Many communities are now required to install the adapter, installing a adapter not only can improve the safety measures in the home, at the same time the whole community security has improved a lot, sometimes the head of the community the door to check. Make sure that the security of adapter is being used, and it will be checked regularly. I think the community leaders are quite serious about their work and do a relatively good job. Despite this, but also became a habit, is back to check every once in a while, see if the adapter in the home is a fault, god to remove some than necessary problem, every time do the inspection work of careful, every detail to check special fine!
