Specifications are for models with one GM tube. Models with 4 GM tubes (RadAl™-1/4 and RadAl™-1-WP/4 have twice the sensitivity and speed.
Connections to relay and communication ports are by  terminals accessible through wall passages.
Computer programs can be provided to demonstrate and test communications.
A detailed report: "sensitivity tests using Am241 and Cs137 sources " is available documenting alarm response thresholds.
No toxic nor radioactive materials are used in these instruments!
