Kidde smoke alarm need to be replaced

By Jim Sheng
We do a lot of cooking, mostly stir-frying, the extractor fan has been broken since we moved in, so our kitchen alway very smoky, we got a new extractor fan installed recently, though.  The smoke triggers the fire alarm in the hallway. I normally don't bother to hush it, open the doors and windows instead. This fire alarm might be working too hard, it started chirping early yesterday morning, I tried the Hush button, it stopped chirping. Then started again yesterday afternoon, this time, pressing Hush button has no effect. Then we left it alone and went to shopping. When we came back, the annoying chirping has stopped. But it started again last night and woke me up, so I removed it to the garden shed. According to the instruction, "an intermittent chirp (every 45 seconds) indicates the alarm has reached the end of life and must be replace." The alarm makes a lot of noise when it's dying.

I checked the back of the alarm, there are short instruction on it. it 's Kidde's sealed, battery powered smoke alarm with hush. The lifespan of Kidde Wireless products is 10 years, so it must be replaced within 10 years.

Temporal (three pulse) alarm idicates particales of combustion have been detected. Flashing of the red LED every 45 seconds indicates the alarm is operating. Rapid flashing of the LED when the test button is pushed indicates alarm memory (The alrm has sounded since it was last tested). An intermittent chirp (every 45 seconds) indicates the alarm has reached the end of life and must be replace.

The hush button will silence the alarm for 8 minutes (dense smoke will override the Hush), during this time the red LED will flash every 10 seconds. Not recommended for operation below 40oF or above 100oF or in humidity greater than 85%. Clean your alarm annually using compressed air or a vacuum cleaner hose around the perimeter of the alarm. If cleaning does not restore the alarm to normal operation, the alarm must be replace.

The battery-powered alarms can be installed in any room in a matter of minutes – no wiring required. You simply screw the mounting bracket into the ceiling just as you would a traditional smoke alarm.

I wonder where can buy it, Homebase?

coat-of-arms

By Jim Sheng
Heraldry probably began with the knights in armour. When wearing a helmet in battle or in tournaments a knight could not be recognised; so he used symbols to decorate his shield and surcoat. The surcoat was the loose garment worn over the armour to protect it from rain or hot sun and actually was the "coat-of-arms"; it was decorated on the front and back with the same device as on the shield. The correct expression for entire design is an achievement . An achievement consists of the shield, helmet, rest, wreath, mantling and motto. These are the main parts. To them can be added supporters and a compartment. In the centre is the most important part, the shield . The surface of the shield is called the field  and on it the colourful charges are placed. The shield is called the arms or coat-of-arms  and can be drawn in any shape - in an upright position or slanting, which is the position it would fall into if hung on a peg. In Heraldry it slants to dexter. The helmet denot...

You can find your Wireless Network Key on Virgin Media Wireless Router

By Jim Sheng
We have a new netbook computer, and don't know where to find network key, which is needed to setup wireless connection. A network key may also be called WEP (Wired Equivalent Privacy) key or WPA (Wi-Fi Protected Access) key. A wireless network key is a security feature that prevents unauthorized users from accessing a wireless network. An unprotected network is an unlocked virtual door, anybody within range can piggyback on the network undetected. I use Virgin media broadband with a Virgin media wireless router, this router has a WPA key taped on the router, that WPA key is an English word consisting of 10 letters. To tape network key on the router is a good idea, because we may never lose or forget a wireless network key as long as we possess the router.

The Meaning of Derby City Council Logo

By Jim Sheng
Derby City Logo The logo of Derby City Council looks quite abstract and modern. I wonder what's the meaning of it? The lower-left part of the logo looks like a snail (or the initial letter D in Derby?), the upper-right part seems a river, (Derwent river?) these two parts are connected by a straight line at the bottom. I did some searches on the web trying to find out the true meaning of Derby City Council logo, but without success. So, I wrote to tourist information, and got the answer from Michael: The Logo is a representation of two of Derby's oldest emblems, one being a ram the other a buck (deer). Obviously the logo is a modern interpretation of these two figures so it is not obvious unless you know what to look for. Most people do seem to agree with you that it looks like a snail however. Ram! the curly horn of ram looks like a snail indeed. The ram and the deer are from coat of arms of City of Derby, In this coats of arms, we can see the deers both in shield (arm...
