Description
"The Next Generation Military Grade High Security Intrusion Sensor"; a novel 3D Balanced High Security Magnetometer System (3D-BMS). This revolutionary new generation of BMS replacement is the only known intelligent 3D Magnetometer Security integrated device (also called Smart Magnetometer or digital Magnetometer). It is the only High Security Switch (BMS / HSS) in the world that cannot be defeated by "Trivial Means". It is also the only BMS technology in the world that can be networked and interrogated.
The JRM1212L 3D-BMS / HSS meets or exceeds US Federal Specification Components for Interior Alarm Systems, Balanced Magnetic Switches W-A-450/1 August 28, 1990 in addition to UL Class 94V-O and UL 634 Class 2. Our 3D-Balanced Magnetometer Switches (3D-BMS) / High Security Switches (HSS) is a completely new technology that maintains backwards compatibility with existing legacy installations.
General
The JRM1212L High Security magnetometer features a legacy interface to existing systems. It is designed to operate from the standard 12Vdc security network power lines. The sensor output is open collector for voltage level translation. The output is pulled low in a secure state. The alarm state occurs by default if power is removed from the device in an active security system. Remote test is automatically conducted when power is applied to the device and may be conducted at any time by placing a 12V pulse on the remote test line.
Functional Gap
The optimal sensor actuator mounting gap is 0.175 inches. The minimum sensor actuator mounting gap of 0.00 inches. The device may become
susceptible to defeat, if operated outside recommended parameters.
Thermal Extreme Alarm
The device temperature is continuously monitored and generates an alarm when the ambient temperature exceeds 70°C or falls below -20°C. |
Mounting Surface
The magnetometer and actuator can be mounted directly on any non ferrous surface. The device must be mounted at least 1/4 inch from any ferrous surface. Special spacers are supplied for this purpose which also includes the anti-tamper feature: the switch will not work without it. Some ferrous objects in the vicinity of the magnetometer or actuator may trigger an alarm.
Extraneous Field Susceptibility
The device is insensitive to high frequency magnetic fields such as those generated by transformers and electric motors. Low frequency magnetic fields, such as those generated by permanent magnets in the vicinity of the device are interpreted as an attempt to breach the security system and generate an alarm state. All inputs and outputs have Class A EMI suppression filters which also provided a measure of protection against lightning. This intelligent device can detect extraneous magnetic fields introduced to mimic the actuator including but not limited to sliding permanent magnets into the gap between the sensor array and the actuator.
Remote Test
A 12V pulse on the Remote Test line (purple) resets the device, sets a “Secure State” for one second, sets an “Alarm State” for one second and then returns to active sensing.
False Alarm Immunity
Shock, vibration, and induced line voltage transients are the primary cause of false alarm indication associated with magnetic contacts. There are no electrical contacts to fail. EMI filters eliminate false logic states under normal operating conditions. Consequently, these environmental false alarms have been eliminated. |
