The PAM1H handheld microphone is designed for indoor use, even in noisy areas with unidirectional noise cancelling. The microphone is used on all ECPIR access panels or intercom stations and features a PTT button. When connected to an access panel or intercom station, the microphone is fully monitored. Failure of the microphone element or an open/short circuit will be detected and reported by the system.
For correct operation and performance speaking distance approximate 2cm.
