Operation Testing the relay Introduction A self-test procedure can be used to check the Vigirex RMH quickly and automatically. It is possible to run this self-test without tripping the pre-alarm or the alarm. This allows the system to be checked without affecting the installation. A self-test can be run in one of the following ways: b using the keys on the front of the device b via the remote "TEST" and "RESET" inputs b remotely, via the internal bus network (see "communicating via the internal bus").
