ZYCOO BM11, Call Button, Microphone, for SC15, SW15

Pressing the ZYCOO BM11 call button dials a preset destination and opens two-way talkback through the connected SC15 or SW15 speaker, adding intercom calling to one-way paging; the LED flashes on an incoming call, and pressing again answers it. ZYCOO's current documentation markets the same function as the EA-B11 Call Button, which this Internal Reference likely matches. It suits a gate, lift lobby or reception desk. Installers in Dubai can request a quotation by part number.
