Vandal-Proof Emergency Hotline Telephone (SIP, 4G, Analog)
Ultra-Rugged Hotline Communication for Critical Environments
The LC202-AD Series is a heavy-duty, hotline emergency telephone engineered for environments where communication failure is not an option. Housed in a corrosion-resistant steel enclosure, it provides a direct, instant link to help the moment the handset is lifted.
Who is it for?
This series is the ideal choice for facility managers, security directors, and infrastructure engineers overseeing high-risk or public-facing locations, including:
Correctional Facilities & Police Stations
Public Infrastructure: Railway platforms, metro stations, and airports.
Urban Safety: Parking lots, stadiums, and shopping malls.
Critical Services: Hospitals, ATM kiosks, and highway SOS points.
The Solution: One Lift, Instant Response
The Problem: In emergencies, manual dialing causes delays, and standard equipment is easily destroyed by vandals or harsh weather. The Solution: The LC202-AD eliminates hesitation with a direct-dial (Hotline) feature. It solves the pain of high maintenance costs and equipment downtime by using a "tank-like" construction that ensures 24/7 availability in any environment.
Why Choose the LC202-AD Series?
Vandal-Proof Engineering: Built with a cold-rolled or stainless steel box and an 83 cm armored cord capable of withstanding heavy industrial use and intentional damage.
Crystal Clear Audio: Equipped with a proprietary digital noise cancellation system and a noise-cancelling microphone, ensuring loud, clear calls even in deafening industrial settings.
Extreme Reliability: Provides over 50,000 hours of uninterrupted MTBF and is fully electrically isolated with electromagnetic shielding to prevent interference or whistling.
Weather & Environmental Protection: Designed to operate in extreme temperatures from -40F to 149F (-40°C to +65°C) with a corrosion-resistant finish.
Plug-and-Play Installation: Simple wall-mounted design that integrates seamlessly into existing infrastructures.
Versatile Connectivity Options
One chassis, three technologies. Select the version that fits your network:
Analog (PSTN): Cost-effective deployment using existing analog lines; compatible with standard PABX systems.
SIP (VoIP): Fully tested for seamless integration with leading providers like Cisco, Avaya, NEC, and Panasonic via PoE.
4G LTE (Wireless): The perfect solution for remote locations without IT infrastructure. Requires only a SIM card and power for instant connectivity.
Technical Highlights
Warranty: 2-year manufacturer warranty.
Compliance: Hearing Aid Compatible (HAC) handset.
Durability: Magnetic reed hook-switch for long-term mechanical life.
Customization: Standard Grey finish; custom colors available upon request.
