SAE-1101/1102/1151/1152 Carbon Monoxide (CO) Detectors 3 Installation Guide
Set-Up
Warm-Up
1. Verify that the detector is properly wired and all
connections are tight.
2. Apply power.
If an LCD display option is installed, it will indi-
cate the software version number and then begin a
warm-up period. During the warm-up, the output is
fixed at 4 mA or 0 VDC and the relays are off. After
the warm-up period, the sensor will begin reading
the CO level, output the correct analog signal, and
display the value on the LCD.
Operation
In normal operation, the sensor measures the CO
level in the surrounding air and displays this value
on the LCD (IEI-1001) if present. The measurement
range is 0 to 300 ppm. The analog output is propor-
tional to the measured concentration of CO. The
signal type must be selected during installation via
the jumpers. One jumper selects either 4–20 mA or
voltage output, and if voltage is selected, the other
jumper determines the full scale value as either 5 or
10 VDC.
Two optional relays (in
SAE-1102/1152 models) are
used to indicate alarm conditions. The trip point,
hysteresis, and delay time of each relay can be pro-
grammed. For example, the first relay defaults to 50
ppm trip point, 10 ppm hysteresis (deadband), and
2 minute delay time. Values can be changed via the
Normal (Configuration) menu (when an IEI-1001 is
installed). In this example, a timer is started when
the CO level exceeds 50 ppm (the trip level). If the
level drops below 50 ppm before 2 minutes (the
delay time) has expired then the relay is not acti-
vated. If the CO level exceeds 50 ppm for 2 minutes,
the relay is activated. The relay will remain activated
until the CO level drops below 40 ppm (hysteresis/
deadband trip level). This relay can be used to signal
a “low alarm.” The second relay operates in the same
manner and has independently programmable trip
point, hysteresis, and delay time. This relay can be
used to signal a “high alarm.”
The optional buzzer (in
SAE-1102/1152 models) trip
point and delay time can be programmed similarly
to the relays to indicate an alarm condition. When
the trip point is exceeded for a time longer than the
delay time, then the buzzer will sound until the CO
level falls below the trip point. The buzzer can be
disabled in the Normal Menu.
Menu Configuration/Testing/Calibration
NOTE: These instructions apply to units
manufactured after the corresponding
dates shown in the Models list. For older
units (with a row of LEDs on the left side
of the board), see the original version of
this installation guide available on www.
kmccontrols.com.
Navigating Menus (LCD Display Required)
NOTE: The IEI-1001 LCD display module can be
temporarily installed for configuration and
then moved among different compatible
detectors. Otherwise, the default
configuration must be accepted.
The menus may be accessed any time after the initial
warm-up period. The menus are used for setup,
testing and calibration and are controlled by using
the three buttons on the circuit board labeled MENU,
ROLL, and SAVE.
Press and release the MENU button to enter the
configuration menu. Then press the MENU button
to step through the selections.
Use the ROLL button to make changes.
The SAVE button saves the current setting to
memory, exits the current menu (with the excep-
tions below), and returns to normal operation.
There are three sub-menus available from the Main
Menu as shown below. Press and release the MENU
button to enter the Main Menu.
NOTE: The SAE-1100/1150 series detectors do not
have the Modbus option that displays on the
menu.
1. NORMAL (CONFIGURATION) MENU: Press
the SAVE button here to enter.
Press the MENU button.
2. TEST MENU: Press the SAVE button here to
enter.
Press the MENU button.
3. CALIBRATION MENU: Press the SAVE button
here to enter.
Press the MENU button. Returns to normal
operation.
