Keeping the Old Systems Running like New!
My home combo Fire/Security system is over 25yrs old. I know, that's pretty old. However, it still reliable, works well and does the job I need. Having companies on Ebay who still sell these peripheral devices like smoke detectors allows me to keep my home safe and system running. System Sensor by Honeywell are solid quality products at reasonable cost.Verified purchase: YesCondition: New
