The alarm message shall include the name of the calling location, the device that generated the alarm, and the alarm message itself.

7. System Configuration:

a. Network control strategies shall not be restricted to a single digital controller, but shall be able to include data from all other network devices to allow the development of global control strategies.

b. Provide automatic backup and restore of all digital controller databases on the workstation hard disk. In addition to all backup data, all databases shall be performed while the workstation is on-line without disturbing other system operations.

2.5 NETWORK AND DEVICE NAMING CONVENTION

A. Network Numbers:

1. Siemens network numbers shall be based on a "facility code, network" concept. The "facility code" is the VAMC’s or VA campus’ assigned numeric value assigned to a specific facility or building. The

"network" typically corresponds to a "floor" or other logical configuration within the building.

2. The network numbers are thus formed as follows: "Net #" = "FFFNN" where:

a. FFF = Facility code (see below)

SECTION 23 09 23 Page 24 of 39

b. NN = 00-99 This allows up to 100 networks per facility or building

B. Device Instances:

1. BACnet allows 4194305 unique device instances per BACnet internet work. Using Agency's unique device instances are formed as follows:

"Dev #" = "FFFNNDD" where

a. FFF and N are as above and

b. DD = 00-99, this allows up to 100 devices per network.

2. Note Special cases, where the network architecture of limiting device numbering to DD causes excessive subnet works.
