ALPHA 5000 (SHIELD)
ALPHA
5000 AUTO ALIGN BEAM DETECTOR
The
Alpha 5000 System is an auto-aligning, self-correcting infrared beam smoke
detector. Up to 2 detector heads can report to a single ground level
controller. In addition, each system controller houses two pairs of fire and
trouble relays, one per detector. Once the detector head is installed, using
the easyfit mounting system an integral LASER can be activated. This allows the
reflective prism to be located quickly and with confidence.
The
Auto-Align function ensures proper alignment and maximum signal during the beam
installation. AutoOptimise automatically steers and maintains the beam in the
optimum position for reliable performance. The signal generated in the
transmitter element and reflected by the prism back to the receiver element is
analyzed for the presence of smoke. The internal microprocessor determines an
alarm condition when a predetermined level obscuration is reached.
