Hope someone can help.....
We have a Friedland SA5 6 zone wireless alarm system that I installed approx  
five years ago, and have maintained since. This unit is very similar to Yale  
wireless alarms so one or othe is probably a rebadged version.
Anyway we've recently changed house building & contents insurer. Our new  
insurer is insisting that there is a maintenance contract in place. I've  
been phoning round & consistently failing to find a company who will take on  
a diy installed system.

Are there security companies out there who will maintain diy installed  
alarms? or will I have to give up & get an equivalent approved system  
installed at vast unnecessary expense.
Location is Ealing, West London.  



Re: House insurance and burglar alarms
Having read the thread I would like to add the following for the groups  
discussion.
I agree with all who say change your insurance carrier as the discount is  
far less the cost of an alarm contract.
However an alarm in a domestic property can be justified if it gives piece  
of mind to the occupier and alerts neighbours to an alarm or frightens off  
the robbers.
An alarm will never stop you being robbed if the thief want to take your  
things they will find a way.
On a technical front, PIR detectors can last over 15yrs but deteriorate with  
age becoming hyper-sensitive causing false alarms.
Dual tec devices start to fail mainly because the microwave antenna corrodes  
(especially in damp or cold locations like garages) this causes the device  
to go out of tune giving false alarms.
Modern analytical vibration sensors (if setup correctly) will detect forced  
entry on uPVC windows before the glass is broken. Mine did and still do.
The Redcare system is a BT dedicated telephone line which is monitored 24/7  
so the monitoring station will know if the line is cut before you do.
Modern dual-com monitoring systems use both the mobile phone network and  
landline together so unless you jam the mobile signal and cut the phone line  
at the same time a line fault will be sent to the monitoring station.
By law external bells must stop after a predetermined time (usually 20mins)  
but this is set by local authorities.This said if the alarm is programmed to  
auto reset as most are the bell will stop for 10secs then start again.
Monitoring stations will call the police but most forces and stations  
operate a 3 strikes and you're out system.
ie. Within a set timeframe ;1st false call a warning 2nd a fine ,3rd a  
bigger fine and no more monitoring (NB you will still have to pay for the  
duration of the contract.)
From the above it becomes clear that to guarantee everything works a company  
must regularly check the system and would not normally take on a DIY  
install.
We all know this is not always the case but hopefully you can see why nobody  
will touch a DIY system.

I have tried a number of them...

Focus Dual-tec: 7 out of 8 failed within 3 months and returned.
     The one remaining one is still working fine 12 years later.

Pyronix Equinox Dual-tec: No failures in 12 years, but have had
     to increase sensitivity on one in a cold location.

Guardall Astra Micra dual-tec: No failures in 12 years.

Pyronix Octopus 360 degree PIR-only: They all lasted about 5 years
     before starting to generate false alarms.

Scantronic 460 dual-tec: too soon to say, but no problems in 6 months.

AEI 360 degree PIR-only (CPC): too soon to say, but no problems in 6 months.

or even a system installed by another alarm company, unless they're
doing a bulk take-over of all their business.
