DESCRIPTION

Staircase switch enables delayed switching off of lighting on stairs, corridors, entrances, common areas or for delayed running of fans in the toilet or bathroom.
The programmable staircase switch offers similar application possibilities as the CRM-4, while it is possible to extend the delay for functions a, b repeatedly by briefly pressing the control button (buttons). Each short press multiplies the time set by the potentiometer, i.e. setting the potentiometer to 2 minutes with three presses extends the delay up to 6 minutes. The maximum value of such an extended delay will always be 30 minutes, regardless of the number of presses.
Long press (>2 s) can switch off the output prematurely and end the ongoing delay.
Control input with the possibility of loading up to 100 mA load (glow lamp, LED in the button, etc.).
Function (selectable by potentiometer on the front panel)
- a – STAIRCASE SWITCH, programmable with signalization
- b – STAIRCASE SWITCH, programmable without signalization
- c – MEMORY LATCH (press to switch on, press to switch off
- d – MEMORY LATCH with delay
- ON (permanently closed) - e.g. during cleaning, moving
- OFF (permanently open) - e.g. when replacing luminaires.
ZERO CROSS feature: closes the output contact when the voltage crosses zero.
Adjustable time delay (t) 0.5 – 10 m.
Handles surge currents up to 80 A.
3-wire or 4-wire connection (input S can be controlled by potential A1 or A2).
