This module monitors the switching status of buttons for
up to two separate stairwell illuminations and transmitts
the particular switching status via a RS-485-busline to the
controller of the system AT-S
+
.
In mains operation the circuits of stairlight and emergency
light will be operated according to the settings for the
controller CU-S
+
! In addition to this, a supply of the
switcher glow lamps of the connected buttons in mains
operations occurs. In emergency operation all luminaires
switch automaticly in mains mode.

Application
•
Assembly in the subdistribution board of the monitored
circuits due to the low laying effort for the illumination
circuits (compare «Mounting and Connection of external
bus modules»).
•
Assembly in the control cabinet AT S+ C (AT S+ S)
due to reasons for simplification of the maintenance
(compare «Mounting and Connection of external bus
modules»).
