The intent of this Proposal Invitation is to solicit sealed Proposals to establish a contract for various types of Fire and Security Systems and Monitoring Services that may be procured by Cooperative members. Because individual members require different equipment, supplies, and/or services, this Proposal Invitation is a request for a discount off of catalog or price list for supplies, materials and equipment, a not-to-exceed monthly rate for monitoring and security-related services, and a not-to-exceed hourly labor rate for repair and installation. Purchases can be made by a Cooperative member at any time during the Contract term. Except as provided in section E.4 of the General Terms and Conditions or otherwise in this Proposal Invitation, Vendor shall hold its Awarded Pricing firm during the Contract term. In the event of price decreases, such price decreases shall be allowed for all products.
