HSI Sensing (HSI), an Oklahoma-based manufacturer of custom reed switch and sensor technology, announced at Global Security Exchange (GSX) that its high-security sensors product line – Sentinel – now includes retrofit models. Sentinel Retro is compliant with existing models on the market to facilitate the ease of replacing outdated sensor technology with the newest innovations from HSI.  “Our company is innovative, solutions-centered and responsive, so when we heard of clients struggling with upgrading their sensor systems, we knew we immediately needed to create the Retro Model,” said Ryan Posey, CEO of HSI Sensing. “Utilizing Sentinel’s tried and true technology, the Retro Model makes it easier than ever for clients to achieve top-of-line security with a simple swap of sensors in an existing location. Designed For Anti-Tamper Features HSI launched its Sentinel sensors line in 2017 as an enhanced technology for high-security intrusion detection. Sentinel sensors utilize Solid State technology and are designed with a wide range of anti-tamper features allowing them to resist physical, electrical and magnetic tampering. It is intended to be a door contact sensor and entry-point alarm where failure is not an option, like at government facilities, prisons, banks, power plants, weapon sites and other high-security areas. The Sentinel Retro sensor also comes in a dual alarm version and a dry circuit version The Sentinel Retro models feature the same screw hole patterns as other high-security sensors currently in the field, allowing the models to be drop in replacements for existing uses. The Retro Models, just like the rest of the Sentinel line, have received the highest high-security standard listing available - a UL 634 Level 2 listing. Achieving this puts the products in an elite tier and requires 16 additional standards to be met beyond the initial 40 for a UL 634 listing. Dual Alarm And Dry Circuit Version To further extend the Retro Model uses, the sensor also comes in a dual alarm version and a dry circuit version. The Sentinel SM2 Retro Dual Alarm is designed with two alarm outputs, making it the ideal choice when a secondary circuit is needed for an indication light, access control system or other addition. The Sentinel SM2 Retro Dry Circuit is designed to convert the alarm and tamper outputs from a digital signal to a dry contact signal, internally changing the two-wire output signal to a set of SPDT switches. These also have a UL 634 Level 2 listing for exceptional security performance.

HSI Sensing, an Oklahoma-based manufacturer of custom reed switch and sensor technology, announced at ISC WEST 2018 that its high-security sensors product line – Sentinel – now includes four new UL 634 certified sensors. HSI launched its Sentinel sensors line in 2017 as an enhanced technology for high-security intrusion detection.    “We are excited to offer an expanded line of Sentinel products to our customers,” said Ryan Posey, CEO of HSI Sensing. “Sentinel is tried and true as a leader in high-security uses, but we pride ourselves on constant innovation to meet our clients’ ever-changing needs. We look forward to continuing to grow this line and providing exceptional solutions and service to clients.” Two of the new models - recessed & retro – carry the UL 634 Level 2 High Security certification Anti-Tampering Features          HSI’s Sentinel sensors utilize Solid State technology and are designed with a wide range of anti-tamper features that allow them to resist physical, electrical and magnetic tampering. Sentinel is intended to be a door contact sensor and entry-point alarm where failure is not an option, like at government facilities, prisons, banks, weapon sites and other high-security areas. The Sentinel product line received a substantial expansion for ISC West 2018 with the addition of the four new UL 634 certified products. Two of the new models - recessed & retro – also carry the UL 634 Level 2 High Security certification. The new products build upon the market-leading technology HSI introduced in 2017 with the original Sentinel surface mount. Sensors For Residential And Commercial Security The recessed version is a concealed mount for use inside door frames, and the retro version is compliant with existing models on the market to facilitate the ease of replacing outdated technology with the newest innovations. The other two new sensors are SRC+ products and are door and window contacts for the high-end residential and commercial markets – they feature much greater resistance than standard market products currently available. The expanded Sentinel high security sensors line is certified and available for delivery now. HSI is also working on several other developments, which will be released in the coming months.

HSI Sensing is one of the five companies worldwide to achieve UL 634 Level 2 listing HSI Sensing, an Oklahoma-based manufacturer of custom reed switch and sensor technology, announced its Sentinel high-security entry-point sensor has been UL 634 Level 2 listed, placing it among an elite group of security sensors capable of monitoring highly sensitive areas. HSI Sensing is one of only five companies worldwide to achieve the UL 634 Level 2 listing.“We are very excited to announce the availability of Sentinel,” said Ryan Posey, CEO of HSI Sensing. “By using Hall effect technology, we were able to develop a new and unique product that meets all the needs of the high-security industry. Sentinel is an innovative product intended to be a door contact or entry point sensor useful in a wide range of security applications, for monitoring everything from bank safes to doors in government facilities.”Sentinel Entry-Point Sensor “We are very excited to announce the availability of Sentinel” Sentinel is designed with a wide range of anti-tamper features that allow it to resist physical, electrical and magnetic tampering, all in a package 50 percent smaller than comparable sensors, while still offering adaptive digital processing. At the core of Sentinel, multiple Hall sensors detect the actuator’s magnetic field in the x, y and z axis. Most security sensors only detect the presence of a magnetic field. Sentinel can detect small changes in the magnetic field caused by other magnets or movement from the actuator. This technology makes Sentinel ideal for monitoring highly-sensitive areas, including Sensitive Compartmented Information Facility (SCIF), financial institutions, data centers, military facilities, prisons, power grid facilities, airports, seaports, and other high-level secure applications.UL 634 StandardUL, an independent safety science company, introduced its UL 634 as the standard for all connectors and switches for use in burglar-alarm systems. It is the standard for SCIF intrusion detection systems for the government intelligence community, which has a preference for Level 2 devices. The UL 634 requires 40 standards be met to be listed, an additional eight testing criteria to achieve Level 1 and another eight requirements to achieve UL 634 Level 2. These eight requirements for Level 2 include passing a switch assembly removal test, a magnetic field compromise test, and an extended endurance test.Sentinel is offered in two variations, with a rear-exit cable and side-exit, metal jacketed cable. Every Sentinel sensor includes a recessed tamper plate, actuator, mounting hardware, and security screws. It’s aluminum housing can be anodized in a limited number of colors to help match the entry point it is monitoring.
