PWM-101B acts as a very versatile extension of the digital VARES-3000 system. Besides a classic talk-back functionality it offers the functionality to serve as an essential security asset for precisely targeted alarms in any case of emergency. Especially in amok situations it provides a secure and prioritised communication channel between the calling point and the head office.
It is possible to send an alarm message from a classroom only to the secretariat without alerting the whole building. Each PWM-101B is equipped with an individual address code, so the secretariat is informed about the origin of the incoming call in the very moment the push-to-talk button on PWM-101B is pressed. Reactions can be initiated very quickly and targeted this way.
