The SensAlertController, housed in a NEMA 4X enclosure, providesseparate single pole double throw (SPDT) relays foreach alarm condition, plus one common relay for afault condition. It also serves as an interface when anevent needs to be relayed to a peripheral device, suchas a building fire alarm system.

9 The SensAlert Control-ler displays can display gas levels in either ppm, %vol,or %LEL, depending on the installed power supply for the CONTROLLER has been designedto operate at 90-265 VAC, with the capability of add-ing a 24 Vdc backup power of the features of SensAlert four CHANNEL Con-troller include: Auto-recognition of sensors Lo, Hi, HiHi, & Fault alarms User-selectable alarm levels Three relay contacts per sensor Lockout/tagout designed case RS-485 serial output 4-20 mA / 1-5 volt output Password protectionPRELIMINARYS ensidyne Document No. 7013227M (Rev H)9 SENSALERT four CHANNEL HousingThe NEMA 4X enclosure is made of high-grade, fiber-glass reinforced polyester resin matting. The enclosureprovides a weather-resistant and water-resistant barrierbetween the internal electronics and the ambient envi-ronment. The CONTROLLER cover is secured to the hous-ing with 2 quick release latches. Each latch has asmall circular knockout that allows the case to belocked or tagged to prevent unauthorized Reset switch is located on the bottom of the con-troller housing (refer to Figure ).

10 The switch can beused to (1) unlatch a latched alarm, (2) silence a localLo Alarm, or (3) enter Calibration Mode (whenpressed for 5 seconds).The Alarm Buzzer is located on the bottom of thecontroller housing, next to the cable glands. Thealarm buzzer is used for the Local PCBThe Display PCB contains the large, 3-digit LED dis-plays, the LCD displays, and the operator buttons thatcontrol the menu system. The Display PCB connectsto the Bottom PCB via a 20-pin flex cable. The com-ponents on the Display PCB are described as follows. Liquid Crystal DisplayThe Liquid Crystal Display (LCD) is a 16 character, 2-line display located behind the front cover of the con-troller enclosure (see Figure ). During normal op-eration, the display shows the gas name and gas con-centration (in ppm, %LEL, or %vol) for the sensor in-stalled at the transmitter. The display is also used forviewing and changing various features of thecontroller ( , alarm settings, passwords, etc.).During alarm and fault conditions, the display showsstatus messages on Line 2 describing the nature of thecondition ( , Lo Alarm, Missing Sensor, etc).
