Wireless Alarm System

I have a wireless alarm system Arlec but have lost the instruction manual. Does anyone know how to install? Thank you

You do not say you have a model system, but if you go to the Products page to Arlec http://www.arlec.com.au/products.php?pid ... then select AM or DA series await links to be presented with a list of different models. At the bottom of each description of the system is a link to a PDF of the manual system. If your system is not listed, you can go to the Contact Us web page and call on your system.
