Alarm Collection Equipment for Remote Site Monitoring

Please fill out all form fields to process your request.


The Westell RMM-300 is an IoT remote site monitoring alarm collection device supporting up to 40 dry contact inputs via standard CAT 5 cable connections.

The Westell RMM-300 is ideal for remote site monitoring when replacing alarm functionality on legacy radio or alarming systems and migrating to modern SNMP management.

The RMM-300 can also be a peripheral remote site monitoring expansion device giving the ability to add an additional 40 monitored dry contacts to any of our other remote monitoring units.

The RMM-300 supports dual DC power and comes with reversible and rotatable ears and can be rack mounted or wall mounted on a backboard due to its shallow form factor.
