RioRand Wired Auto-dialer Burglar Security House Alarm System w/ microphone Microcomputer Design

Llego a tiempo, muy recomendado

This autodialer will work once you figure out the instructions. I found a translated version on line. If you are an electronics tech, its use will be a slight challenge. If you need detailed American English instructions, the translated version found online may be a challenge, but not impossible.There is no online or phone support. NOTE: Nowhere is there mention that it does not come with the required 12V power supply, and it will not power without it. It does not have or require batteries. It seems to be made to connect directly to your home alarm system--both power and sensor. But it can use any other sensors: i.e.; NO, NC or don't care (voltage). Mine replace a 30 year old cassette driven auto calling unit that did not have tone calling. This unit only gives 20 seconds for the message (say little and talk fast).

This dialer don't work. After i wiring dialer i can't activate, reprogram or factory reset. On a top dialer hold telephone line busy and on telephone i hear few people speak chines language and laughing.Chines junk.

not recommended. audio is TERRIBLE.
