1.9 Silent Walk Test

The Silent Walk Test allows for single person testing of the system. This is done by providing an

audio output that can be used by a radio with a microphone input. The system will produce tones

through the audio output jack to give the inspector a positive indication of system behaviour. The

audio jack should be connected to the Mic In or Line In of a radio. Ensure that the radio is set to

automatically broadcast whenever a signal is sent to it. Alarm and supervisory conditions produce

a 1500 Hz tone, trouble conditions produce a 1000 Hz tone and ground conditions produce a 500

Hz tone. Two short pulses are given for a new condition and one long pulse for a restore. Tones

are generated for input circuits only. The output circuits are not part of the walk test.

To activate the walk test, first connect the radio to the audio output jack. Then activate the walk

test by pressing the Test Mode key. The yellow LED next to Test Mod e will flash while the Test

Mode is active. Conventional circuits and addressable devices will need to be chosen for testing.

While selected for testing, circuit and devices will not activate relays, control modules, bells,

releasers or send signals to monitoring stations on port 3. Any LEDs assigned to the test inputs will

follow the circuit or device state. See the section on the Test Mode key on page 5 for more

information on Test Mode. All circuits and devices not chosen for testing will operate as normal.

If a printer is attached to the printer port, a print-out of all events received by the Unit can be

obtained for cross-referencing with the test procedures. Test signals will be marked as such in the

print-out.
