Project Overview

As part of Singapore’s ongoing efforts to enhance urban safety and improve the quality of public infrastructure, several major parking facilities have recently been equipped with JR304-SC-AL Emergency Intercom Systems supplied by J&R Technology.

The project’s objective is to establish a reliable, vandal-resistant, and weatherproof emergency communication network that allows users to reach assistance instantly in emergency situations. With its solid construction, proven performance, and compliance with international standards, the JR304-SC-AL was selected as the ideal solution for Singapore’s demanding urban environment.

Product Highlights: JR304-SC-AL Emergency Intercom

The JR304-SC-AL is a heavy-duty emergency intercom designed for long-term performance in public spaces. Its cold-rolled steel body and brushed stainless-steel faceplate provide outstanding durability, impact resistance, and protection against vandalism.

Certified to IP55–IP65 standards, the unit is fully protected against dust and water ingress—ensuring stable operation even during heavy rain or high humidity. Corrosion-resistant components and successful salt spray testing make it especially suited for coastal and tropical conditions.

Key Features

• One-Touch Operation: A single vandal-proof metal button enables fast, hands-free emergency calling.

• LED Status Indication: A built-in LED indicator flashes during active calls, allowing quick identification in large parking areas.

• High-Quality Audio: Equipped with a noise-cancelling microphone and 2W speaker for clear, reliable communication in noisy environments.

• Easy Installation: Wall-mounted design with protected cabling enhances reliability and simplifies maintenance.

Integration and Technical Advantages

Operating within a 24–65 VDC analog line range, the JR304-SC-AL draws power directly from the telephone line, eliminating the need for an external power source. It can be integrated directly into PABX/PSTN systems or connected via a voice gateway for use with SIP-based VoIP networks.

Through DTMF remote configuration, system administrators can set parameters such as auto hang-up and scheduled dialing—allowing automated system checks and ensuring continuous operational readiness.

Quality and Reliability

The JR304-SC-AL complies with CE, FCC, RoHS, IK10, IP65, and ISO9001 standards. With a Mean Time Between Failures (MTBF) exceeding 50,000 hours and an operating temperature range from -40°C to +65°C, the system guarantees stable performance in both indoor and outdoor environments.

Optional Accessories

For enhanced functionality, optional accessories such as LED beacon lights, broadcast horns, and auxiliary call buttons are available, improving both visibility and response coordination in emergency situations.

Conclusion

The successful deployment of the JR304-SC-AL Emergency Intercom System marks an important step in strengthening safety measures within Singapore’s parking infrastructure. Combining durability, superior audio clarity, and flexible integration, this system delivers a future-proof solution for urban safety communication.

J&R Technology remains committed to delivering high-quality industrial communication products that safeguard lives and support smarter, safer public environments around the world.
