The effective lifespan of perimeter detection alarms varies based on the type of system and its components. summary of the lifespan for different types of perimeter intrusion detection systems (PIDS):
Lifespan of Perimeter Detection Systems
Taut-Wire Systems (e.g., DTR by Magal Solutions):
Lifespan: Over 30 years.
Features: Designed to withstand extreme weather conditions, including high winds and snowstorms, with low false alarm rates and high probability of detection.
Fence-Mounted Sensors (e.g., SL-3 Vibration Sensor):
Lifespan: Approximately 20 years.
Warranty: 10-year warranty on the sensor cable, highlighting durability and maintenance-free operation .
Microphonic Cable Systems:
Lifespan: Typically around 5 to 7 years.
Considerations: These systems may incur higher annual maintenance costs and are susceptible to environmental factors that can affect their reliability.
Fiber Optic-Based PIDS:
Lifespan: Generally designed for long-term use, but specific lifespan details can vary based on installation and environmental conditions.
Advantages: Immune to cable severing and can provide accurate intrusion reporting .
General Motion Sensors and Alarm Systems
Lifespan can vary widely; many components like controllers can last over 20 years, while specific sensors may need replacement sooner due to wear or technological upgrades
.
Summary Table of Lifespans
