SAE-1111/1112 Space Mount

Install the unit at least ve feet above the nished

oor of the area to be controlled. Do not install

near doors, windows, supply air diusers of other

known air disturbances. Avoid areas prone to vibra-

tion or rapid temperature change.

1. On the mounting surface, mark and drill the four

mounting holes (for screws) and remove any

debris from all holes.

2. Aach the unit to the surface by threading four

screws through the four mounting holes.

3. Remove the two cover screws (if installed),

release the latch, and swing open the cover.

4. Insert wiring through a knockout.

5. After wiring, conguring, and testing the

unit (see later sections), close the cover and

(optionally) secure it with two (supplied) self-

tapping screws.

SAE-1162 Duct Mount

Choose a mounting location in a straight section of

a return air duct. Mount at least 5 feet (or 7.5 duct

diameters) from corners and other items that may

cause disturbances in the air ow. Avoid areas prone

to vibration or rapid temperature change.

1. Cut a 1-1/8 or 1-1/4 inch hole in the duct for the

air sampling probe.

2. Insert the probe through the hole, align the unit

so that the duct air ow is parallel with the side

vent holes in the probe (air ows directly into

the probe holes), and mark the four enclosure

mounting holes.

3. Drill the four mounting holes (for screws) and

remove any debris from all holes.

4 . Insert the sampling probe into the duct.

5. Aach the unit to the ductwork by threading four

screws through the four holes on the outside of

the enclosure.

6. Remove the two cover screws (if installed),

release the latch, and swing open the cover.

7. Insert wiring through a knockout. After wiring a

duct sensor, ll the knockout hole with plumber’s

Wiring Use 22 AWG shielded wiring for all connections. Do not locate device wires in the same conduit with wiring used to supply inductive loads. 1. Connect the positive DC voltage, or the hot side of the AC voltage, to the terminal marked POWER (but do not apply power until all wiring is completed and Volt/mA position is selected). 2. Connect the power supply common to the terminal marked COM. The device is reverse voltage protected and will not operate if connected backwards.
PAGE 3
NOTE: The sets of optional (form “C”) relays feature Normally Open (NO), Normally Closed (NC), and Common (COM) terminals. The relay output is completely isolated. The COM terminal is NOT connected to the signal or power supply COMMON terminal. (The contacts are rated at 5 A @ 250 VAC, 5 A @ 30 VDC, power factor = 1.) NOTE: Pressing the TEST button (when enabled) tests the buzzer, analog output, and relays. The Test function may also be initiated remotely by shorting the TEST + and TEST – terminals.

switch on the front cover (or activate the remote TEST input) when the CO level is below the alarm level (minus the hysteresis/deadband). WARNING All commercial CO sensors have a finite life. The life expectancy of these models is 5 to 7 years. They must be replaced periodically to ensure reliable operation in detecting conditions that are potentially hazardous to human health and safety. The Manual Reset also applies to the buzzer alarm.

Press
Relay 1 TRIP = 50 Use the key to scroll through the available options. The Relay 1 alarm trip point may be set from 20 to 500 ppm in 10 ppm increments. Press to save the setting. The factory default is 50 ppm. (This item will not be shown if Relay 1 is not installed.) When a value is changed, press the key to save it to memory and advance to the next menu item. Press CO Range = 0–300 ppm Press the key to scroll through the available options.

Press
Relay 2 Hyst = 20 Use the key to scroll through the available options. The Relay 2 hysteresis (deadband) may be set from 10 to 100 ppm in 5 ppm increments. Press to save the setting. The factory default is 20 ppm. Note that the maximum value may be limited by the trip-point value. (This item will not be shown if Relay 2 is not installed.) Press Fault Md = Disable Use the key to select Enable, Disable, or Reset.

Press
ReCal Md Time = 1yr This is used to set the CO sensor recalibration interval. Use the key to set the ReCal mode timer to 1, 2, or 3 years. The default is 1 year. Press to save the setting. (This item is not shown if the ReCal mode is disabled.) Press BackLite = Enable Use the key to enable or disable the LCD backlight. The backlight is always on when enabled and always off when disabled. Press to save the setting. The factory default is Enable.
PAGE 8
Calibration NOTE: The sensor must be continuously powered for at least 1/2 hour prior to calibration. The sensor may also be calibrated or verified with CO gas as needed. This requires a field calibration kit consisting of a bottle of gas (e.g., 250 ppm CO), a tank pressure regulator with flow restrictor, and the necessary tubing to supply the gas into the sensor. Calibration can be done at 68–80° F (20–27° C). The device cover must be opened to perform an actual calibration.
