Page 4: Introduction
Introduction General Description The Brasch Environmental Technologies GSE Generation 2 Gas Detector is designed to function as a dual-zone standalone gas monitor and ventilation controller. The detector consists of a sensor (or sensors), six control relays, and digital control circuitry. The unit monitors the signal from the sensor, compares the signal to preset values, and controls relay contacts based upon the comparison. -

Page 9: Operation Safety Notice
Operation Safety Notice Certain procedures and operations detailed in this manual require that specific precautions be taken prior to beginning the procedure or operation. When precautions are required, a notice will be printed in an appropriate location in the manual. The user is urged to read and understand all such notices. -
Page 10: Quick Start Guide
Operation with the wrong power requirement will void the manufacturer’s warranty and the installer will be responsible for any damage that occurs. Contact Brasch Environmental Technologies, LLC before connecting power to the detector if you are unsure of the correct power requirement. IOM01... -
Page 11: Step 3 - Remote Transmitter Wiring
CAUTION It is very important that the power and signal connections between each transmitter and between the transmitters and the Brasch controller be correct. If the connections are wired incorrectly, damage to both the transmitters and the controller will occur. -
Page 12: Step 4 - Relay Wiring
Step 4 – Relay Wiring In most cases, wiring of the ventilation control relays can be completed without opening the front panel of the detector. Color-coded wires connected to the internal relay terminals extend outside the housing through the conduit connector located at the top, left of the unit. Use only the necessary wires required for control of the ventilation components. -

and sensors are present. Upon sensors exiting warm-up, the dashes will be replaced by a numeric readout of the gas concentration or any errors present. See page 18 for more information concerning the initial startup. Step 7 – Self-Test Mode This detector is equipped with a self-test mode that can be activated any time after warm-up by pressing the “SELF TEST”... -
Page 14: Installation
Installation Mounting the Detector The ability of the detector to sense the target gas and efficiently control the ventilation system depends greatly upon proper selection of the mounting location. This detector monitors the area around it by sampling the air that passes by the sensor. Since the sensor is mounted inside a housing, air must diffuse through the intake vents and pass by the sensor on its way out the exhaust vents. -
Page 15: Connecting The Power Supply
Only qualified personnel should attempt to install, maintain, or service this equipment. Brasch Gas Detectors are designed to operate from either 120 VAC or 24 VAC. Selection of the operating voltage is made by the user at the time the detector is ordered. The correct voltage is listed on the front panel label. - Page 16 Contact Brasch Environmental Technologies, LLC before connecting power to the detector if you are unsure of the correct power requirement. Color-coded wires exiting the detector housing through the top, right conduit connector are provided for connecting the operating voltage to the detector.

Page 17: Connecting The Remote Transmitters
RS-485 termination resistor (SW3) to reduce signal reflections. Connecting the Ventilation System As an energy saving device, the main function of the Brasch Gas Detector is to operate the ventilation system only when necessary. To accomplish this, the detector is equipped with three dry-contact control relays per zone with color-coded wires exiting the detector housing through the top, left conduit connector. -
Page 18: Connecting The External Alarm
Then slide it back on the pins. Connecting the External Alarm The Brasch Gas Detector comes standard with an internally mounted alarm. If the target gas concentration exceeds the Alarm threshold, this alarm will sound. There is also a set of external Alarm contacts that close at the same time. -
Page 19: Using The Self-Test Feature
14. Activates the internal alarm for 3 seconds 15. Resumes normal operation Before using the self-test feature, Brasch recommends testing the ventilation system wiring for correct connections and operating the ventilation components manually. Make any wiring changes and replace any defective components. Any problems found during the self-test can then be identified much easier. -

Page 23: Operation
Operation How the Detector Senses the Target Gas Ambient air surrounding the detector housing diffuses inside the housing where it comes into contact with the sensor. Although the detector’s circuitry dissipates very little power, a small amount of heat is produced inside the housing. This heat causes air to rise up through the bottom vents, past the sensor(s), and out the upper vents on either side of the unit. -
Page 24: Alarm
target gas concentration rise quicker than the Low Alert delay time, the High Alert condition will be activated immediately, regardless of how much time is left in the delay period. If the unit is set for “50/100” operation, both the Low Alert and High Alert relays will close simultaneously. The High Alert relay will remain closed until the target gas concentration drops below the Low Alert threshold. -

Page 26: Adjusting The Settings
Adjusting the Settings Note All changes made to the control board settings require a power cycle to take effect. Sensor Address The sensor address is set by SW1 on the top, right side of each sensor board using a binary counting system. -

Page 28: Obtaining The Best Operation
18 on page 49 of this manual. As an example, a Brasch Carbon Monoxide Detector has a full scale output of 200 PPM CO. For the 4-20 mA output mode, 0 PPM CO would equal 4 mA while 200 PPM CO would equal 20 mA. - Page 29 are adjustable in eight steps using the corresponding rotary switches located on the control board. The threshold sets a desired maximum concentration while the delay assures that transient levels of gas do not cause the fans to operate for unnecessarily short periods of time. This delay for any target gas is adjustable from 0 to 7 minutes in eight steps of one minute each.

Page 30: Maintenance
100% response. If the response time is too slow or the concentration displayed is outside of acceptable tolerance, the sensor should be recalibrated or replaced. To ensure proper response and accuracy, Brasch Environmental Technologies recommends testing oxygen and toxic detectors once every six months and combustible detectors once every three months. -
Page 31: Replacing The Sensor
Replacing the Sensor The sensor’s useful lifetime depends greatly upon its operating conditions. Continuous operation around large or numerous gas sources may shorten the sensor’s useful life. A recommended recalibration date is recorded on the front panel label. Please refer to figure 16 in the appendix of this manual while removing and installing the sensor module. -

Page 34: Cannot Run Self-Test - 9802
The most common reason for this error code is improper wiring between the sensor board and control board. Another reason is that the sensor is addressed incorrectly, either matching the designation of another sensor or being set to an address set as inactive on the control board. Cannot Run Self-Test –... -
Page 35: No Active Zones - 9998
No Active Zones – 9998 This error will only appear if there is damage to the zone assignment circuit. It is not possible to achieve this error under normal operating conditions. Replace the control board to correct the error. No Active Sensors – 9999 If all sensors are set as inactive at SW3 on the control board, this error code will appear. -
Page 36: Common Installation/Operation Mistakes
Common Installation/Operation Mistakes Ventilation Components Connected without Control Voltage Relays on this detector are dry contacts. They do not supply any voltage. A typical mistake is to wire ventilation equipment directly to the relay contacts, expecting them to provide the necessary power. -
Page 37: Setting The Proportional Output Incorrectly
emissions detection, smoke from the engine exhaust could build up to a point where people in the area begin to experience irritation in their eyes and nose. Choose a delay setting that activates the fans and begins to clear the area before the gas rises to a dangerous concentration, or eye and nose irritation happens. -
Page 38: Limited Warranty
If service or repair of your Brasch product becomes necessary, an authorization request for returning the product to the Brasch factory must be obtained from our sales office.
