The Telephone Unit type 229A1 or 229A2, is a telephone intended for the transmission of electric signals to a Private Automatic Branch eXchange

The telephone is composed of:

 - a casing protected by increased safety which contains:

  • a printed circuits board protected by intrinsic safety allowing connection from the microphone, the handset and the keyboard with keys,
  • two printed circuits board embedded in a resin and protected by encapsulation.One of these boards comprises, on its higher face, two terminals "e" (located BR1 and BR2) for the connection of the external electric circuits.

 - a telephone headset protected by intrinsic safety,  
 - a second receiver, in option, including a standard ear-phone also protected by intrinsic safety
 - a headset, in option, according to maximum coils and capacities allowed by the intrinsic safety circuit.

 

The casing, made out in polycarbonate stainless steel filled compound, painting in option, is composed of a body closed by a lid maintained by 4 screws. The Telephone Unit type 229A1 is provided with an backplate behind the keyboard sealed by silicone while the keyboard of the type 229A2 is sealed with neoprene directly to the coverplate without the backplate.
The enclosures get the degrees of protection IP64 in accordance with IEC 60529.
