5.2 Testing a Detector
Raise Testifire up to the detector to be tested and place it centrally over the
detector. As the detector enters the clear cup and interrupts the built-in infrared
sensor in the head of Testifire, the selected tests or sequence of tests, begin.
NOTE:
It is very important that the detector under test is in the correct position
within the clear cup for a successful test to take place. The detector should sit on the
platform and the top of the inner clear cup should be parallel to the detector base.
Ideally, the bellows should seal against the ceiling surface (Fig 28).
When testing high profile detectors, it may be necessary to remove the inner clear
cup to enable the detector to sit in the correct position for a successful test. The
inner clear cup has a semi-circular cut-out on the side nearest to the user interface.
Place your finger in the cut-out and carefully lift out the inner clear cup (Fig. 29).
:
Ideally, the detector LED should be visible through the inner cup of the head
TIP
unit. In some instances this is not possible. To improve visibility of the detector LED,
lower Testifire briefly, (2 seconds maximum), raising it again to continue the test.
For single-stimulus tests, the ‘Test Type’ LED will remain illuminated in one colour only, and for a sequence of
single-stimulus tests it will show the colour relating to the current test. For a multi-stimulus simultaneous test,
it will show all the colours relating to the stimuli in the test, alternating its colour repeatedly between them.
If after 2 minutes the test has not completed, Testifire will time out.
When the detector is activated, remove Testifire by lowering it gently. Testifire will return to ‘STANDBY’
mode as the Infrared beam is re-established and the ‘Status’ LED will flash slowly again.
Testifire may be used in a variety of modes for detector testing. Multiple stimuli (Smoke, Heat,
CO) may be tested either simultaneously (all at once) and/or sequentially (in various
combinations). The stimuli and their method of operation are described in the following sections.
5.1 Sounder Option
Two different ‘beeps’ are emitted from Testifire. A short ‘beep’ when pressing the
‘Power-On’ button and for a key press (‘Keypad’), and a longer 2-second ‘beep’
for errors (‘Warning’).
In some environments the sound may not be desirable. Testifire has an option that
allows both types of ‘beep’ to be disabled. Once disabled, the sound stays disabled
until it is manually enabled again or a ‘SYSTEM RESET’ takes place. (see Section 6.2).
To disable the sound, press the ‘MENU’ key and using the ‘UP’ and ‘DOWN’ keys
on the keypad,
navigate to ‘Sounder’ (Fig. 26) and select using the ‘ENTER’ key .
Use the ‘ENTER’ key also to select ‘ON’ or ‘OFF’ for the ‘Keypad’ and ‘Warning’
sounds (Fig. 27).
Once the stimulus has been selected, the ‘Test Type’ LED will change colour to indicate the following:
Red = Heat Test Blue = Smoke Test Green = Carbon Monoxide Test Clear = Clearing
The ‘Status’ LED provides feedback on the modes of operation and alerts
you to errors or when a smoke or CO capsule is empty or incorrectly
fitted. The Indicating LED Reference Chart details all of the variations
(see Section 5.13).
