Only the D7412GV4 and D9412GV4 have firmware version 2.x available.  The D7212 type panel has been discontinued after GV4 version 1, therefore the version 2 firmware is not available for the D7212GV4.  If the funtionality of  firmware version 2 was needed, then upgrading the D7212GV4 to a D7412GV4 or D9412GV4 is recomended. As an additional option, replacing with a B3512, B4412, B5512 or B6512 may be an excellent option for replacement should the upgrade be desired. Please refer to the B Series documentation on our website at http://us.boschsecurity.com/. ... View more

Alignment by LED: 1. Apply power to the system. 2. Use the supplied interruption sheets to cover the lower optical modules of the transmitter and the receiver. 3. Look into the upper scope of the transmitter 10 cm (3.9 in.) to 15 cm (5.9 in.) from the optical module. Use the turntable to adjust the horizontal angle. 4. Use the horizontal and vertical adjustment screws to locate the receiver in the center of the viewing area. 5. Look at the Level Meter on the receiver to proceed with fine tuning. 6. Use a screwdriver to adjust the angle of the upper optical module. 7. As more beam energy is received, each LED status follows this sequence: ON_Flashes quickly_Flashes slowly=>OFF 8. Continue fine tuning until all LEDs turn off. 9. Remove the interruption sheets from the lower optical modules and cover the upper optical modules of the transmitter and the receiver. Repeat the alignment process for the lower optical modules. 10. When all LEDs turn off, the alignment is complete. Remove the interruption sheets from the optical modules. Alignment Using a Voltmeter: 1. Apply power to the system. 2. Use the supplied interruption sheets to cover the lower optical modules of the transmitter and the receiver. 3. Insert the voltmeter leads into the alignment check terminals. 4. Set the voltmeter to 10 volts VDC. 5. Use a screwdriver and adjust the upper optical modules to obtain the maximum voltage. Note: In an ideal environment, the voltage is 3.0 VDC or above. 6. Remove the interruption sheets from the lower optical modules and cover the upper optical modules of the transmitter and the receiver. Repeat the alignment process for the lower optical modules. Ensure the interruption sheets are removed and beam detector covers are closed when the alignment procedure is complete. ... View more

 An Octopopit addressed for points 65-71 or 129-135 has the dip switch for zone 8 turned on and the zone is shorted. Set dip switch 8 to off on these Octopopits. Zones 72 and 136 are reserved for monitoring the Zonex Data Expansion Loop. When adding a D8128A for use with points 65-71 (D7212B or B1), setting switch 8 to on enables zone 72. When adding a D8128A for use with points 129-135 (D9112B or B1), setting switch 8 to on enables zone 136. ... View more
