FM-180 Installation Information & Documentation (PDF)


What is the appropriate flange to use when installing the FM-080-3" or FM-180-3" Butterfly valve?

Use an ASME/ANSI 125/150 lb class flange, six bolt positions.

How can I connect the FM-080 or FM-180-3" Butterfly valve to a PVC pipe?

Contractors in the field have reported using a VanStone Loose Ring or similar product to make this type of connection.

I just installed my wireless system. Why am I receiving a low battery / lost signal indication?

The low battery indication on the wireless receiver (black box) serves a dual purpose for both low battery and lost signal. Since all units ship with new batteries, you are likely NOT experiencing low batteries at this time. A true low battery indication would have the low sensor flashing a yellow LED to indicate trouble. Here are the two most common issues we see with these units:

  • Confirm that the batteries are installed correctly in the sensor – refer to Installation Manual Step 12. Etching or markings should be facing up, with battery holder at 12 o’clock. The gold battery terminal on the left shows above the battery when installed properly.
  • Refer to the Functional Test procedure – Step 17 in the Installation Manual. Be sure that all doors are closed between the sensor location and the receiver. Also be sure to step a few feet away from the sensor and the receiver, as your body can act as an antenna, giving a false positive for signal strength. If you find one sensor takes a bit longer than the others to activate the receiver, that sensor may require a Wireless Signal Repeater to assist with signal strength or to triangulate the signal around an interference.

Other, less common issues might be:

  • Users will sometime take sensors offline and store them in a drawer as a spare. Confirm that all the sensors programmed to the receiver have batteries and are in service. The sensors check in with the receiver a few times every hour, and if one goes over 2 hours without a check in, you will get the audible alarm.
  • It’s possible that a sensor got programmed to the receiver here at the factory, and that the sensor did not ship with your receiver (again, in this case you will receive a lost signal indication alarm). You can clear the memory in the receiver by pressing and holding the black teach button (upper right-hand side of the receiver) for 45 seconds. Next, reprogram the sensors to communicate with the receiver: press and release the teach button on the receiver, then press and release the teach button on the sensor. Repeat for each sensor to be deployed.

We hope this information is helpful to you. Please don’t hesitate call us at 888-771-4929 to discuss your particular situation in more detail. Sometimes it’s easier to troubleshoot over the telephone than in writing.

What if my neighbor and I both have wireless systems – will his sensor puck activate my leak detection system?

No. Our wireless radio system is what is known as a paired system. This means that the alarm box is programmed or taught to listen to only the sensor pucks within it’s designated system. So if your neighbor’s wireless system goes into alarm, only his (or her) system will shut down.

How do I add additional sensor pucks to the system?

FM-180 wireless systems follow a simple “teach” step to begin communication between the Alarm Box and Wireless Sensor Pucks.

When I plug in the FM-180 Wireless Signal Repeater (FM-WSR) to a wall outlet, the red indicator light does NOT turn on – is it broken?

No – the red indicator light flashes when the unit is receiving a wireless signal from the sensor puck(s) and passing it along to the wireless receiver/alarm box.

My water main line is only accessible on the exterior of the structure – can I mount the wireless receiver/alarm box outside?

No – we recommend the wireless receiver/alarm box be inside the structure. Most of the FM-180 valves are rated for outdoor use (NEMA 4X), but the wireless receiver should be located inside of the structure. Additional cable extentions are available if necessary to assist you with this type of installation.
