Among the companies in this field is SELCO A/S, which today has subsidiaries around the world, naturally also in The Peoples Republic of China.

The Alarm Monitor M4200 has provided SELCO entry to the exclusive club of DELTA marine customers, who successfully pass a marine type approval test in the first heat.

Without having to make any modifications to their product at all, SELCO has joined the ranks of the elite few; only approx. 5% of the DELTA marine customers pass this test at the first attempt.

SELCO A/S supplies a number of alarm annunciator and indicator panels well suited for closely monitoring of critical conditions in marine installations and industrial processes. Based on that fact, SELCO A/S has chosen to move the focus from the present designation; Alarm Annunciator to the new designation; Alarm Monitor.
