Ex industrial telephone [Type dA24 + dA24/ZB]

(explosion-proof)

The lightweight Ex industrial dA24 telephone is designed for areas at risk of explosion. 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 deliver the dA24 with two custom keys whose functions you can assign.
The keyless version dA24/ZB is also suitable as an alarm phone.
