Locksmiths Cardiff Install Voice door entry systems to residential blocks of flats, Small offices, Schools, Industrial units and retail premises in the Cardiff area. Occasionally we are also asked to install voice entry systems in the homes of disabled or elderly people with mobility problems.
Typically an electronic door entry system will consist of a dual buzzer and speaker unit mounted on a wall next to a main entrance door. A caller will press the buzzer which then calls a telephone unit inside the property. People inside can then pick up the telephone handset and speak to the caller on the outside.
If they decide to allow the caller to enter the property, they push a release button on the telephone handset and this will then activate an electronic door release and allow the caller access to the property.
The door release unit could be in the form of an electronic receiver for use with Yale or mortise latch type locks. On Commercial property it would typically be a door magnet mounted towards the top of the door.
These systems are normally powered by a 12v AC or DC transformer which is connected to the mains.
Voice door entry systems provide an excellent means of access control in small businesses and residential houses.
Voice entry systems are also available combined with a code entry system. This would allow employees for instance to enter a code and gain entrance. But visitors would need to press the buzzer and speak to a receptionist before being allowed entrance.
