RAMOS Optimax

Monitoring device suitable for multiple racks or server rooms with a height of 1U can monitor up to 150 sensors. Also available in GSM variant.

The Ramos Optimax main monitoring unit provides remote monitoring of the protected environment in server rooms using installed sensors measuring temperature, humidity, detecting intrusion, the presence of harmful gases or chemicals, or other potentially dangerous conditions.

This device excels in a very low profile, in the rack cabinet it occupies a height of only 1U when placed horizontally on the rails, and still can monitor up to 150 sensors. RAMOS Optimax can be expanded in 2 ways - either with basic BEX expanders (RAMOS-BEX-I8-D10) with a maximum total cable length of 10 m in one row or with standard expansion modules (RAMOS Ultra O16, I8, D64, D128, D192, RMS-ACS-U-RDU). A version of the RAMOS Optimax GSM monitoring unit with a built-in 4G modem and an external antenna is available. This version also allows you to send SMS notifications or communicate via the GSM network.

The built-in web server of the RAMOS Optimax (GSM) unit allows convenient setting, control, and operation from anywhere. In the event of an alarm, the notification is sent by e-mail or via SMS to predefined recipients (GSM version). RAMOS Optimax can also be integrated into the CONTEG Pro Server application for central management and supervision of the monitored environment. A wide range of accessories is available for the main monitoring unit, such as detectors, sensors, sirens, magnetic door contacts, expansion modules, etc.

Monitoring system RAMOS Optimax is suitable for multiple racks or server rooms.
