For proper use, see supervisor or User manual, or call Kele Technical Service at 877-826-9045. KGC-120 may not function effectively below 32°F (0°C) or above 120°F (49°C). Using the equipment outside of this temperature range may adversely affect product.
The KGC-120 exhaust fan controller, in conjunction with Kele™ gas detector, controller, transducers, provides automatic controls to help maintain an acceptable environment in parking garages or other facilities. The KGC-120 system is designed to meet specifications for safety in enclosed parking garages, including the Uniform Building Code and OSHA 50ppm CO requirements.
ETL Listed to UL 2017 (Type SM) Where required by federal, state, local regulations or the Authority Having Jurisdiction, KGC-120 is required to be used with Listed Horn/Strobe model 78-2900-0211-X* to meet the 85dB(A) Audibility requirements of Standards UL 2017.
3.2 Mounting Mounting holes are provided in the KGC-120 case at the four corners. The top two are keyhole shaped so that the panel can be hung and then the two bottom screws driven to hold the panel. See figure 2-1. The panel should be mounted with sufficient space all around for access to Conduit entry holes provided on the top, bottom and right side of the panel.
(see the User Instructions of each sensor type for location and coverage details). Extra sensors may be needed near areas where people work, such as toll booths. Kele provides only the control panels and sensors. Fans, relays, and other devices are provided by the contractor.
AC power connections must be bundled with the KGC-120 sensor cables, the sensor connections should be made with two twisted pairs of the appropriate gauge, with an overall foil and braid shield. All shields should be terminated at the KGC-120 end of the cable only.
Figure 3-4 Sensor Interface Connection – Channels 5 and 6 Note: If CX-6 (CO and NO dual sensor) is connected to Channel X in KGC-120 then address X is assigned to NO sensor and address “X+12” is assigned to CO Sensor.

R1 R2 R3 is a 9-position variant of the high voltage modular connector used for power input.
Immediately exit any environment that causes an alarm condition on the sensor. 3.3.6 Interfacing Kele Sensors Kele sensors with current loop outputs may be used with the KGC-120. See Kele.com for information on compatible Kele gas transducers. See specific information on other manufacturer’s transducers.

Power connections to Kele sensors used with the KGC-120 are polarity-insensitive (no polarity), since a bridge rectifier is connected to the power input terminals. All sensors used with the KGC-120 panel employ screw clamp terminal blocks for power and signal connections. Polarity of the current loop connections is marked on the modular connector of the sensor.
4.1 Power up When power is first applied to the KGC-120, a few simple self-tests will be performed, and the system will cycle through all status lights, and display the system name and model # (Figure 3-1). The system will then proceed to normal mode, if the operating parameters have been entered.
The keypad is used to select the information displayed and to enter the configuration parameters, which are stored in the KGC-120 memory. The keypad consists of the usual ten-digit keys, four direction keys, plus a MENU key that is used to access the configuration menu and a HUSH key that will silence the audible alarm indicators.
Figure 4-5 Sensor prompt In this example, the first digit entered was 1. Since the KGC-120 can handle 12 sensors, the first digit for a sensor number is either 0 or 1. The leading zero must be entered when selecting a sensor less than ten. When the second digit is entered, the normal display will be restored;...
Kele Gas Controller KGC-120 Operation Manual Figure 4-6 Alarm display The display will cycle through all sensors that are signaling alarm levels, at five seconds per display. Pressing any key (except HUSH) will advance the display to the next sensor that is signaling an alarm level.
Kele Gas Controller KGC-120 Operation Manual When the HUSH key is pressed, the internal buzzer will be silenced for fifteen (15) minutes. If the horn or strobe turn on delays have not finished, then they will also be silenced. If the delays have finished, the HUSH key must be held for three (3) seconds in order to silence the horn and strobe.
Kele Gas Controller KGC-120 Operation Manual 4.7 Ventilation Control The ventilation control function operates independently from the alarm function. It provides the ability to configure the KGC- 120 for control of one to three zones. Each zone can respond to gas levels indicated by one or more of the sensors, with configurable turn on and turn off concentrations (rising and falling) for each gas type.
While the KGC-120 is in the configuration mode, alarm and ventilation control functions continue in the background with the previously set configuration values. If an alarm condition is detected, the alarm lamp, the buzzer, the horn and the strobe will operate as configured but the LCD will not display the detailed information.

KGC-120 will remain in normal mode. When new registration information is detected by the KGC- 120, for example if a different gas type of Kele sensor was installed, the following message is displayed: “Configuration Changed Any key to save” is displayed.

Kele Gas Controller KGC-120 Operation Manual The default minimum on time is one minute and the maximum allowed value is fifteen minutes. 4.8.5 Configure Horn Submenu The configuration parameters for the horn are similar to those for relays. A horn would not normally require a minimum on time, but this parameter allows a more versatile configuration.
4.8.7 Configure Zones Submenu The KGC-120 ventilation control can support up to three zones. The zone functionality makes the KGC-120 very flexible. For example, each zone can be configured to monitor a separate set of four sensors and control a single relay.

These patterns are selectable by the installer using this group of submenus. Once again, the left and right keys will scroll through the signal types and the up and down keys will scroll to the signal sources.

Kele sensors may be tested by depressing the TEST button on the sensor printed circuit board, or (depending on the type of sensor), the button on the interior front panel of the unit. Kele sensors will step the output current level from 4 mA to 20 mA over the course of the warm-up period, allowing the technician to determine where the trouble condition exists.
When using the timed ventilation mode, the system clock should be checked regularly (at least twice a year). The battery backed real time clock in the KGC-120 does not adjust for daylight saving time so the spring and fall switch over points are good choices to check the system clock.

6.1.2 Functionality Test Turn off the KGC-120. For KGC-120 move the jumper from bottom two pins of EXT connector to pins 1 and 2 of EXT connector. For KGC- 120, move the jumper in J10 to left two pins of J10.
Note: The Delay Time default is 1 minute. If the duration of a test procedure or gas exposure is less than 1 minute, the relays, horns, and strobes may not engage even though the KGC-120 display and the sensors respond. When testing the system disable the delay (set Delay Time to zero minutes/seconds).
