6.1 SafEye Operation
Once the system is positioned, it will monitor for possible specified gases
automatically sending signals to a standard control panel or a PC. This
section describes the alignment, calibration and operation.
Important! Accurate Alignment is essential for proper operation of the
SafEye system.
6.2 Alignment of Unit
Using the Telescope performs full alignment.
Alignment procedure should be performed in two stages: Crude alignment
and fine adjustment.
The Telescope includes a Periscope that consists of a prism and an ocular
located vertical to the Telescope assembly. This allows the user to observe
into the opposite unit perpendicularly to the alignment when access from
the rear of the unit is impossible. For installations where rear access is
possible the Periscope is not necessary. In this case it can be removed by
releasing the Periscope Fastening Screw.
Important Notes:
1 Prior To Telescope Installation, verify that the Telescope and Its Sight
Mounting are free from any dirt to ensure proper alignment according to
factory calibration.
2 Do not attempt to change any factory calibration at the Telescope or its
mounting. This may prevent optimal alignment.
➣ To align the unit (see Figure 4):
1 Make sure that the Detector and the Flash Source are installed properly.
Installation instructions are described in section 5 of this document.
2 Remove the front shield using the two captive screws.
