MUTE DURATION “RINGBACK” (Snd)
This feature can be considered as a “nudge” alarm. If a user mutes the audible alarm,
but an alarm condition persists, the audible alarm will ring back after 120 minutes later
(factory setting). This is to prevent a serious alarm condition to be ignored.
CALIBRATION / OFFSET (OFF)
Before making an OFFSET change, please note that this procedure should only be
carried out by a certified technician with a NIST traceable calibrated thermometer.
This feature allows a user to change the temperature reading with +/- 10 degree
differences.
For example, if a technician’s NIST traceable calibrated thermometer is reading 5C,
while D-100 reads 3C, make a +2C change in OFF setting.
REMOTE ALARM DELAY (rD)
It is a time delay after the visual and audible alarm being activated. It gives users some
time to correct an error, before sending the alarm to the remote monitor system.
For example, rD is set to be 20 (minutes). A user forgets to close the refrigerator’s
door, and the temperature warms up to 10C. The High Temp (HA) visual and audible
alarm will be activated. If the temperature continues to stay above High Temp, 20
minutes later the remote alarm will be activated.
Please note, Remote Alarm will be immediately activated during a power failure event.
It would be deactivated when the power resumes and the temperature returns to
normal.
REMOTE ALARM SYSTEM (SPST RELAY)
It is recommended to contact your facility manager, or a local technician to assist you
in connecting the remote alarm system.
D-100’s remote alarm system is wired to be gray and white leads. It is located at either
1) underneath of top sign canopy, or 2) behind the unit, next to the compressor.
During non-alarm state, the remote alarm system is at CLOSED position (NC). During
an alarm state, the system is at OPEN position.
Rating: 3 amps.
