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 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 (5.7 years) of uninterrupted MTBF and is fully electrically isolated with electromagnetic shielding to prevent interference or whistling.
Plug-and-Play Installation: Simple wall-mounted design that integrates seamlessly into existing infrastructures.
Supports two relays to remotely control external devices
Built for Harsh Environments
Heavy-duty cold-rolled steel housing
Tamper-resistant screws
Vandal-Resistant Cord: Features a heavy-duty armored steel cord. Standard length is 83 cm (approx. 32.7 inches).
Ligature-resistant cord Option: To minimize risk in correctional and psychiatric environments, we offer ligature-resistant cords with a reduced length of 12 to 14 inches (30–35 cm). This design prevents self-harm while maintaining essential communication functionality
Electromagnetic shielding and grounded enclosure
Weather & Environmental Protection: Designed to operate in extreme temperatures from -40F to 149F (-40°C to +65°C) with a corrosion-resistant finish.
Clear Communication in Noisy Areas
Noise-cancelling microphone for intelligible speech
High audio output with no acoustic feedback
Hearing Aid Compatible (HAC)
Ringing volume 90~95 dB (A)
Magnetic reed hook switch without moving parts for reliable operation
Versatile Connectivity Options
