Monitors for high or low temperature conditions. The system utilizes an accurate solid state temperature sensor and microprocessor based digital circuitry to sense and report abnormal temperature conditions. Standard sensing range is 40°F (4°C) to 199°F (93°C) switchable. The alarm panel can be mounted remotely and provides both audible and visual indication of alarm condition. With the addition of a solenoid, the system can perform an emergency shutdown function. A unique latching circuit is used so that the alarm holds despite a return to normal condition. This feature indicates that a dangerous condition did exist. After return to normal, that reset button must be depressed to cancel the alarm. The system will only return to normal if condition has been corrected. The alarm module can be panel-mounted or recessed in a wall, the same as a standard 4 x 4 electrical wall box. The Series 460 AquaSentry2 Alarm System meets the standards for the Joint Commission on Accreditation of Hospitals (JHACO) and the Accreditation Council for Services for Mentally Retarded and Other Developmentally Disabled Persons(ACMRDD).
