这里普遍的 解释都是电池没电了, 换 电池。 我也曾经以为是这样的。。 但是 今天 刚好看见了我的一个 smoke co detector 的说明书 是 kidde / nighthawk/ firex 牌的, hardwire的。 带备用电池。 上面这么说的 after 10 years of cumulative power up , this unit will chrip every 30 seconds. This is an "operational end of life" feature will indecate that it is time to replace the alarm 所以 它过了10年会自动 响哦,说是寿命到了, 和有没有电池没直接关系。 你如果 要继续用它, 你把电断了, 电池拔了, 一会 再装上 说不定 它就不响了。

just a little bit IRE and PRGN. the market is still at a "high" position in my opinion. Not a time that I will aggressively buy buy buy.
