Lighting system with a current impulse relay
When a current impulse relay is used, the lighting system
behaves as follows:
•
When any switch is pressed: the lighting is switched on
•
When any switch is pressed again: the lighting is
switched off
Disadvantage: people frequently forget to switch the lights
off.
Lighting system with an automatic lighting device
When an automatic device is used, the lighting system
behaves as follows:
•
When any switch is pressed: the lighting is switched on
•
When the preset time has elapsed, the lights switch off
automatically.
Disadvantage: The lighting cannot be switched on for an
extended period of time (e.g. for cleaning purposes). The
permanent on switch is usually on the stairwell lighting
timer unit which may be difficult or impossible to access.
8.1.3 Lighting System with IDEC SmartRelay
You can use a IDEC SmartRelay module to replace the
stairwell lighting timer or the current impulse relay. And you
can 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 system with IDEC
SmartRelay
•
IDEC SmartRelay as a multifunctional switching system
with the following functions:
-
Light on: Press switch
(Light switches off after the set time elapses)
- Permanent light on: Press switch twice
- Light off: Press switch for 2 seconds
