Gas Detection System
The Controller is always used in conjunction with gas detection sensor modules and is generally
connected to alarm annunciation devices and environment control devices such as exhaust fans. The
Controller may also be connected to facility control systems or control rooms. These external connections
are not covered by this manual except as necessary to define the Controller connection or functionality.
In large facilities it is possible that gas detection systems include multiple Controllers that may not be
identical to each other. For purposes of this manual each Controller should be considered unique.
1.6
Power Requirements
The Controller requires 24 VDC at 12 Amps for a fully loaded (maximum 32 modules connected) gas
detection system. The following considerations should be noted:
•
The Controller has an integral AC/DC power supply that allows primary 120/240 VAC power
•
The Controller allows direct 24 VDC connection from a plant supply or battery backed UPS
•
The VDC source will provide power for the connected sensor modules
•
Power for ancillary connected devices such as alarm indicators must be supplied separately
