12b10 General

12.B1.1 The system within each specific building shall be configured as a distributive (or central as the case may be) control and monitoring system. All computing devices, as designed in accordance with FCC Rules and Regulations Part 15, shall be verified to comply with the requirements for Class A computing devices. The system shall perform all data consolidation, control, timing, alarm, feedback status verification and calculation for the system.

12.B1.2 The system controller (or controllers as the case may be) shall function as the overall system coordinator, perform automatic energy management functions, control peripheral devices and perform calculations associated with operator interactions, alarm reporting, and event logging.

12.B1.3 The system shall have at least 48 hours of battery backup to maintain all volatile memory and the real time clock.

12.B1.4 The system shall have a battery backed uninterruptible real time clock with an accuracy within 10 seconds per day.

12.B1.5 The system shall operate on 120 VAC, 60 Hz power. Operation shall continue in accordance with the Detailed Specifications from line voltages as low as 95 VAC. Line voltages below the operating range of the system shall be considered outages.

12.B1.6 The system shall be capable of interfacing with no additional hardware, other than the appropriate cabling, to industry standard terminals/PCs. The interface shall support as a minimum: RS232 EIA port, ASCII character code with baud rate selectable between 3009600 baud.

12.B1.7 The system shall have the capability of connecting to a local terminal/PC or printer to perform all programming, modification, monitoring and reporting requirements of the Detailed Specifications.

12.B1.8 The system shall support a Hayes Smartmodem with full RS232 control signals to communicate with remote terminals and other systems via dial-up voice grade phone lines at a minimum of 1200 baud.

12.B1.9 The system shall accept control programs in accordance with the Software Specifications, perform automated energy management functions, control peripheral devices and perform all necessary mathematical calculations.

12.B1.10 The system central processing unit shall be a microcomputer of modular design. The word size shall be 8 bits or larger, with a memory cycle time less than 1 micro second. All chips shall be second sourced.

12.B1.11 Any control program of a system may affect control of another program if desired. Each program shall have full access to all input/output facilities of the system.

12.B1.12 The system shall bi-directionally transfer data to input/output units and local control units at a minimum of 720 baud.

12.B1.13 The system shall provide signal conditioning to insure integrity.

12.B1.14 The system shall be user friendly and shall allow OWNER to designate appropriate nomenclature for all inputs, outputs programs, routines and menus.
