Description

The addressable Control Module SMÜ-55000-852 ser-

ves for the line-monitored actuation of external devices, 

such as fi re controls and acoustical or optical signal-

ling devices, via the bidirectional communication on the 

ADM loop with Apollo/Discovery protocol. The external 

devices are actuated by means of a monitored output.

An external supply voltage is required for powering the 

external devices.

The address is easily selected by means of a built-in DIL 

switch. The module has an integrated dual-isolator and 

is fi tted into a plastic case. Status LEDs indicate the 

condition of the output and the dual-isolator. 

•   ADM loop technology with

Apollo/Discovery protocol

•   One line-monitored output
•   Output line monitored for wire 

breakage and short circuit

•   Setting of module address by means 

of address switch

•  Integrated dual-isolator
