Page 48: Reset
To reset a detector when in it is in alarm state, disconnect the power. Functional Testing The detector can be tested for proper functioning using the Manual Built-in- Test or the SPECTREX IR3 Flame Simulator - FS-1100. 7.4.1 Manual BIT Test Momentarily connecting PIN number 11 (yellow wire) with PIN 2 (black wire) causes a manual BIT to be performed. -
Page 49: Safety Precautions
The 1Hz LED flashes green. Aim the SPECTREX Flame Simulator Model FS-1100 at the target point of the detector (see Figure 14: Flame Simulator), in such a way that the radiation emitted by it is facing directly towards the detector. (See IR3 Flame Simulator FS-1100 on page 57) Press the operation button once. - Page 50 www.acornfiresecurity.com www.acornfiresecurity.com...
