This is Addendum 3 to the Phase 2 Technology Upgrades project for Dearborn Heights School District No. 7, issued by designer AE Tech Design on December 14, 2020. The addendum clarifies and revises specifications for a paging system installation at Annapolis High School, including removal of the network I/O module VE-8048AR and associated connections from the system design and correction of the speaker part number from V-9062 to VC-9062. The project requires installation of new Category 6 cable for all speakers identified on sheets T502 and T503, whether existing or new installations, and 4-conductor stranded cable for speakers receiving power and speaker feeds. The addendum provides detailed Q&A responses addressing bidder inquiries regarding cable specifications, part numbers, and the lockdown button functionality that was removed from the high school's system configuration. The bid receipt date remains unchanged by this addendum.

The addendum includes updated paging system riser drawings showing the complete technology infrastructure across multiple tech closets serving various facility areas including classrooms, corridors, gymnasium, cafeteria, media center, auditorium, and office spaces. The system utilizes Valcom components including multiple speaker models (VC-9062, V-1020C, V-9871, V-1030M, V-1030C-GY, V-C806PK), network audio ports, talkback gateways, power supplies, and a server. No pricing information, set-asides, incumbent details, or funding sources are specified in this addendum document.

ADDENDA 009113 - 2

C. Q: Can you please verify the Valcom Part VE-9062 for icon S1: should it be V-9062 or VC-9062

A: The correct part number is VC-9062, system riser has been updated.

D. Q: On Sheet T502 in the upper left hand corner, in the box labeled Tech Closet -A (MDF). The block diagram indicates there is a network IO module required and a line labeled “switch” connecting the IO module to the existing access control system. Is that control module to provide a contact closure to activate a door release mechanism? If so, how many contact closures or doors release mechanisms need to be activated by the network IO module?

A: In a typical scenario, the paging system accepts a contact closure from the access control system, through the network IO module. In the event that the lockdown button is pressed, the paging system will send an audible notification of the lockdown. However, this was supposed to be removed from the drawings as the High School does not have a lockdown button. VE-8048AR and associated connections have been removed from the system riser.
