General description & intended use

DANGER: If you smell natural gas, evacuate the area immediately, then call 911. Do not wait for the gas leak alarm to sound or for your gas utility to receive an automated notification.

This Gas Alarm is designed to detect natural gas. Natural gas is a fossil fuel that is primarily made up of methane. It is commonly used for cooking, home heating and water heating. Natural gas is typically supplied through a gas main and utility service line connected to your home.

Natural gas is odorless and colorless, but has a chemical odorant (mercaptan) added to it to give it a distinct “rotten eggs” smell. Even odorized natural gas may not be detected by smell in an unoccupied space, by an individual with reduced sensitivity to smell, or in other situations. Natural gas is a highly flammable chemical compound. Although it happens rarely, a natural gas leak can occur inside a house or building. This can be dangerous because it increases risk of explosion and fire. The Gas Alarm is designed to activate a gas leak alarm when it detects 10% or greater of the LEL for methane, which is 0.5% or greater of methane in air.

When the gas leak alarm activates, the Gas Alarm will beep 4 times and state “Danger – gas leak explosion risk – evacuate, then call 911.” followed by 4 additional beeps and state “Peligro – riesgo de explosión por fuga de gas – evacuar, luego llamar al 911.” In the event of a gas leak, you may smell natural gas before the gas leak alarm is activated. If you smell natural gas at any time, do not wait for the gas leak alarm to sound or check for Gas Alarm malfunction. Evacuate immediately, then call 911.

Using the INS communications module, the Gas Alarm is designed to automatically send Gas Alarm-related information to your gas utility. When natural gas is detected at or above the gas leak alarm threshold, the Gas Alarm is designed to transmit a gas leak alarm notification to your gas utility. The Gas Alarm is also designed to send information about device health to your gas utility during automated health checks performed every 8 hours.

The Gas Alarm is not guaranteed to prevent personal injuries or property damage associated with a gas leak. For example, an error may occur that prevents detection of natural gas, including gas leaks. Network or power outages may prevent your gas utility from receiving or processing automated notifications from your Gas Alarm, including notifications related to gas leak alarms. Some people may sleep through and not hear the audible gas leak alarm. You should ensure that your natural gas appliances and piping systems are properly installed, used, and maintained to reduce the likelihood of a natural gas leak.

• Take immediate action if the Gas Alarm fails a test.

Testing power

• Press test button until you hear a “Beep” sound, then quickly release (within 10 seconds after pressing the test button).
• If the device is properly powered, the green LED will flash twice every second (for 3 seconds) to indicate that the power is on.

Testing gas leak alarm notifications

• Press test button until you hear a “Beep” sound, then continue to hold until you hear a “Beep Beep” sound approximately 10 seconds later.
• Release within 30 seconds of pressing the test button.

If the Gas Alarm is operating properly, the red LED will flash once every 2 seconds for a 12 second period, and the following alarm message will sound: “Beep Beep Beep Beep Danger – gas leak explosion risk – evacuate, then call 911.” followed by “Bip Bip Bip Bip Peligro – riesgo de explosión por fuma de gas – evacuar, luego llamar al 911.”

Testing automated communications

Press and hold test button for at least 30 seconds, until you have heard a single “Beep” followed by a double beep (“Beep Beep”) followed by a triple beep (“Beep Beep Beep”). This will enable communications test mode, and the green LED will flash 3 times per second for as long as you are in communications test mode.

Once in communications test mode, press the test button additional times to test whether the Gas Alarm is communicating normally with your gas utility’s systems, able to properly transmit Gas Alarm error signals, and able to properly transmit a low battery signal. Success will be indicated as follows:

| Green LED| Yellow LED
---|---|---
Communications test mode activated| Flashes 3x per second| Off
1st press: normal communication| Flashes 2x per second| Off
2nd press: proper transmission of device error signal| Flashes 2x per second| Flashes 3x per second
