(Elevator Emergency Intercom Systems) and Optimization Guide for Spare Parts Configuration
In elevator safety systems, the emergency communication module (elevator emergency intercom system) is often regarded as the “last lifeline.” When an elevator breaks down or a passenger becomes trapped, a stable and reliable communication system is critical to ensuring timely and effective rescue.
However, in real-world maintenance work, communication failures are far from uncommon. This article takes an in-depth look at common problems in elevator communication systems and provides professional optimization recommendations for elevator spare parts configuration.
1. Three Common Problems in Elevator Emergency Communication Systems
Signal Interference and Excessive Noise
In older residential buildings or underground areas with strong signal shielding, analog communication systems often suffer from heavy electrical noise or frequent call drops. This is usually caused by damaged shielding in the traveling cable or aging communication modules.
Backup Power (Battery) Failure
According to safety regulations, elevator emergency communication must remain operational for at least one hour after a power outage. Since batteries are consumable components, long-term lack of discharge activation often leads to swelling or rapid capacity degradation. As a result, the emergency call button may become completely unresponsive at critical moments.
Incompatibility in Five-Way Intercom Systems
With ongoing digital upgrades, many projects attempt to connect legacy intercom systems to IP networks or GSM gateways. If the selected elevator spare parts use inconsistent interface protocols, communication between the car, machine room, pit, and monitoring room may fail.
2. Optimization Strategies: How to Improve Communication System Reliability
To ensure reliable emergency communication, A-FLY, a globally leading elevator and escalator spare parts supplier, recommends optimization from the following three dimensions:
Upgrade to Digital Communication Solutions
Adopting wireless digital intercom systems with strong anti-interference capability, combined with high-quality audio processing boards, can effectively filter background noise and ensure clear voice transmission during emergency calls.
Strengthen Power Redundancy Design
Equip the system with intelligent backup power management modules featuring real-time monitoring. During routine maintenance, select dedicated batteries with longer service life and better high-temperature resistance to reduce replacement frequency and failure risk.
Choose One-Stop Compatible Spare Parts Solutions
For elevators of various brands, if only a single component is damaged—such as the intercom main unit or handset—it is usually more cost-effective to replace it with an original brand part to minimize installation and protocol compatibility issues.
However, if the original intercom system is 20–30 years old, or if system expansion or modernization is required, A-FLY recommends a complete intercom upgrade solution.
We offer wireless, bus-type, and four-wire communication solutions. Contact us to receive a free elevator intercom upgrade and retrofit proposal.
