Set of Delkim alarms. I believe they may have been the first in their TXI remote range (happy to stand corrected though). One blue, yellow and green. No remote. Blue is in full working order Yellow is in full working order Green is working but has a couple of issues: - led is not working - sensitivity switch will not stay on plus. Works fine on minus. Came as part of a bundle but not needed hence selling.
