Can RFD-12W connect directly to a security fog generator?

The recommended configuration is Jammer Detector to Alarm System or Control Module to Security Fog Generator. The alarm system should provide one-shot triggering, re-trigger lockout and reset control.

What happens if the RFD-12W jamming signal remains present?

The standard sequence verifies the signal for approximately three seconds and activates the relay for approximately five seconds. If the jamming signal remains present, the sequence may repeat.

Are economical jammer detectors suitable for factories?

They are mainly intended for simple residential, vehicle and commercial environments and are not primarily designed for equipment-dense factories with complex industrial electromagnetic interference.

Should the jammer detector be tested at the installation site?

Yes. The detector should be tested in the actual installation environment before its relay is permanently connected to an alarm system or security fog generator.

ANTI-JAMMING SECURITY GUIDE

How to Protect Security Systems from Wi-Fi, Cell Phone and GPS Jamming

Wireless alarm systems, Wi-Fi surveillance cameras and GPS tracking devices may lose communication when criminals use signal jammers. An anti-jamming detector adds an independent warning layer by detecting a jamming attempt and sending an alert to an alarm system or local command center.

Why Is a Jammer Detector Needed?

A conventional alarm system can detect an opened door, broken window or unauthorized movement. However, it may not warn the user that someone is intentionally trying to block its wireless communication.

The RFD-12W and RFD-12S are economical fixed-type jammer detectors designed to provide an additional anti-jamming warning for suitable security applications. They can be integrated into an existing security package as an anti-jamming protection add-on.

Recommended Security System Integration

The jammer detector should normally provide an alarm signal to the existing security system. The alarm panel or control module should then decide whether to activate a siren, notification system, command center.

Installation notice: CIU supplies the jammer detector. Wiring and security system integration should be completed by a security system technician or an electronics/low-voltage technician experienced in alarm integration.

Frequently Asked Questions

1. Will normal mobile phones, Wi-Fi or Bluetooth cause false alarms?

Under normal residential and commercial conditions, ordinary mobile phones, Wi-Fi, Bluetooth and similar everyday signals should not normally activate the detector.

2. Can a very strong RF signal affect the detector?

A high-output RF transmitter placed very close to the detector may cause a false alarm, reduce the jammer detection distance or create unstable operation. Examples may include powerful RF repeaters, base-station antennas beside the detector.

3. What happens if the jamming signal remains present?

In the standard RFD-12W operation, the signal is verified for approximately three seconds and the relay is then activated for approximately five seconds. If the jamming signal remains present, the alarm sequence may repeat.

4. Are these detectors suitable for factories?

These economical models are mainly intended for simple residential, vehicle and commercial security environments. They are not primarily designed for equipment-dense factories containing welding machines, induction heating systems, high-voltage equipment or complex industrial electromagnetic interference.

5. Is an on-site test recommended?

Yes. Because every building, vehicle and wireless environment is different, the detector should be tested at the actual installation site before its relay is permanently connected to an alarm system .

6. Can these products be added to an existing security kit?

Yes. RFD-12W and RFD-12S can be positioned as economical anti-jamming protection add-ons for compatible alarm, CCTV, GPS tracking and command-center security solutions.
