The 9620 is a rugged tamper resistant substation with a unique design to protect the speaker/microphone, call button and internal electronics from external abuse. The station is ideal for jail cells, sally ports, parking garages and other security applications. The speaker provides good microphone sensitivity and excellent voice quality. It provides clear, hands-free, two-way communication when called. The station provides a balanced audio line with no hum and noise, and circuitry for line supervision. The 9620 will operate on the STENTOFON 9200, 9400 and 9600 systems.
