Introducing the LP401, LP401A, LP405, LP405A Propane Gas Detector

The LP401, LP401A, LP405, LP405A Propane Gas Detectors are effective products for detecting any build-up of propane gas in your home. Dicon Global Inc., the maker of these propane gas detectors, has been developing and making products for detecting gases since 1985.

Your new detector:

• Is easy to install
• Monitors for propane gas continuously and sounds a loud (85db) alarm when it detects a build-up of propane gas.
• Has a Test button so that you can test it at any time.
• Tests itself continuously
• Is listed by Underwriters Laboratories to UL1484 standard
• Has a 5-year guarantee for the propane gas sensing element.

Why should you be concernedabout propane gas?

Propane gas is a colorless, flammable gas that can be explosive if it escapes and builds up.
Propane is stored as a liquid under pressure, so most likely sources of leaks are in the connections to propane tanks for propane-powered heaters, stoves, refrigerators, furnaces, and barbecues. When propane leaks, it becomes a gas and can be ignited by a spark or flame.

Where should you install thedetector?

Propane gas is heavier than air and therefore collects in the lowest areas of rooms and homes. To detect a dangerous concentration of propane gas, you should place your detector near a propane appliance. You should also place detectors on floors that are below the floor with a propane appliance. For example, a leak in a kitchen can create a build-up of propane in the basement.
You should install your detector as close to the floor as possible.

How should you install thedetector?

You must install the LP401, LP401A, LP405, LP405A Propane Gas Detector on a wall as close to the floor as possible.

To install the detector:

1. At the place where you are going to installthe detector, draw a horizontal line four inches long.
2. Place the circular mounting plate so that thesquare holes are aligned on the line.
3. In each of the circular slots. Draw a mark tolocate a mounting plug and screw.
   
   
4. Remove the mounting plate.
5. Using the appropriate size drill, drill twoholes at the marks and insert wall plugs.
6. Using the two screws and wall plugs (allsupplied), attach the mounting plate to the wall ensuring that the cord slot in the mounting plate is down.
   
   
7. Slide the detector onto the mounting plateso that the two arms on the mounting plate fit into two slots in the back of the detector.
   
   
8. Ensure that the detector's 12 Volt wires are located in the cord slot or behind the detector in an appropriately recessed area.
   
   
9. Give the detector a short counter-clockwisetwist to lock the detector in place. If the detector is not horizontal, you can remove it, readjust the mounting plate, and re-install it until it is horizontal.
10. Connect the 12 Volt source using the two connectors supplied.
11. (Models LP401A and LP405A only) connect the three relay output wires (from the back of the detector) using the connectors supplied. The relay output wires have the following connections and are labeled as such:

• the black wire is common
• the red wire is from the normally-open contact.
• the green wire is from the normally-closed contact

Note: Steps 10 and 11 must be preformed by qualified service personnel only.

Ensure that any wires not connected are insulated with a connector (supplied).

Wait for ten minutes before you test the detector. During that time, the alarm may sound several times and the yellow (malfunction) lights may light up once or twice as the detector cleans the sensor. This will also occur if the power to the detector is interrupted.

How can you test the detector?

To test the detector, wait at least ten minutes after installing it, press the test button. The alarm sounds.
To reset the alarm, turn the 12 Volt supply off, wait ten seconds, then turn it on again.
The detector continually checks itself. If it finds a malfunction, it lights the yellow light. If this occurs, call Dicon Global Inc. at 1-800-3874219.

How can you maintain yourdetector?

A detector is only useful if it works. To keep it working, all you need to do is:

• vacuum the air vents occasionally to keep them free of dust.
• test the detector by pressing the test button once a month.

What do the lights mean?

The detector has three lights:

Green (Power) light: This lights up when the detector has power. It is normal for this light to be on while the detector is powered.

Red (Alarm) light: This lights up when the alarm sounds. It is normal for this light to turn on when you press the Test button.

Yellow (Malfunction) light: This lights up when a detector finds a malfunction while it is checking itself. It is normal for this light to turn on once or twice after you power the detector or after a power failure.

What should you do if the ALARM sounds?

EVACUATE IMMEDIATELY!

Do a head count to check that everybody is accounted for. Call the nearest fire department and ask them to determine the source of propane gas. Do not re-enter the premises until the problem has been corrected and the propane gas has been dispersed.

Activation of this device indicates the presence of propane gas, which is flammable and can be fatal. The source of the gas may be an object such as a furnace, a hot water heater or other propane gas appliances.

This detector will only indicate the presence of propane gas near the detector. Propane gas may be present in other areas. Correction of the problem may require the services of a local propane gas utility company or contractor.

What do you do after the problem has been corrected?

On re-entering the premises after an alarm:

1. Turn the 12 Volt supply off for ten seconds, and then turn it on again.
2. After ten minutes (during which the alarm may sound once or twice and the yellow light may flash), test the detector to make sure that the detector is working properly.

Technical Information

Your LP401, LP401A, LP405, LP405A Propane Gas Detector uses a sensing technology that enables the detector to sound an alarm before concentration of gas reaches 25% of the Lower Explosive Limit (LEL).

Exposure times

The propane gas concentrations standard for the alarms has been set by the Underwriters Laboratories Inc. to be less than 25% of the LEL.Therefore your unit will alarm immediately, upon detection of dangerous levels.
