It is designed to meet BS5588 Part 12, it provides clear voice communication between any two of thirty-two stations.

• Wiring Is 'Free Topology'. Using Echelon™ LonWorks™ protocol the layout's flexible, with only 4 wires needed for each unit.
• Clear & Simple. Essential in an emergency, BigVoice™ LCD screen shows Caller ID and location on each station.
• Speech is collected via a sensitive microphone and digitised for transmission. Even a soft voice 2 metres away is clearly heard so BigVoice™ can be installed in the car ceiling.
• “Hands Free” conversation controlled by “Press to Call” button on the Master.
• Multiple calls made are displayed in a queue and prioritised.
• Menu Functions Protected. The user has a “Security Pass Code” to action system functions.

LittleVoice™ meets the requirements of a Fire Fighting Lift but is not restricted to this use and is found as a simple lift intercom for point-to-point, such as the lift car to a Warden's Office, the Building's Reception or a Security Desk.
