Lighting system with an automatic stairway lighting switch
Function of a lighting system with automatic stairway lighting
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 long-
er period of time (e.g. when cleaning the stairway). The
switch for permanent lighting is usually located on the auto
-
matic stairway lighting switch and may be difficult or impos-
sible to access.
8.1.3 Lighting system with IDEC SmartRelay
A IDEC SmartRelay system allows you to replace the auto-
matic stairway lighting 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 stairway lighting switch with IDEC SmartRelay
• Dual-function switch with IDEC SmartRelay
- Switch light on
- Switch on permanent lighting
- Switch light off
