- Pet immune for small animals
- Dimensions: 110 x 60 x 45mm
The detector is designed for installations prone to nuisance alarms caused by pets or small animals and implements a feature to combat the problem of multiple transmissions, which drastically reduce the life of the batteries. After a transmission is made, the MS845 initiates a fourminute delay during which transmissions will not be sent.
Pet Immunity Guidelines
It is expected that the MS845 will eliminate false alarms caused by:
- Animals up to 45kg/100 lb. (PI) *
- Several small rodents
- Random flying birds.
* The weight of the animal should only be used as a guide, other factors such as the length and color of fur also affect the level of immunity.
For maximum pet immunity the following guidelines are recommended:
- Mount the center of the unit at a height of 2 m with the PCB vertical setting at -4.
- Set the pulse counter to 2.
- Do not aim the detector at stairways that can be climbed by an animal.
- Avoid a location where an animal can come within 1.8m of the detector by climbing on furniture, boxes or other objects.
