ALM RLY connector 6-pin RJ-12 connector with dry contacts for relaying alarms from the
MX-2100 to activate external equipment (such as lamps, buzzers, fans).
The Alarm Relay connector can also be used to relay external
equipment information to the MX-2100 (such as external sensor
information, or fan failure).
Connector rating: Max current is 500 mA, Max voltage is 50V
For pinout refer to
Appendix A.
Connections to the Supervisory Port – KCL.2 Module
Find the supervision cable intended for connection to the enclosure, and connect
it to the SP connector on the KCL.2 module.
If the optional dial-out port is to be used, connect the corresponding cable to the
MNG connector on the KCL.2 module.
Connections to the Alarm Relay Connector – KCL.2 Module
Connect the external equipment to the RJ-12 Alarm Relay connector according to
the pin assignment described in Appendix A.
The connector functions as a dry contact relay. Under normal conditions, the
Normally Closed (NC) pin is shorted with the Common contact. When a MX-2100
alarm occurs, the Common contact will instead be shorted to the Normally Open
(NO) pin and the device connected to the connector will be activated (similarly to
how the Alarm LED on the MX-2100 front panel is activated).
Connections to KML, Options, I/O Modules, and Ringers
Refer to the corresponding module/ringer Installation and Operation Manual.
