0.18 kgGross weight

≤ 0.5 WPower consumption

IK07; IP65Protection Grade

-30 °C ~ +60 °COperating Temperature

5 VDCPower supply

Key features

Single mechanical buttonOne button calls one apartment and needs no menu or screen at the door.

Aluminum alloy bodyIK07 impact resistance and IP65 protection keep the module safe from rain and impact at an outdoor entrance.

Cascade powerThe module draws 5 VDC from the neighboring modules and needs no separate adapter.

Flush and surface mountingThe same body fits a flush box and a surface box alike.

Wide operating rangeIt works between -30 °C and +60 °C and at 10% to 90% relative humidity.

IP65 protection requires silicone sealant during installation.
