miTEC's newly launched MEC-P20MS ‘Multi-Purpose’ Alarm Monitoring Main Panel can monitor the alarm input status of up to 20 zones in real time, and with the expansion module MEC-P20ES, the whole system can be expanded to a maximum of 100 zones, which is flexible enough to meet the security monitoring needs of different scenarios.
The system is particularly suitable for all kinds of properties and public facilities, including commercial buildings, flat houses, schools, clinics, hospitals, elderly centres, community facilities, shopping malls and industrial buildings, providing a highly integrated surveillance solution. With RS485 serial technology, it can significantly reduce cabling costs and improve signal stability and system expansion flexibility. MEC-P20MS supports various input types, including NO, NC, miTEC MECK-KIT emergency call button, flood detector, etc. Users can quickly configure them according to the actual needs of different zones through the DIP switches. Each of the 5 zones can be customised to suit the application flexibly.
Key Features
20 Monitoring Zones: Monitor up to 20 alarm zones with one panel.
Expandable System: Add up to 4 expansion panel, monitor up to 100 zones total.
Flexible Input Options: Works with NO/NC switches, MECK-KIT, and water level sensors.
Easy Zone Labeling: Change zone names using editable or handwritten labels.
Backup Power Ready: Built-in battery slot supports miTEC MPE-CH for 2 hours of emergency backup.
Quick Setup: DIP switches allow fast configuration — no calibration needed.
Compatible with Old Systems: Use the MEC-SB board to connect older devices for individual alarm output for each zone.
