Medical Alarm two way systems
Medical alarm two-way intercom systems enable sound or
speech to be transmitted in two directions so that a conversation can take
place.
Systems may be mains or battery operated. Some have a handset which
must be used when speaking through the system, others have a 'hands-free'
facility. This allows the station to transmit messages once speech is sensed.
If no speech is sensed, the station remains on receive mode. |
