This is actually relatively easy - many hobby shops (eg Maplin in the UK) have kits which require very little technical know-how. I guess the pre-requisites are: Understanding your perimeter - use break sensors on the highest risk areas (doors and easily accessible windows) use motion sensors in key hallways do you include your garage do you include ...

There are several online shops where you can buy anything from a basic wireless security system with peel and stick sensors all the way up to the same panels that professional installers use. If everything is already wired up as you said, then this should be a fairly straightforward DIY project. (One quick note though, even if it looks perfectly wired, you ...

If the wire for the switch and the bell that is in the existing conduit is carrying 110V, the answer is NO. You can not mix High & Low Voltage in the same conduit, so you will need to run an additional conduit to connect to the second set of terminals. Is this for your residence or for a business? I question this as you are "playing with fire", in ...

Alarm You could pick up a magnetic window/door alarm (some more expensive models may also have glass break sensors). If the window is opened, the alarm will sound. Secure the window You could purchase, or make a "security bar" similar to the ones used for sliding doors. This will make it more difficult to open the window, though would not protect ...

If it is available in the UK, I would go with Z-wave technology. While I have only dealt in the US, I hope this can help. I've sold quite a bit of Z-wave and been trained in installation it's similar to installing regular devices like switches and dimmers. Programming is simple with the remote, and I hear the computer interface makes it easier. In the ...

If the modem is the only problem, replacing it might well solve the problem. As for finding a particular model of old modem at a non-outrageous price - ebay; sometime patience is needed for a very specific model or to get it at a non-absurd price, but generally modems are pretty cheap there. Where the number is programmed - to be certain, you'd need a ...

My suggestion is that you try pressing in (or up) on these two tabs: And then that the lower part of the unit will hinge down. The hinge edge being along here:

Have a look at Iris. You can mix and match components such as door/window sensors, thermostats, motion sensors, etc. It hooks to your wifi and can send you text alerts.

Most security system have a minimum of 9v DC, but I've seen up to 60v AC or DC, running to the sensors. The concern here is voltage drop as these are extremely low current devices. If you are using magnetic/reed switches, which it sounds like you are, they are unpowered digital switches (either on or off). Digital logic circuit typically require >50% of the ...

HEMS, the vendor, answered my enquiry. There is actually a clip (first image in the original question) with an arrow mark on it. The problem is that the mark is uncoloured, very difficult to be noticed from where I stand. Push the clip to the left to release the lock, then pull down the whole thing.

The system is designed to dial out on a phone line to a central station or a police monitoring system. These alarms have built in warnings for a failure in the phone line. This is a safeguard so you know the system is not working properly. So long as the system is operational and cut off from the phone line, it will continue to beep. By removing parts of ...

Here's at least one for you: http://firstalert.com/component/flexicontent/82-explosive-gas-co/929-plug-in-combination-explosive-gas-carbon-monoxide-alarm I don't know why combination alarms are not more common. Maybe because natural gas has an odor added so it's readily apparent, unlike CO? There also aren't any dual smoke detector (ionizing and ...

One such device from Reliance Controls, is the PowerOUT!™ The PowerOUT!™ is a power failure light, power failure alarm and a portable 6-hour LED flashlight. When plugged into a standard 15A, 120V outlet, the PowerOUT!™ will sound an audible alarm and illuminate three ...

I pre-wired my house for an alarm since the alarm got fitted at the very end. I figured it would reduce the work required for the final install. I installed wires for the motion sensors, reed switches for under-house access, the control panel and the siren. From memory, some units require 6-core (such as the control panel) and some 4-core so I think I just ...

When we do drywall, if there's a loose wire (e.g. electrical line for a hard-wired dishwasher), we cut a small hole and pull it through during installation. Pretty easy to do while everything is open and you can see both sides of the drywall. Leave plenty of slack so it can be fished through the drywall before it's been attached to the wall, and the hole can ...
