Versus Technology added a supervisory signal to its patented infrared location and communications badge, which enables hospitals and other organizations to identify the precise location of patients, staff or equipment throughout a facility at all times.
Adding a backup, supervisory signal to our infrared systems means healthcare providers are always in contact with everyone and everything that is important in the hospital.
The contractor must also inspect the transmission of the alarm, supervisory and trouble signals to the monitoring station documenting the times the signals were received and the restoration of the alarm and supervisory signals.
The current-loop and tonal systems never met this criterion because their supervisory signals repeated.
For example, alarm signals can be sent to a central station, while maintenance and supervisory signals can be sent to a receiver in the alarm installer's office.
Monitoring may include intrusion, fire, supervisory signals, emergency phone systems, and monitoring.
