F-Series Heat Alert systems, deployment systems and vehicle bail-out systems are a brand owned and produced by Ray Allen Manufacturing. Based on customer feedback, Ray Allen Manufacturing realized that the available options on the market did not fit the needs of Police K9 and Military K9 users for their vehicles. Though user feedback and continuous development we have created what we feel is the most functionally advanced user-friendly and durable system on the market today. Every function has been tested continuously for over 1 million cycles without a single system failure. Trust that Ray Allen Manufacturing with the F-Series Heat Alert system have your dogs' safety in mind.
