receives the same quality.
Can intercom work with our access control?
Yes — lobby intercom can release the door through the access-control system and the call can be viewed on the guardhouse CCTV.
