3.3 Testing Procedures
This section describes the proof testing procedure for proper operation of
the detector. The detector can be tested using the Manual Built-in-Test or
the Spectrex UV/IR Fire Simulator 20/20-311.
The detector performs internal test continuously and automatic BIT test
every 15 minutes for more details refer to Built-In-Test (BIT) on page 16.
This section includes the following topics:
 Automatic BIT Test, page 35
 Testing with Fire Simulator Model 20/20-311 , page 35
3.3.1 Automatic BIT Test
Check that the indicators show normal conditions. See Powering Up on
page 33.
3.3.2 Testing with Fire Simulator Model 20/20-311
The Fire Simulator Model 20/20-311 can be used to simulate exposure of
the detector to a real fire condition. The detector is exposed to radiation at
the required detection level. As a result, the detector will generate a Fire
Alarm signal. See Long Range UV/IR Fire Simulator on page 57 for more
information.
Important: If the detector is exposed to a fire simulator, the Alarm and
Accessory Relays and 0-20mA are activated during the simulation.
Therefore, automatic extinguishing systems or any external devices, which
may be activated during this process, must be disconnected.
➣ To perform Fire Simulator Test:
1 Power up the system and wait up to 60 seconds for the detector to turn
to a normal state. The Power LED turns on.
2 Aim the Spectrex Fire Simulator Model 20/20-311 at the target point of
the detector (Figure 14), in a way that the radiation emitted by it is
facing directly towards the detector. (See Long Range UV/IR Fire
Simulator on page 57).
3 Press the operation button once. After few seconds, a successful test
shows the results shown in Table 16.
