Lift emergency phones are a critical safety system in modern buildings. They allow passengers to contact assistance if a lift stops or experiences a fault.
If a lift emergency phone stops working, it can create serious safety risks and may cause the lift to become non-compliant with Australian safety standards.
This guide explains what happens when lift emergency phones fail, why these systems sometimes stop working, and how building owners and strata managers can prevent communication failures.
Why Lift Emergency Phones Are Critical
Lift emergency phones allow trapped passengers to communicate with a responsible person or monitoring centre.
When the emergency button inside the lift is pressed, the system should automatically connect to:
- a building manager
- concierge or security
- lift maintenance provider
- monitoring centre
This communication allows building staff to organise assistance quickly.
Without a working communication system, passengers may not be able to contact help.
Compliance Requirements in Australia
Lift emergency communication systems in Australia must comply with AS 1735, which covers lift safety and communication requirements.
Under these standards, lifts must provide:
- a two-way voice communication system
- automatic connection to a responsible person
- reliable operation at all times
- backup power where required
If the communication system is not operational, the lift may be considered non-compliant.
In some cases, lift inspectors may require the lift to be taken out of service until the issue is resolved.
Common Reasons Lift Phones Stop Working
Several factors can cause lift emergency phones to fail.
PSTN Network Shutdown
Many older lift phones rely on copper landline services (PSTN). As these networks are decommissioned across Australia, some lift phones lose connectivity.
Faulty Communication Modules
Older lift phone hardware may fail due to age, environmental conditions, or electrical faults.
Power Supply Problems
If the communication system does not have adequate backup power, it may stop working during power outages.
Poor Mobile Signal
Some lift communication systems rely on mobile networks. If signal inside the lift shaft is weak, the phone may fail to connect.
Misconfigured Call Routing
Incorrect configuration can prevent the emergency phone from connecting to the correct response number.
Risks of a Non-Working Lift Emergency Phone
A faulty lift communication system can create several risks for building owners.
Passenger Safety
Passengers trapped in a lift may not be able to contact help.
Compliance Issues
Building inspectors may determine the lift does not meet safety requirements.
Building Liability
If an emergency occurs and communication systems fail, building owners may face legal risks.
Service Interruptions
Some lift maintenance providers may disable lifts until communication systems are restored.
How Modern Lift Communication Systems Improve Reliability
Many buildings are upgrading their lift communication systems to modern technologies.
Common solutions include:
Cellular Lift Phones
4G-based lift communication units provide reliable connectivity without relying on copper phone lines.
Dual Communication Paths
Some systems include multiple communication methods to ensure calls connect even if one network fails.
Remote Monitoring
Modern lift communication systems can automatically send alerts when faults occur.
Battery Backup
Backup power ensures communication remains available during power outages.
Signs Your Lift Phone May Need Upgrading
Building managers should consider upgrading lift communication systems if:
- the system uses a copper landline
- calls occasionally fail to connect
- there is no backup power
- maintenance providers report communication issues
- the system cannot support modern monitoring features
Upgrading can help prevent future communication failures.
Preventing Lift Communication Failures
Regular maintenance and testing are essential to ensure lift communication systems remain operational.
Building managers should ensure:
- lift emergency phones are tested regularly
- communication systems are monitored for faults
- backup power systems are functional
- outdated communication hardware is upgraded
Working with experienced communication providers can help maintain reliable lift communication systems.
Summary
Lift emergency phones are a critical safety system required in Australian buildings. If these systems stop working, passengers may be unable to contact help and the lift may become non-compliant with safety regulations.
Common causes of communication failure include outdated phone networks, hardware faults, and signal issues.
Upgrading to modern communication technology and maintaining lift phone systems properly can help ensure reliable operation and continued compliance.
