i.safe MOBILE IS Accessories

IECEx-approved Ex-Zone 1/21 Accessories

Enhancing productivity and worker safety in hazardous environments.

The i.safe MOBILE range of IS accessories are designed to keep productivity and efficiency a focus with seamless connectivity, while still protecting the well-being of staff in hazardous environments with IECEx-approved accessories.

The IS-TH2ER.1 Trigger Handle (Hand-held Barcode Scanner), when used with the i.safe MOBILE IS540.1 Smartphone Zone 1/21, enables fast, accurate data acquisition in IECEx Zone 1/21 areas.

Ideal for applications in high-bay warehouses and large production areas. PRZM Intelligent Imaging technology and the green aimer, optimises barcode scanning even in difficult environment. The data is further processed directly via the i.safe MOBILE IS540.1 Smartphone Zone 1/21 connected via the ISM interface.

The IS-SW1.1 Smartwatch is specifically designed for industrial purposes in IECEx zones 1/21. Coupled with i.safe MOBILE devices, the IS-SW1.1 Smartwatch functions as a supplementary “hands-free” display and can record and display critical messages, hazard alarms and measured values.

In addition, the IS-SW1.1 can be used for GPS tracking, fencing, time recording/access control, and enabling emergency calls. These features all contribute to enhanced worker safety, ensuring immediate awareness and response in the field.

Note: In order to be able to use all functions of the IS-SW1.1, additional customer-specific applications from third-party suppliers are required. These are not provided by i.safe MOBILE.

The IS-RSM3x.1 Remote Speaker Microphone (RSM) delivers clear, hands-free communication in noisy or hazardous conditions—thanks to the loudspeaker and microphones—with a rugged, intrinsically safe IECEx Ex-Zone 1/21 approved design that ensures reliable performance in demanding environments.

This RSM is either wired (IS-RSM3A.1) or Bluetooth® (IS-RSM3B.1):

• The IS-RSM3A.1 wired RSM is the ideal addition to PoC and lone worker protection applications for Zone 1/21. The lightweight device has an ergonomic design and is easy to operate even when wearing gloves.
• The IS-RSM3B.1 Bluetooth® RSM is ideal for high-mobility roles were the user needs more freedom to move, or where more discretion is required.
