A closer look
Activation is smooth and easy wherever you press your finger
No more fingerprints with shot-peen st/steel
Tactile Braille is always present under the floor symbol in all Macro buttons
EN81-70:2021+A1:2022
Great contrast, better visibility
The EN81-70:2021+A1:2022 norm requires that luminance contrast between adjacent surfaces shall be evaluated in numerical light reflectance value (LRV).
When mounted on a stainless steel faceplate, the black metal ring added around the MACRO button or its black pressel provide enhanced luminance contrast to the surrounding faceplate.
Mounting
Front mounting
The MACRO button is front mounted and fits round-shaped 35,2mm diameter cut outs.
The retaining ring is part of the button body and ensures optimal solidity.
Illumination
Single lighting
Upon activation, the button halo lights up red or blue.
White illumination is also available on request for some pushbuttons.
By default, all DMG buttons are available primarily with this basic illumination pattern.
Double lighting
Simbols are always white or green illumnated.
Upon activation, the button halo lights up while the symbol/number remains illuminated in white or green (the following combinations are available white-red, white-blue or green-red).
Twin lighting
DMG introduced the Twin-lighting solution as a way to enhance button visibility in darker cabins.
Twin lighting means that both the halo and the symbol of the button are permanently illuminated in WHITE.
Upon activation, the button lights up in RED or BLUE while the white light goes off.
This advanced illumination pattern is available for some DMG pushbuttons, including the MACRO.
Which electronic?
Like all our pushbuttons, the BM Macro can be matched to different contact modules:
Screw terminals contact module
The screw terminals contact module is good for all types of modernizations. It requires a conventional wiring during installation.
It is suited for installations where no acoustic call acknowledgment is required.
Screw terminals contact module
+
call acoustic acknowledge module
If an acoustic call acknowledge is required (compliance to EN81-70), the screw terminals contact module con be supplied with a separated small module generating an acoustic signal.
It requires conventional wiring during installation. This solution is suited for both car and floor applications.
JST connector contact module
Best solution for pre-wired fixtures allowing an easy and fast “plug&play” connection.
A JST cable must be added to connect the push-buttons.
