❑
Installation options
The LPI series has a number of features to ensure easy installation:
• Front or rear mounting
• With or without sealing
• 2 separate circuits for NO/NC 5A version
• Terminal block connector for 0,1A NO version
• 3 different LED voltages: 6V, 12V, 24V
• Integrated LED resistor
❑
Aesthetic options
• Ring or dot illumination
• Wide range of LED colours
• Wide range of bezel colours
• Many different actuator types and colours
❑
Applications
Because of its large actuator, this product is suited to all indoor applications
where the pushbutton needs to be located quickly (access control, call
information, museums, exhibitions). This product is also ideal for applications
where the end-user uses gloves.
This product meets the requirements of EN81-70 and is ideal for use in all types
of indoor lifts.
