Trouble Shooting:
a. The receiver rings without the PIR sensor being triggered.
Answer: The receiver may be matching on the same frequency with nearby PIR sensors. You should reset the pairing and re-pair your PIR sensors.
b. There is no ring/LED flash when the PIR sensor is triggered.
Answer:
• Check whether the batteries (AAA) are inserted in the PIR sensor.
• If the receiver is powered by batteries, check whether batteries (Type C batteries) are inserted in the receiver.
• If the receiver is powered by an adapter, check whether the power outlet being used for the adapter is working properly.
• Check whether you have turned on the receiver.
• Pair the receiver and PIR sensor again.
c. The ringtone/alarm volume is greatly reduced.
Answer: A weak battery can reduce the ring volume. Change the batteries every 10-12 months. Metal constructions, walls, and other appliances with the same frequency can also affect the receiver’s ringing. Avoid mounting the PIR sensor and receiver near any metal objects.
