If you check the manual there is a jumper you can switch in the siren so that stray wireless signals will not cause the anti jamming circuit to set off the alarm.

EDIT Is not anti jamming, it is only jamming detection, an effective anti jamming function would require a change of radio frequency to use a clear un-jammed frequency

To disable the anti jamming circuit is the same as disabling the tamper circuit in the siren of a wired alarm system.

In a wireless system the siren has to have clear and reliable communication with the control panel in order that the control panel can command the siren to sound. If the communication channel is not clear and reliable then the control panel may not be able command the siren to alarm when an intrusion is detected.

In a wired system the comunication is by wires. If these are cut then the alarm will sound. In some wireless systems it is possible to "cut" the communications between control panel and siren by jamming the radio channel. When this happen it has to be bought to the attention of the user / owner of the property as the alarm is now not able to sound the alarm if an instrusion occurs.

If the wireless communication to the siren is being jammed then the communication from sensors to panel is also likely to be jammed and in some non compelled systems this will render the sensor in-effective.

Where the control panel function is part of the siren then the jamming detection function is essential.

( Compelled systems use two way communication between panel and sensors and if a sensor fails to reply to the sensor's requset for status then the system goes into alarm or tamper condition ).

With more and more equipment using the frequencies that many alarm systems use the incidents of jamming are going to increase.

Just goes to show what a fool you are then.
You cannot work on real alarms.
You cannot work out I am not inclined that way.

Sad, best thing you go ehh ;)
 
I`ll leave you embarrassed every time you think you know about security systems.
 
Forget security who needs it?
We can leave our wives our families and everything just you and me against the world - how romantic.. :p
 
Pathetic.
You have been proven wrong yet again and now decide as you cannot discredit me professionally with your lies, you try another tactic.

Carry on, you just look more and more idiotic.
 
You see thats where you are going wrong.
If you just left me alone to answer Yale querries without butting in and slagging off the product everything would be hunky dory and noone would get upset.
Yale consumers would get good advice and you could answer the grade 2 kit questions unmolested. But you just won't let it lie. You wont accept some people don't want pro kit and just want a simpler cheaper alternative.

You should go to an estate in Leeds where I have fitted many many alarms. Yale alarms outnumber professionally fitted ones at a ratio of two to one. If they were crap the word would soon get round and noone would ask for them but I am still fitting them there now just as I was three years ago.
In fact just installed one for someone who has just moved there and I installed one previously at their last house two years ago.
 
Awww your upset.
See a doctor.

As for Leeds, I have several systems up there. As well as access control, the prime mover there is cost and the need for cheapness. Hence I cannot be bothered there anymore.
The customers there are old friends and multinational. Otherwise its not worth it there.
 
Yep, cheap DIY stuff. Which someone mugs them off for fitting, when it is ready to go out of the box. Plugs into a standard socket.

WOW

Which estate? I'll go on Alarms behalf
