Linear Mega Code ACT-22B block coded 3 channel remote, 318 mhz, keychain style acp00616a The Model ACT-22B 3-Channel Block Coded Key Ring Transmitter is designed for use with Linear's access control products. The Model ACT-22B is a three-channel device. Pressing the transmitter's left or right front button sends channel one or two. Pressing both buttons sends channel three. Lithium batteries with a five-year service life are included and the transmitter is supplied with a quick-disconnect key ring. A unique 10-second time-out feature prevents the system from being shut down by a single transmitter transmitting continuously. The transmitter is MegaCode format, which means each transmitter is factory preprogrammed with one of over 1,000,000 codes, virtually eliminating the possibility of code duplication. Because the receiver "learns" each specific code, no unauthorized person can gain access to the system by reprogramming a transmitter. Block coded transmitters are factory programmed to a sequential series of transmitter ID codes. When used with a Linear access controller, transmitters can be locally or remotely programmed into memory by entering the first and last codes of the block into the system. Facility codes can be selected to further customize the system.
I purchased 2 of these garage door remotes to have extras, to keep in the pouches of my motorcycles. They are easy to program and I love the small size. They're perfect to keep on the motorcycles and I no longer have to grab the larger remote from my truck when I go on a bike ride. Thanks Gatehouse!!
