DO NOT BUY THIS ITEM. It would be better to get robbed from a thief than pay for such crap
CAVEAT EMPTOR [Let the buyer beware.]
Light in the box seems like a good and fair place to buy.
They should buy more carefully. DO NOT BUY THIS ITEM. It would be better to get robbed from a thief than pay for such crap

Didnt know we had to set the code of the sensor manually inside the sensor.
Manual how to do this would be nice. Eventually i found out how to do it while searching on the net. For you convenience hereby a photo and text how to do it. Best wishes, Arie van Wingerden / iWing Didnt know we had to set the code of the sensor manually inside the sensor.

Great product, excellent value for money. It is an accessory of the alarm control units. Excellent sensitivity, it works perfectly even on overhead windows without ever giving false alarms. It is applied in a second through biadhesive. The batteries have a reasonable life. To connect it to the control unit, the pins of a circuit must be connected in a manner consistent with the control unit. The simplest method is to take another sensor supplied with the control unit and make the same connections. Its a very simple job that takes a few minutes.
Ottimo prodotto, ottimo rapporto qualità prezzo. E un accessorio delle centraline dallarme.
Sensibilità eccellente, funziona perfettamente anche su finestre basculanti senza mai dare falsi allarmi. Si applica in un secondo tramite biadesivo.
Le batterie hanno una durata ragionevole.
Per collegarlo alla centralina, vanno collegati i piedini di un circuito in modo coerente con la centralina.
Il metodo più semplice è prendere un altro sensore fornito assieme alla centralina e fare gli stessi collegamenti. E un lavoro molto semplice, che prende pochi minuti.

I memorized the sensor on my control unit on the first shot. I recommend it to everyone.

The jumpers are very small but workable. I installed seven of them and they are working beutifully from way back in the house. Absolutely great buy for the price. Security companies will charge you seven or eight times more for evry sensor. The instructions are a little bit fuzzy, but once you figured it out you can zone them any way you want and they work right away.

Very good product, such as excellent price quality. Too bad that with an order of 400 euros, I paid 175 customs
Prodotto molto buono, come qualità prezzo ottimo.
Peccato che con un ordine di 400euro, ho pagato 175 di dogana

I have already purchased these devices and since I was very satisfied I took others. The product is exactly as you see it in the picture; a little bit older compared to an equivalent "local" product that has the same performance. Inside you find a series of microjumper that must be set otherwise the control unit does not recognize the signal sent. You have to check the type of coding used by the other sensors you have (microjumper) and the various jumpers in order to create the desired coding. For example, I have an 8-jumper coding, so I inserted only 8 alternating the jumpers between "first and second pin" and "second and third pin" in a completely random way. The price makes it absolutely competitive to complete the wireless alarm system vs.
Ho già acquistato questi dispositivi e dato che sono rimasto ottimamente soddisfatto ne ho presi altri.
Il prodotto è esattamente come lo vedete in foto; un po grandicello rispetto ad un equivalente prodotto "locale" che ha le medesime prestazioni.
Allinterno trovate una serie di microjumper che vanno settati altrimenti la centrale non riconosce il segnale inviato.
Dovete verificare il tipo di codifica utilizzato dagli altri sensori che avete ( microjumper ) e inserite i vari ponticelli in modo da creare la codifica desiderata. Io ad esempio ho una codifica ad 8 jumper per cui ne ho inseriti solo 8 alternando i ponticelli fra "primo e secondo pin" e "secondo e terzo pin" in maniera del tutto casuale.
Il prezzo lo rende assolutamente concorrenziale per completare il vs sistema di allarme wireless.
