CONFIGURATION MODE
PROBE CALIBRATION (PASSWORD 51)
The 75LC comes pre-calibrated to read proper temperature with Automatic Scale Conversion from F to C. Calibration
parameter provides a means for offsetting the displayed temperature by +/-5 if so desired. NOTE: CALIBRATING offset doesn’t
change setpoints
RINGBACK DELAY (PASSWORD 56)
Ringback generates timed repeat audible alarms during an ongoing temperature or power failure alarm condition. Select
desired time interval for this to occur.
LIGHTS OFF DELAY (PASSWORD 57)
The lights will turn OFF after the pre-programmed time. Factory default time is 14 minutes - Field programmable
LIGHTS OPERATION (PASSWORD 58)
“Aut” operation provides Timed Lighting with Auto panic. "tL” operation provides regular timed lighting.
ALARM RELAY (PASSWORD 59)
Normally Open (N/O) and Normally Closed (N/C) dry contacts are provided for low voltage of 28-30VDC at 1 amp. For main
voltages, 120/240VAC, an external relay will be required with 28-30VDC at 1A. To control main voltages, 120/240VAC, an
external relay will be required.
The two Relay Modes are:
UNLATCHED: Default Setting. Relay activates when alarm occurs and deactivates when Silence is pressed. Typical Application:
Controlling a remote buzzer or light.
LATCHED: Relay activates when alarm occurs and deactivates when alarm condition has been cleared and Silence has
been pressed. Typical Application: Connection to a building management system where relay remains activated until alarm
condition clears and is acknowledged.
