Confined Space Communications

Safelink allows two Impact Pro portable multigas monitors to be connected together such that the gas readings and instrument status from one are repeated on the other. This allows a co-worker in a confined space to be monitored remotely as well
as providing a simple means to pass messages back and forth.

Safelink is designed to simplify compliance with confined space entry regulations and working practices. Generally, two people are required to carry out confined space entry procedures correctly. One, the ‘Attendant’, must continuously monitor the status of the other ‘Entrant’ and initiate rescue procedures if necessary. When the Safelink cable is attached to the two
Impact Pro instruments the link is automatically recognized.
One instrument is configured as the ‘Attendant’ and the other is automatically designated as the ‘Entrant’; neither instrument can now be turned off.

The ‘Attendant’ is prompted at regular timed intervals to send a message to the ‘Entrant’ who has to reply by pressing any button on the instrument. If no reply is received both instruments raise alarms. Other pre-defined messages may
be configured using the optional PC software allowing a flexible
method of communication to be established.
