CRM-46 | Intelligent staircase switch with the possibility of output signalling before switching off

  • Combines the functions of the original CRM-42 / CRM-42F relays and adds new ones.
  • 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 intelligent 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 (s). 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. On the other hand, a long press (> 2 s) can switch off the output prematurely and end the ongoing delay.
  • Possibility to select a function with signalling (function a) or without signalling (function b) of the output by flashing 40s and 30s before the delay expires.
  • Output contact handles surge currents up to 80A
  • Control input with the possibility of loading up to 100mA load (glim 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
  • Adjustable time range 0.5… 10 minutes.
  • 3-wire or 4-wire connection (input S can be controlled by potential A1 or A2)
