INTRODUCTION 
This product is a part of the 
Marmitek ProGuard800 series, 
and operates together with the 
ProGuard800 alarm system. 
When you wish to know more 
about the complete system, its 
possibilities and its settings, then 
you can check out the 
installation manual or visit 
www.marmitek.com. 
All of these sensors implement a 
feature to combat the problem of 
multiple transmissions, which 
drastically reduce the life of the 
batteries. After each transmission, 
there is a four-minute delay during 
which further transmissions will not 
be sent. 
The MS845 are designed for 
installations prone to nuisance 
alarms caused by pets or small animals.
