Depending on the sensor mode, testing may be performed with one or more of the
following tools:
Test gas
l
– Detector tester RE6 for smoke detectors
– Test gas REF8-S (recommended)
– Test gas REF8
Hot air
l
– Solo461 heat detector tester kit RE7T
The following table shows which mode may be tested with which test aid.

Sensor mode 1
Sensor mode 2
The fire detectors are highly resistant to deceptive phenomena. This means that
optical fire detectors, for example, will recognize the immediate occurrence of
smoke (such as that which occurs during testing with test gas) as a deceptive
phenomenon and will not trigger an alarm. This is desirable in normal operation;
however, it does make testing with test gas problematical.
To enable detector testing with test gas or hot air, the detector must be switched to
test mode. Testing with test gas or hot air is performed differently on addressed
detector lines and collective detector lines.
Proceed as follows:
1. First switch the zone to 'Test' on the control panel.
2. Then perform the test using test gas.
To trigger a detector using test gas, normally 2...4 gas discharges at intervals of
approx. 2 seconds are required. When the detector is in test mode, activation
takes place after approximately 10 seconds.
The procedures in 'Testing detectors [➙ 44]' may also be used to confirm the
position of the detector.
The corresponding status display on the radio gateway is cleared.

The 'Device localization error' display on the control panel disappears.
