I have a Risco G Tag wireless alarm and I am receiving the following message. Back door show b. The alarm will not set properly and I have to input the code twice to turn off the exterior and interior buzzers. Can anyone advice me how to sort this £

Battery requires to be replaced in back door sensor. I'd do all sensors batteries at the same time. If doing it yourself be aware it may be set for engineer reset for the tamper when you open the devices and you will be unable to reset it without engineer code. If unsure get someone on.
