Ex industrial telephone
[Type dA24 + dA24/ZB]
The lightweight Ex industrial dA24 telephone is designed for explosion prone areas. It can be used as a PABX device and end device as well as for DTMF or pulse dialling. In the event of loud environmental noise, you have the option of turning on an integrated handset amplifier. A continuously adjustable fixture protects the telephone handset against shocks. The robust 16-part keypad can also be ordered with lighted keys. Upon request, we can also supply the dA24 with two self configurable keys.
The keyless version dA24/ZB is also suitable as an alarm phone.
