Staircase lighting timer ASM-03 is 

used for staircase and hall lightning 

controlling. After a signal it switches on 

the lightning for a set time and then au-

tomatically switches off. Working can be 

smoothly regulated from 3 to 30 min by 

potentionometer placed on front panel of 

the automat. 

ASM-03 is equipped with 

con-blockade function and ON/OFF 

function.
