In an era where seamless communication and rapid response are critical to operational safety and efficiency, the entrance of an office building serves as a vital point of contact for visitors, delivery personnel, and employees alike. Traditional intercom systems often lack the flexibility, clarity, and user-direct control needed in dynamic corporate environments. To address this, we introduce an enhanced version of the robust JR305-SC-4G Emergency Intercom, now custom-fitted with an integrated LCD display and numeric keypad. This intelligent upgrade transforms a standard emergency phone into a versatile, department-specific communication terminal, empowering users to quickly and accurately connect with the exact internal support they need.
Engineered for Durability and Reliability
At its core, the intercom retains the industrial-grade construction that defines the JR305-SC series. The housing is crafted from Sheet Molding Compound (SMC), renowned for its exceptional strength and resistance to impact, corrosion, and UV radiation. Paired with a front panel made of 304 stainless steel, the unit is built to withstand deliberate vandalism and harsh weather conditions, ensuring uninterrupted service 24/7. With an IP65 ingress protection rating, it is fully dust-tight and protected against low-pressure water jets from any direction, making it perfectly suited for unprotected outdoor installations at building entrances. Furthermore, its components are treated to resist corrosion, a feature validated through rigorous salt spray testing, guaranteeing long-term performance in humid or coastal environments.
Crystal-Clear Communication in Any Setting
Effective communication hinges on audio clarity. This intercom is equipped with advanced acoustic technologies, including a high-sensitivity, noise-cancelling microphone that filters out ambient background noise—from traffic sounds to windy conditions—ensuring the speaker’s voice is transmitted with HD quality. Complementing this is a powerful, built-in 2W speaker that delivers clear and audible output, facilitated by a full-duplex hands-free operation system. A single, large, vandal-resistant metal button remains prominently available for one-touch emergency calls, instantly connecting to a pre-programmed primary security or reception desk. An LED indicator provides clear visual signaling for incoming calls.
The Intelligent Upgrade: LCD Display and Numeric Keypad
The significant customization that tailors this unit for office building use is the addition of a backlit LCD screen and a tactile numeric keypad. This interface revolutionizes user interaction:
ü On-Screen Guidance: The LCD can display a welcome message, simple step-by-step instructions, or a scrollable directory of internal departments (e.g., Security: Ext. 101, Reception: Ext. 102, Facilities: Ext. 103, HR: Ext. 104).
ü Precise Direct Dialing: Users are no longer limited to a single emergency contact. They can directly dial an extension number using the keypad to reach specific departments for non-critical assistance, access requests, or specific inquiries.
ü Visual Feedback: The screen provides real-time status updates, such as "Dialing...," "Connected to Security," "Call Ended," or configurable text prompts, greatly enhancing the user experience and reducing uncertainty.
ü Streamlined Operations: This system alleviates the burden on main reception by directing calls precisely, leading to faster response times and more efficient internal workflow management.
Powerful 4G Connectivity and Centralized Management
Leveraging reliable 4G LTE cellular networks, this intercom operates independently of traditional copper telephone lines, ensuring connectivity even if landlines are compromised. It supports a wide range of global 4G frequency bands via selectable Quectel EC25 series modules, ensuring compatibility with local network operators worldwide. A standout feature is its remote configurability and management via SMS. From a central location, facility managers can:
² Update auto-dial numbers for the emergency button.
² Set or modify the call duration timeout (configurable between 6-8 minutes).
² Receive diagnostic SMS alerts for events like low input voltage, weak cellular signal, or speaker/microphone faults.
² Monitor the device's operational status without physical inspection.
Designed for Simple Integration and Sustainable Operation
The unit features a practical wall-mounted design with all cabling entering through a secure M16 gland at the rear, protecting connections from tampering and environmental damage. Its power requirements are minimal, consuming only 0.3W in standby and 1.5W during active use, contributing to lower energy costs. Designed for extreme climates, it operates flawlessly in temperatures from -40°C to +65°C and can be stored in conditions from -40°C to +75°C. With a Mean Time Between Failures (MTBF) exceeding 50,000 hours, it promises exceptional long-term reliability and minimal maintenance.
Certifications and Versatility
The product is certified to CE, FCC, RoHS, IK10, and ISO9001 standards, attesting to its safety, electromagnetic compatibility, environmental responsibility, and manufacturing quality. While the enhanced LCD and keypad version is ideal for office building entrances, corporate campuses, and business parks, the robust base design also makes it suitable for a vast array of demanding environments such as hospitals, schools, transportation hubs, and industrial facilities.
Upgrade your building’s first point of contact to a smart, direct, and resilient communication solution. The enhanced JR305-SC-4G Intercom with LCD and Keypad ensures that every call for help or assistance is connected quickly, clearly, and to the right destination.
