Alarm Delay

All

This sets the time period that an alarm condition can exist before the

 

Time

 

 

alarm is triggered. This is useful for helping to prevent false alarms from

 

 

 

 

occurring in situations where normal activities cause conditions to tem-

 

 

 

 

porarily exceed alarm thresholds. For example, the temperature in a

 

 

 

 

freezer may temporarily rise above the High alarm limit while frozen food

 

 

 

 

is being restocked and the freezer door is open, but the delay prevents

 

 

 

 

the alarm from going off unless the temperature fails to cool below the

 

 

 

 

alarm threshold within the alarm delay period.

 

 

 

 

 

Relay Operation

This section describes the operation of the base unit's relays. The relays must be programmed correctly so that their outputs provide the desired signaling to the alarm panel.
