The base station receives and processes signals from Hanwell radio and wired sensors. These sensors communicate at regular short intervals with this base station, (the cr-1) which logs and stores the data pending transfer to a PC for analysis and archival storage. The cr-1 also provides an interface for the MS1000 control system.

All data from the sensors, whether radio telemetry or hard wired in any combination, is ultimately collected, processed and stored by the cr-1. This can be located conveniently and is designed for continuous monitoring of the entire System.

A 16 x 1 character (desktop version) or 20 x 4 (wall mounted) LCD displays the system status. It also signals alarm conditions via the front panel LED'S (should any sensor measure above or below individual pre-set levels). Although the cr-1 has an extensive memory capacity it is intended that the data is transferred to a PC for detailed interpretation and permanent storage. This can be done automatically or manually at any time.

The base station is available in the following configurations:
• Desktop (pictured above right)
• Wall mounted with panel printer option
• Rack or panel mounted
• Simplified version for direct connection to a PC
