Cisco ® Unified Communications Solutions enable collaboration so that organizations can quickly adapt to market changes while increasing productivity, improving competitive advantage through speed and innovation, and delivering a rich-media experience across any workspace, securely and with optimal quality.
The power of the Cisco Unified Communications Family of products extends throughout the enterprise, delivering a powerful, converged wireless solution with intelligent wireless infrastructure and an innovative new product: the new Cisco Unified Wireless IP Phone 7925G-EX (Figure 1). This device is certified for potentially explosive environments in the gas, oil, and chemical production fields as well as dust-filled environments.
ATEX and CSA Approved
The Cisco Unified Wireless IP Phone 7925-EX is ATEX Zone 2 certified. Zone 2 is defined as an area in which an explosive gas atmosphere is not likely to occur in normal operation and if it does occur, is likely to do so only infrequently and will exist for a short period only (for example, less than 10 hours per year).
The phone is also CSA Class 1 Division II certified. Class 1 is a location where a quantity of flammable gas or vapor sufficient to produce an explosive or ignitable mixture may be present in the air. Division II is a location where a classified hazard does not normally exist but is possible under abnormal conditions.
Features
The Cisco Unified Wireless IP Phone 7925G-EX delivers all the capabilities of the Cisco Unified Wireless IP Phone 7925G with the ruggedness and resiliency that is certified for deployment in environments such as chemical and manufacturing plants, utilities, and oil refineries.
Features include:
- Atmospheres Explosibles (ATEX) Zone 2/Class 22 certification prevents ignition of surrounding gas vapors by the phone.
- Canadian Standards Association (CSA) Division 2/Class 1 certification provides access to mobile collaborative communications.
- IP64 rating for superior and splashing water resistance adds resiliency.
- Industry-standard yellow styling offers fast recognition if an emergency occurs.
- The phone meets 802.11a/b/g standards for voice over WLAN (VoWLAN) communications support.
- The phone supports third-party Bluetooth 2.0 headsets for added freedom.
- The large 2-inch color (176 x 220 pixels) display makes viewing easy.
- The phone offers exceptional voice quality with High-definition (HD) voice.
- A built-in full-duplex speakerphone offers high-quality hands-free communications.
- The Applications key provides direct access to XML applications such as push-to-talk and Lone Worker.
- Extended-life batteries deliver a minimum of 13 hours talk time and up to 240 hours of standby time.
