Testing Procedures 35
 USB RS485 Harness Kit P/N 794079-5. Refer to manual TM777050
for programming instructions when using the USB RS485 Harness
Kit.
 HART protocol, refer to Manual 777030 for instructions.
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/IRFire 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
 Manual 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 Manual BIT Test
Important: If the function setup Alarm BIT and/or Auxiliary BIT are set
to Yes (default No), the Alarm, Auxiliary Relay and 0-20mA outputs are
activated during a Manual BIT. Therefore, automatic extinguishing systems
or any external devices that may be activated during BIT must be
disconnected.
➣ To perform a Manual BIT:
1 Verify that the detector is Normal Mode.
2 Initiate Manual BIT. The results of successful and unsuccessful manual
BITs are detailed in Table 11 and Table 12.
3.3.3 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.
