Page 8: Installation
3.1 Mounting of Instrument The GSM-60 should be located near the air to be monitored. Sampling lines should be no more than 50 feet long. It is recommended that Teflon® (PTFE) lined tubing be used. Quick disconnect fittings are supplied for use with 1/8” ID tubing. -
Page 9: Power Supply
The instrument may go into alarm briefly, but the sensors stabilize quickly. If the instrument persists in alarm, acknowledge the alarm by pressing the switch. If alarm persists longer than 30 minutes, call ENMET AUDIO DEFEAT ALARM ACKNOWLEDGE customer service personnel. -
Page 10: Sensor/Transmitter Connection
If you have a question involving the location of a unit or sensor, please contact your distributor or ENMET personnel. A technician will analyze the question and recommend a location. -
Page 11: Optional 4-20Ma Outputs
These relay contacts can be used to operate auxiliary alarms or other functions. It is recommended that power for auxiliary equipment be supplied from an independent power source, separate from the GSM-60. Place a hole in the enclosure for a wire exit, and use appropriate cable fittings. -
Page 12: Operation
4.1 Normal Operation Condition With the GSM-60 installed as described in Section 3, and in clean air, the POWER green LED is on, the display is lit and the information on the display is as shown in Figure 4 Display, for the sensor(s) installed in the GSM-60. The red alarm and fault LEDs are not lit. -
Page 13: Alarm Latching Or Differential Settings
Differential Setting The Alarm 1 differential value is the delay of the GSM-60 staying in alarm condition until after the measured reading has returned past the alarm point by the differential value. Example: If the alarm point is Λ 10 and the differential is 2, the GSM- 60 will go into alarm at 10 and stay in alarm until the reading has dropped below 8. -

Page 15: Fault Indications
4.8 Hydrocarbon Sensor Response If a Hydrocarbon (HC) sensor is supplied with the GSM-60 instrument, it designed to detect hydrocarbon gases and vapors with an ionization potential (IP) of 10.6 eV or less. Hydrocarbons with an IP of greater than 10.6 eV will NOT be detected. Please see Appendix B for a list of common gases and vapors and their respective IP rating. -
Page 16: Maintenance
: Never spray a cleaning solution on the surfaces of the GSM-60 devices. AUTION Clean the exterior of the GSM-60 enclosures with a mild soap solution on a clean, damp cloth. Do not soak the cloth with solution so that moisture drips onto, or lingers on, external surfaces. -
