The RM 41 registering unit enables the recording of all alarms triggered using a non-volatile memory. It is connected to the paging installation in a analogous way as the other devices using INSEL data-bus. Additionally, the RM 41 unit can be connected to existing LAN network thus enabling the institution manager to control and analysis of all incidents on remote computer. This is completed with dedicated software included in the RM 41 package. Each registering unit is recording incidents from only one ward but monitoring of signals is possible on every unit available and connected to the LAN network. If no LAN network is available all data can be recorded on a simple pen-drive and transferred to the computer for control and analysis.
