3)
Run the probe into the monitored compartment and locate the sensor in a spot which will typify the
average ambient temperature. Recommended location is in front of the blower on the ceiling in the
center of the room. Make sure that the sensor and sensor wire is positioned so that it will not be
damaged by any products or items in the monitored area. Fasten the probe with the provided 3/8”
clamp. (NOTE: If desired, the sensor wire can be lengthened hundreds of feet using ordinary
thermostat wire without affecting accuracy of the displayed temperature. It can be shortened as
well. If this is necessary, proper polarity must be observed when reconnecting probe. i.e., white to
white & black to black. If a splice is made in the monitored compartment, seal with silicone to
prevent moisture from causing erroneous temperature readings. Also, if probe is extended into
monitored compartment through back wall of alarm, seal opening to prevent moisture from
entering alarm. SPECIAL NOTE: DO NOT RUN SENSOR LINE FOR EXTENDED
DISTANCES IN CONDUIT WITH HIGH VOLTAGE OR “BOUNCING” OR ERRONEOUS
READINGS WILL RESULT!)
4)
Bring AC Power (110VAC Standard) 220VAC Optional if so ordered) through suitable conduit to
the hole in the top of the enclosure. Connect to the black & white #18 wires which are located in
the small compartment above the actual alarm unit. Insulate the splice and tuck the wires back into
the compartment.
SETTING UP THE ALARM
1)
Provide power to the alarm unit. If horn is sounding, throw ALARM CONTROL SWITCH
to opposite position.
2)
Digital Readout blinks when power is first applied or whenever power is interrupted and
restored. Stop the readout from blinking by sliding the DISPLAY RESET SWITCH to the left
position and then releasing.
3)
Select Fahrenheit or Centigrade with the DISPLAY MODE SWITCH. Left is Fahrenheit.
Right is Centigrade.
4)
Select the alarm setpoints with the SETPOINT DISPLAY SWITCH and the SETPOINT
ADJUSTMENT CONTROLS. The selected setpoint will display on the Digital Readout.
(Standard setpoint range is -40F to 120F or -40C to 49C. Other ranges available on request.)
5)
Select length of time delay desired with TIME DELAY SELECT SWITCH. This switch
matrix provides four switches which may be used singly or in combination to produce any time
delay desired from 10 minutes to 150 minutes in 10 minute increments. (Other ranges available on
request.) A switch is selected if the top of the rocker is pushed in. See drawing on following page:
IMPORTANT!! AT LEAST ONE TIME DELAY SWITCH MUST BE SELECTED OR
THE ALARM WILL NOT FUNCTION PROPERLY
