Setting Alarm Delays
To configure alarm delays and other system
timings, press the MUTE/MENU button twice
while the system is showing the probe readings,
or once if you are already in the
Edit
Limits
menu.
Use the STEP button to go to the next
parameter, or the TEST/RESET button to go to
the previous parameter.
To change the currently displayed parameter, use the UP and DOWN arrow buttons. All delays
are given in minutes.
While in the
Edit Times
menu, the STEP button will advance through an
AlarmDelay
for each enabled probe, then a
RelayDelay
and finally a
Mute
time.
Return to the probe readings by pressing the MUTE/MENU button once.
Door Switch Alarm (Optional)
A single dry-contact switch input is available as an option on certain Multi-Probe Alarm
Systems. Additionally, some units have the capability to have their probe inputs configured as
switch inputs. Either of these options must be specified during ordering, it is not available on all
units, and is not user configurable.
Typically the door switch input is used in conjunction with a magnetic reed switch mounted to a
refrigerator or freezer door. If the door is left open for longer than the
Edit Times
parameter
DoorAlrmDly
, an alarm condition is generated. The switch input can be used
with either normally open (NO) or normally closed (NC) contacts.
The user should set the Setup parameter
DoorAlarm
to activate this feature. To view the
current status of the Door Input, tap the STEP button.
For units that have multiple probe inputs configured as dry-contact switch inputs, the normal
probe configuration parameters are used to configure the alarms and delays.
