The installation of anti-theft alarm probes is often underestimated, with many people believing that simply mounting the devices according to the manual and adjusting their angle visually is sufficient. However, in reality, the process is far more complex and time-consuming than it appears. In this article, we'll explore some key aspects of installing these detectors that are frequently overlooked but crucial for system reliability and security.
**Pipeline Installation**
In past projects, we've seen several issues related to pipeline construction, not due to fire hazards, but due to potential man-made damage. Some installations use PVC pipes or exposed cables, which are easily accessible and can be tampered with. This poses a serious risk, as even if the system has a tamper detection feature, any damage can significantly reduce its efficiency or cause a complete shutdown. When such faults occur, engineers must spend extra time locating the problem, which can delay the system’s readiness during critical times.
Using PVC pipes for protection is not only unprofessional but also highly risky. Compared to galvanized steel pipes, PVC is much more vulnerable to physical damage. Many overseas companies, however, use metal conduits and sealed boxes for protection, ensuring long-term durability and security. This kind of attention to detail should be standard practice in all high-quality installations.
**Concealed Pipeline Layout**
During the installation of new buildings, it's essential to plan for concealed pipelines from the start. Civil contractors can embed protective pipes during concrete pouring, ensuring the entire transmission path remains hidden and secure. It's also important to pre-install small-diameter steel pipes within the conduits to make future cable threading easier.
For wiring, two cores are typically used for power supply, while the other two carry the alarm signal. However, using a six-core cable allows for an additional pair to connect the tamper switch. If this isn't implemented, a knowledgeable intruder could exploit the system during disarmed periods by removing the detector. To prevent this, the tamper wire should be connected to a 24-hour zone on the control panel, ensuring continuous monitoring.
How many projects actually follow this standard? Very few, which highlights a major gap in real-world implementation.
**Determining the Installation Location**
Choosing the right location for the detector is another aspect that is often neglected. Unlike camera placement, improper positioning can lead to false alarms or missed detections, reducing the system's effectiveness. Moving a detector after installation can be costly and complicated, requiring rerouting of cables and possibly damaging the building's structure. For example, relocating a ceiling-mounted detector from a wooden surface is nearly impossible without causing visible damage.
This emphasizes the importance of finalizing the installation location early in the design phase. A well-planned layout not only improves system performance but also avoids unnecessary disruptions later on.
**Conclusion**
The installation of anti-theft alarm detectors is a complex and often overlooked process. Its intricacies are not always recognized, especially when compared to the more visible and profitable work of CCTV installation. However, for a truly effective security system, proper planning and execution are essential. Only through careful design and attention to detail can we ensure a reliable and secure environment for our clients.
