Jamesway's Back-up Alarm System offers Hatchery personnel a reliable method of monitoring critical operating temperatures.
The High Temperature Back-up Alarm System provides a secondary method of monitoring an above normal operating temperature in an incubator or hatcher. The unit is micro-controller based, and is capable of monitoring up to sixteen circuits. Each circuit may consist of more than one machine. Mercury thermostats are used as the temperature sensing device. The Back-up Alarm System can also be used with any manufacturer's brand of hatchery equipment.
Each of the sixteen circuits has one green and one red LED, which indicate the state of the circuit. If any circuit is in an alarm condition, then the alarm light will flash and the alarm relay will activate.
An alarm cancel (reset) switch provides the operator with a means of cancelling the alarm. The test switch verifies proper functioning of the LEDs and the alarm relay; it does not test circuit operation.
The Back-up Alarm will enter into an alarm mode if a high temperature condition occurs or if the thermostat is removed from any one of the active circuits. The LEDs will continue to flash, indicating an alarm condition has occurred on the activated circuit. They will remain flashing until acknowledged by hatchery personnel.
System Features:
Each one of the connected circuits must be activated by pressing the appropriate switch, located on the front door panel of the control box.
When an alarm condition occurs, the circuit LEDs will show the status of the line, the general alarm light will flash, and the alarm relay will be activated. The condition remains active until it is acknowledged by pressing the reset switch (alarm cancel). The alarm condition must be corrected within fifteen minutes or the alarm will be reactivated.
There are several conditions that will affect the normal method of alarming. If another circuit alarms after an alarm has been cancelled, the audible alarm will be reactivated, cancelling the previous alarm acknowledgement. If an alarm condition is still present when an alarm is acknowledged, then for the next fifteen minutes, that circuit's alarm condition may be removed and reactivated without the audible alarm.
However, if the alarm condition has been removed before the alarm is acknowledged, and the alarm occurs on that circuit, the audible alarm reactivates.
