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
