Lighting system with an automatic stairwell light switch
Function of a lighting system with automatic stairwell light
switch:
• Press any pushbutton: The lighting is switched on
• The lights are switched off automatically when the preset
time has expired.
Disadvantage: The lights can not be switched on for a
longer period of time (e.g. when cleaning the stairway). The
switch for permanent lighting is usually located on the
automatic stairwell light switch and may be difficult or
impossible to access.
8.1.3 Lighting system with IDEC SmartRelay
An IDEC SmartRelay system allows you to replace the
automatic stairwell light switch or the current impulse relay.
You can also implement both functions (timed off-delay and
Current impulse relay ) in a single unit. What is more, you
can incorporate extra functions without making any
alterations to the wiring. Here are some examples:
• Current impulse relay with IDEC SmartRelay
• Automatic stairwell light switch with IDEC SmartRelay
• Dual-function switch with IDEC SmartRelay
- Switch light on
- Switch on permanent lighting
- Switch light off
