ACT Verifier ACT Verifier
WARNING: VERIFIER IS DESIGNED TO TEST RESISTIVE CIRCUITS ONLY. THE CIRCUIT MUST BE
DISCONNECTED FROM THE CONTROL EQUIPMENT BEFORE TESTING. DAMAGE OR INJURY MAY
RESULT IF CONNECTED TO ANY VOLTAGE SOURCE. IF IT IS USED IN A MANNER NOT SPECIFIED
BY THE MANUFACTURER, THE PROTECTION PROVIDED BY THE EQUIPMENT MAY BE IMPAIRED.
Description
Verifier is an ingenious audible cable finder, resistance tester and fault locator in one easy
to operate unit. The inductive amplifier probe supplied with Verifier enables the operator to
audibly follow hidden cables under carpets, behind plaster and under floorboards throughout
the installation. But that’s not all. It also allows the user to audibly test any resistance devices
connected to the circuit such as; magnetic contacts, PIR’s, shock sensors, tamper switches etc.
Three variable resistance tones (Low 0Ω to high 250Ω, low <250Ω to high 25KΩ, low <25KΩ to
high 250KΩ) change in pitch according to the resistance of the circuit under test. This makes
Verifier ideal for audibly testing normally closed and end-of-line resistance circuits. The higher
the resistance, the higher the tone. When testing any resistance changes will be instantly heard.
A high pitch ‘open-circuit tone’ enables resistance breaks on the cable or device to be pinpointed
easily. This ingenious use of sound makes it simple to identify the difference between good, bad
and intermittent faults.
Verifier makes it quick and easy to locate all manner of faults including; varying resistances,
loose connections, damaged cables, circuit breaks and defective devices during commissioning
and maintenance inspections. It also makes identifying devices connected to unmarked circuits
quick and easy when performing take-over inspections and troubleshooting first-fix installations.
In conclusion, Verifier is an essential and affordable tool for anyone who needs to test and
identify resistance faults first time.

Test Procedure
WARNING: THE RESISTANCE CIRCUIT MUST BE DISCONNECTED FROM THE CONTROL EQUIPMENT
BEFORE TESTING.
1. Securely connect the black lead clips to the resistance circuit under test
2. Connect the green lead clip to earth to maximise the distance the tone can be heard from
the circuit cable
3. Switch Verifier ON which is confirmed by a green LED
4. Switch the inductive amplifier probe ON and set to the desired volume
5. Using the probe, follow the circuit cable under test throughout the installation
6. Holding the probe closer to the circuit cable or device under test, will produce a louder tone
7. Touching or tapping along the circuit cable will audibly identify resistance shorts or breaks
8. Tap testing joint boxes will audibly reveal intermittent resistance connection faults
9. Operating magnetic contacts by slowly moving the magnet away from the contact will
audibly identify resistance variation faults
10. Repeatedly activating PIR’s, shock sensor and tamper switches will audibly verify normal
operation or identify resistance variation faults
