Hard-Wired Touch Screen Driven System In The Uk

[ChrisMurphy]

just to add a little.

 

one issue with diy even if you do it better than a pro (somehow), is that a blank external unit advertises the fact that you do not have an alarm installed by a company they know (and fear their systems).

 

As for dogs often an issue is that the routine of walking them can be used against you.

sources in the UK that sell the DSC kit too,

Forget dsc, it will bite you in the ass one day..

Jonathan, take a look at the Galaxy Dimension range. If you can source their RSS software, then you could write some database wrapper app to send SMS to yourself, or even self monitor remotely with heartbeat detection via low cost provider

 

You can also run the virtual keypad remotely or via WiFi on your tablet.  The Honeywell virtual keypad is slightly more secure than some of the others which use no passwords or 4 digit access codes. The G2 panels have 100M passcode combinations and the Dimension/Flex being alphanumeric is much more.

 

Also, I have a few customers who have battery backed GSM failover (Using Draytek dual WAN) on their network, thus ensuring continuation of the network if line cut or power failure.

i suggest have a look at Risco Lightsys, has option of touch screen and small normal keypads, supports various communication, methods, including signal cloud the to where ever you want. Smartphone remote operation of alarm and outputs modules which means you can turn the heating on before you leave the office as example.

Perimiter protection that allows you ti move about will be more costly than 'trap' protection, where intruder enters and eventually walks through an armed motion sensor, tbh it would be cheaper with so many detectors needed to go wireless, then you could have detectors that take snaps, sent to cloud then to your phone Risco Agility offers this, but not a touch screen option. Tbh you could do all you need from your tablet or smart phone.

End of the day, no matter what you spend it's net result is to sound a siren, even Police connected via a monitoring station is no added guarantee the intruder will be caught in time before they attend. The camera option is getting very popular for that reason.

CAT5e is perfectly fine, but not much liked by alarm engineers due to cracking at termination if not stripped carefully, it can snag in the terminals damaging them, also if bent in half to thicken makes an effective fishing hook into fingers.

Peter is partly right that CAT5e it is twisted pair, designed for stricter data transfer characteristics, but that only affects on data. as long as of a good quality, CAT5e resistance is so low as not to be negligible for the alarm circuits. Today cable comes as CCA (Copper Clad Aluminium). Avoid, basically aluminium painted with a copper, while cost is much cheaper it is like working with fuse wire, be easier to circumcise an ant than to strip it without damage, even the multi-stranded version

to make the point, If you allow 50 ohms in a 100 meters (and thats a very long run), it will have no effect on zones using 1k upwards DOEL resistors, and it will likely be far better than alarm cable between panel and zone expanders (because they use data), over long runs at resisting RFi. due to it's strict impedance value.

Old BS.4737 insisted on alarm stranded cable, where as latest EN standards simply state 'using cable suitable for', so even they agree with me for a change lol!
