Intro

The TOC-750 Safe Area addressable gas detector from International Gas Detectors has become the industry standard for the detection of flammable, toxic and asphyxiant gas hazards. Our range of long-life Plug-and-Play sensor options enables the accurate, effective monitoring of over 700 distinct gas threats.

Design

The design is lightweight, ergonomic and robust and features DIN-rail mounting options, ensuring that the TOC-750 Safe Area can easily slot into your gas detection setup. The moulded detector front features a unique labyrinth sensor design intended to protect the sensor from dirt, gas migration and ingress and ensure a longer operational life.

Multiple I/O Points per Detector

The TOC-750 Safe Area detectors include numerous output and input options, meaning that a single detector can interact wiht beacon sounders, solenoid valves, emergency stop buttons and up to 7 accessories, eliminating the need to wire every element of your gas detection system back to a controller. This further reduces cabling and installation requirements, offering distributed control without the necessity for costly I/O cards.

Replaceable Sensor Fronts & Auto Changeover
The 750 Safe Area gas detector features Plug-and-Play, replaceable sensor fronts. When a sensor reaches end of life, simply swap the front with another pre-calibrated unit, reducing maintenance costs. Auto-recognition features will automatically switch to the new target gas if necessary.

Sentinel+^TM - Swift, Simple, Safe.

Sentinel+^TM is IGD's exclusive gas detection system. The concept is simple: Power and communications are both handled by a single 2-core cable, slashing both installation costs and time. This is made possible by our Sentinel+^TM software, a communication protocol specifically designed and optimised for gas detection. Sentinel+^TM is the future of gas detection- Now.

• Polarity-independent 2-core cables eliminate the potential for human error and massively reduce installation time.
• Advanced digital data allows you to delve into sensor diagnostics and gain detailed insights into faults, alarms and the status of your entire system.
• Link detectors and accessories in series to the nearest controller. Less wiring means less money and better reliability.
• GasNet remote monitoring functionality means you can receive SMS & email alerts, and address your whole system from anywhere via a mobile phone, tablet or laptop.
• Save more by repurposing your existing wiring.
• Integrate our products into existing 3rd-party digital and analogue systems via BACnet, Modbus or relays.
