  • can be connected to valve or alarm system

    posted by EugeneM

    can be connected to valve or alarm system. Plastic case has hole for cable. Valve or alarm system cable can be soldered. Relay can be installed onto PCB to have dry contact output. Alarm sound is strong enough.
    It's not easy to check sensor with natural gas. Sensor can be checked with butane from gas lighter.
  • Great Wireless Ir Detector!

    posted by Gringotson

    Its got a red led witch blinks when the Ir detector is activated and when it "senses" movement so its easy to install, it also comes with some jumpers to change the frequency code to set it up on the alarm system, it has good wireless range and has an extendable antenna.
    No other thoughts.
    If you want to expand your covering range in many different rooms of your house then these are a good and cheap way to do it, they have exellent range, extendable antenna and great coverage, jumper setting for different frequency codes.
  • Barato y efectivo. muchas posibilidades

    posted by SrDonGato

    tiene muchas posibilidades de configuracion, puedes activar y desactivarla desde los 4 mandos SMS o por telefono. llama hasta 5 numeros de telefono de forma ciclica, sensores efectivos aunque aun no se que autonomia efectiva tiene cada uno. centralida MUY configurable e instrucciones en ingles pero muy intuitivo.
    muy barata para las funciones que tiene. en dx.com se consiguen mas volumetricos por unos 10 dolares
    la alarma esta instalada ahce un mes y no ha tenido ningun problema de funcionamiento.
  • Don't know if it's working

    posted by Sullivan

    very cheap device, easy to use, great for installing in every room. Runs on a 9V battery (included it the package), has a led to indicate its working and if the battery is low.
    Is there other way to check if it's working? I don't really know... Not sure I can trust it to save my life in a case of fire.
    It looks like a smoke detector, but I'm not sure it's doing the job.
