Identify the equipment
Enter the manufacturer, model, part number or terminal markings before electrical testing begins.
Intercom MasterComing soon
Step-by-step intercom fault finding
A new practical tool that helps engineers identify equipment, carry out the correct electrical tests and follow the fault logically until it is repaired or the faulty part is identified.
Follow one clear test
Each screen explains what to open, what tool to use, where to place the probes and what result to expect.
Record the outcome
Save the test results, finish when the fault is repaired or request the correct replacement equipment.
Planned features
What the fault finder will do
Designed for experienced engineers and engineers carrying out an intercom test for the first time.
Identify the system
Search by manufacturer, model, part number, system type or the terminal markings found inside the handset or monitor.
One test at a time
Shows one clear physical action on each screen, followed by simple result buttons that select the correct next test.
Exact meter instructions
Explains the meter setting, which terminals to use, where to place each probe and whether the equipment should be powered.
Help for every step
A Help button explains which tool is required, how to set it up, the expected result and what different readings mean.
Handset identification
Enter up to eight connected terminal markings and compare possible handsets before wires are disconnected or moved.
Handset conversion guidance
Maps the old handset functions to a compatible replacement, including call type, common, microphone, speaker and door release.
Modern systems
Covers two-wire digital systems, IP and PoE equipment, network switches, Cat5/6 cabling and GSM entrance panels.
Audio and video testing
Separates speech, call, video, power and programming faults and explains when a compatible test monitor or CCTV tester is required.
Door-lock fault finding
Uses different tests for magnetic locks, fail-safe locks, fail-secure strikes, CISA locks and electronic bolt locks.
Power-supply testing
Guides the engineer through AC or DC output tests, voltage under load, cable voltage drop, branch faults and battery backup.
Safety workflow
Records PPE, risk assessment, asbestos-register checks, leaking water, unsafe doors and conditions requiring office advice.
Engineer test report
Planned reports will include the job details, equipment, tests, readings, repair, photographs and engineer information.
Request replacement parts
When testing confirms a faulty handset, panel, power supply or lock, the engineer can send the details to Intercom Master for a quotation.
Continuously improved
New manufacturer information, verified terminal connections, real fault examples and improved testing routes will be added over time.
Built for working intercom engineers
The tool is being developed from Intercom Master's practical fault-finding methods and verified equipment information.
