SOS Siren Yelp Noise Tester/Troubleshooting

Yelp Signal Sensor

SOS Siren Sensors are a cheap and effective way to allow emergency vehicles passage through the gate without the need of ramming the gate. The sensor will detect the sound and automatically send the signal to open the gate within 3 seconds. This is an effective tool to maintain the safety and security of the perimeter in case an emergency vehicle needs to get through the access gate.

Below is a siren tone that can be used to test your SOS unit. The "Yelp" is a specific tone the emergency sirens can make. There are many tones that emergency vehicles can make, but the sensor will only respond to the "Yelp" signal.

To begin, turn the sensitivity dial to 8.5 and play the Yelp Siren from your phone close to the microphone. The power/sound light on the board should turn solid, and the gate should open within 3 seconds. Now, turn the sensitivity dial back down.

If the gate does not open, please refer to the troubleshooting guide. The gate owner should request a live test from an emergency responder annually. This is for testing purposes as well as training new emergency responders on how to open a perimeter gate using their Yelp Siren.
