ACT Verifier
Audible Cable Tracer, Resistance Tester & Fault Finder

VERIFIER is a unique cable tracer that uses variable tones to trace hidden cables and test circuit devices to locate intermittant faults. It enables the engineer to quickly walk-test the circuit under test and audibly locate faults in a fraction of the normal time.

It works by passing an audible tone along the cable and through the connected circuit devices such as alarm contact, PIR's, shock sensors, tampers etc,. The tone is heard through the supplied inductive probe by adjusting the volume control and positioning the probe near the cable or alarm circuit device. This method of testing enables hidden cables to be be traced quickly and faulty devices located first time. By operating and tap-testing, any resistance variations can be instantly identified anywhere along the circuit under test.

Verifyer is designed to audibly test 'normally-closed' and 'end-of-line' resistance circuits. Check out the User Manual below for more detailed information.

Follow Hidden Cables & Pinpoint Cable Faults, EMI & RFI Interference

Listen to the tone to find and follow hidden cables behind plasterboard, carpet, floorboards and above ceilings. Any cable resistance fault, short or break will be heard by a change of tone. Induced EMI and RFI will also be identified by a sound change.

Identify Good and Faulty Magnetic Contacts

Variable tones will identify the difference between normal and faulty magnetic contacts. A distorted tone will indicate a faulty contact. By moving the magnet slowly away from the contact, this will verify any normal or faulty contact AND also test the magnet strength.

Identify Devices Connected to Unmarked Cables

The tone can be heard anywhere along the cable AND from the alarm devices. Operating each device in turn will cause the tone to change. Perfect for testing and identification purposes

Verify the sensitivity adjustment of shock sensors

Placing the amplifier proble near a shock sensor and repeatedly activating it by tap-testing will verify operation, sensitivity and resistance faults. Tones heard will be according to the circuit being normally closed or end-of-line. A good shock sensor will produce a clear, steady low to high tone. A resistance fault will produce a distorted, varying low to high tone.

Test Operation & Sensitivity of PIR Motion Detectors

Positioning the probe near the PIR whilst activating it will verify operation, sensitivity and resistance faults. Tones will change according to the circuit resistance being normally closed or end-of-line. A good PIR when triggered will produce a steady low to high tone. A resistance fault will produce distorted and varying low to high tones. Masking the PIR and tapping the PIR enclosure with a screwdriver will audibly expose wiring connection faults.
