Description

The addressable Module M221E serves for the line-

monitored integration of 2 contact detectors, such as

manual call points, sprinkler system contacts or super-

vising contacts, into the bidirectional communication

on the ADM loop with System Sensor/200 protocol.

Furthermore, it can be used to actuate external de-

vices by means of a relay output with a dry change-

over contact, via the ADM loop. Each input as well as

the output have individual status LEDs. Separate termi-

nals enable the operation of the module with or without

the integrated dual-isolator.

Accessories for mounting on a wall, on a plate or on a

DIN rail are available.

• ADM loop technology with

System Sensor/200 protocol

• Two input lines monitored for wire

breakage and short circuit

• One dry relay output
• Setting of module address via

decadic rotary switches

• Mounting in module box or by means

of mounting base
