The weatherproof A24 is suited for dusty and moist environments. It is designed for DTMF and pulse dialling as well as a PABX device and end device. Its keypad consists of 16 durable buttons that can also optionally ordered to light up. A continuously adjustable fixture protects the telephone handset against shocks. An integrated volume amplifier can be added on. We are also happy to offer the A24 with two custom buttons that can be assigned other functions as desired.
