MIKRA PUSH BUTTON PANEL
Mikra push button panels are made of zama with high resistance
against impact and damage.
Push button panels are provided with 2 call buttons and can be used
in single- or two-family systems (second button excluded with jumper)
or as secondary call station.
All push button panels can be wall mounted with screws and screw
anchors, or
fl
ush mounted for special requirements, using the suitable
box; in this case it sticks out few millimetres from the wall.
The push button panel reduced width allows its installation also on
gate pillar. To make installation easier, each module is provided with
call buttons, name holders, door unit and camera.
Push button panels are available in two different models:
