Both components may be used together to form an explosion proof telephone system under Class I, II, III, Division 1 and 2 hazardous locations. The indoor telephone is configurable with master\/slave systems and rack barrier\/isolation barrier configurations. Both system components are 120V\/240V compatible (voltage selection at the bottom of the page). \nIntrinsically Safe Telephone Features: This intrinsically safe telephone supports a switchable 110VAC\/220VAC power supply and 12V nominal voltage. It can operate in temperatures ranging between -40°C and +60°C, making it suitable for subzero environments. The housing is NEMA Type 12 and is constructed of anti-corrosive, polyester material. This allows the unit to resist thermal degradation, while providing protection against chemicals, solvents and salts. The unit is fully sealed with concealed mounting accessories. Weighing just six pounds, the explosion proof communication device supports the following dimensions: 8€ x 9.5€ x 3.8€.\nThe €œG€ style handset features a noise-cancelling microphone, as well as robust volume control. A six-foot cord that is made out of Hytrel can be found on the device for extended usage. The keypad is chrome plated and supports Braille functionality. With a REN 0.4B, €œshrill-type€ penetration ringer, this unit is suitable for moderately loud work environments. This intrinsically safe telephone is registered under FCC Regulations, IC Certified and cUL\/UL Listed for use in hazardous installations.\nIsolation Barrier Features: The Isolation Barrier supports 90-132V and 180-240V @ 47-63 Hz AC power input options. While the Intrinsically Safe Interface (ISI) features a maximum voltage of eight volts, 66 ohms resistance and 136 mA current limited. The unit is compatible with 2-wire (BELL Pub.61100) and 4-wire telephone network interfaces. This component is to be installed in a non-hazardous area of the location up to one mile from the explosion proof communication device. The Isolation Barrier interior comes with a power switch selector, a ring pitch adjustment, and four troubleshooting LEDs. Externally, the component consists of two modular subassemblies, the front panel and the rear enclosure assembly, for easy installation and wiring.\nOperators may adjust the pitch of the ring between 1 kHz and 8 kHz. This device operates in temperatures ranging between -40°C and 60°C with 95 percent (non-condensing) relative humidity. The Isolation Barrier supports a glass-reinforced polyester body, which is Type 3R rated, making it highly resistant to rain, weather and chemicals. There are four indicators on the unit that notifies operators about a wiring short in the IS phone and if the TELCO line has an open. In the event of an intermittent wiring short in the IS phone, the notification lights will flash. The Isolation Barrier features twisted pair (shielded) wiring with a wiring conductor size of 24 AWG. This component€™s wiring loop resistance is 275 ohms with a wiring capacitance of 0.316 uF.\nSystem Configuration: In an individual system configuration, the indoor phone is installed in the hazardous work area, with a cable connection to the isolation barrier unit in the non-hazardous area. For large communication system configurations or in settings where space is limited, a rack barrier may be used. Please note that the rack barrier and additional outdoor phone units that may be required for a fully functioning communication system do not come with this indoor telephone\/isolation barrier system.\nIf configured as a master\/slave system, the master unit controls the speaking and listening function of the slave units. When the master unit€™s talk mode is being used, the slave units are automatically in listening mode. When the master unit is not being used in talk mode, the slave units will automatically default to talk mode which allows the master to receive audio while allowing hands-free operation for the slave units.\nIsolation Barrier Installation: The unit must be wired in accordance with Pub. 42004-380, Control Drawing 73242, to ensure intrinsic safety. Telephone system wire must be connected to the Isolation Barrier Unit only and not directly to the IS communication device. Shielded cables must be used when multiple IS telephone wires are routed together to prevent cross-talk. The shield must be grounded to an IS ground and connected only at the Isolation Barrier. There are four mounting holes (0.280-inch diameter) on this unit.\n\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"LARSON ELECTRONICS","offers":[{"title":"Default Title","offer_id":38363919057077,"sku":"PL3-EPPH-229AH","price":8212.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/PL3-EPPH-229AH.jpg?v=1628565151","url":"https:\/\/getcahits.com\/products\/pl3-epph-229ah","provider":"PuriLite","version":"1.0","type":"link"}
