How many detector heads are in the H2S gas detector system?

Explanation:
Multiple detector heads are used to provide full coverage and redundancy in an H2S monitoring system. H2S is heavier than air, so gas can collect near the floor and spread in from different directions. Having four heads allows detection from all sides and at different heights, reducing blind spots and giving an earlier warning if gas begins to Accumulate. This configuration also helps ensure that if one head is obstructed or fails, the others still monitor the area, keeping people safer.
