2.8.5 Heated Optics
The heated optics can be defined as one of the following modes:
•
Heated Mode
•
OFF: Not operated
•
On: Continuously
•
AUTO: Per temperature change
In AUTO mode, the default HEAT ON setting is 68°F (20°C). Heating stops when the
temperature is 27°F (15°C) above the start temperature.
You can define the start temperature below which the window will be heated. The
temperature can be defined between 32°F and 122°F (0°C to 50°C).

OPERATING THE DETECTOR
This chapter describes how to power up and test the detector. It also includes some very
important safety checks that you should make before operating the detector.
3.1 Powering Up
This section describes how to power up the detector. Follow these instructions carefully to
obtain optimal performance from the detector over its life cycle:
Ø
To power up the detector:
24
Turn on the power.
25
Wait approximately 60 seconds for the detector to finish the start-up procedure.
Applying power initiates the following sequence of events:
•
The yellow LED flashes at 4 Hz.
•
BIT is executed.
If successful, the green LED flashes at 1 Hz and the FAULT relay contacts close, mA
output is 5 mA.
26
Enter to Normal mode.
Note : The majority of detectors are used in the default non-latching alarm mode. Only
perform a Reset when the Latching alarm option has been programmed.
Ø
To reset a detector when in it is in a LATCHED ALARM state:
•
Do one of the following:
•
Disconnect power (Terminal Number 1 or Terminal Number 2).
or
•
Initiate a Manual BIT.
3.2 Safety Precautions
After powering-up, the detector requires almost no attention in order to function properly,
but the following should be noted:
•
Follow the instructions in this guide and refer to the drawings and specifications.
•
Do not expose the detector to radiation of any kind unless required for testing
purposes.
•
Do not open the detector housing, while power is applied.
•
Do not open the electronic compartment. This part should be kept closed at all times
and only opened in the factory. Opening the electronic component side invalidates the
warranty.
