Introduction Contents
Thank you for choosing the Yale Wireless Alarm System. 
This simple to install system has been designed with the 
user in mind. 
All the components are self contained and no connections 
are needed between the units. There is no need to 
damage the home decor, lift carpets or run cables. 
You can install up to 20 devices in this system. As well as 
extra door/window contacts, PIRs and smoke detectors, 
you can add keyfob remote controls and keypads for 
added control convenience.
There is no need to wire into the mains supply or seek 
the services of a qualified electrician. All components are 
powered by battery (all batteries included).
Batteries will operate for 2 years or more before they need 
changing. Regular testing and battery changes (when 
notified by the system) will ensure reliability and peace of 
mind. 
Each part of the system is ‘tamper’ protected. Any 
unauthorised tampering with the system will result in an 
alarm. This feature can be turned off by the user when a 
battery change is required. 
The system has a fixed 20 second entry/exit time when 
use with a Keypad. This feature allows you time to leave 
the home when arming the system. Upon entering, the 
feature allows time to disarm the system without causing 
an alarm. Please note there are no countdown when using 
a Keyfob to arm or disarm. When the siren is triggered, it 
will sounds for 10 minutes. 
Display extreme caution when using ladders or steps, 
please follow manufacturer instructions. Be careful when 
using hand and power tools and follow the manufacturers’ 
guidelines when using them. Take care that the correct 
tools are used. Wear goggles or protective clothing where 
required. 
The external Siren is extremely loud, please ensure you 
replace the cover and retreat to a safe distance before 
testing.
