Figure 2 - Polling rates and communication fail alarm transmission times
Note: The polling rates and communication fail alarm transmission times in Fig 2 may be liable to
change. For the latest information, refer to the Technical information sheet at
http://www.redcare.bt.com
Note: Where the Redcare Secure unit is connected to a PSTN line (Secure 2 & 3) then the line
should be either a dedicated line, or a line of low usage, to ensure that the necessary outgoing test
calls and alarm calls can be made when required.
