7810iR-ent Internet/Intranet Alarm Receiver Installation and Setup Guide
1.0 contained in the Honeywell products has NIST approval. Listings for this approval can

Encryption (Enterprise Application)
The previous paragraph described general encryption, and how it functions with AlarmNet.
When used in a Private closed network or Enterprise installations, some additional processes
are required to support encryption. In an enterprise installation the 7810iR-ent takes on the
server function that exists in the AlarmNet Internet installation.
Installation Key (Enterprise Application)
At installation a 10-digit installation key needs to be programmed into every device in the
network. This 10-digit key should be the same for all devices used in the Private LAN mode.
The purpose of this key is to encrypt the private KEY of each subscriber device as it is
registered to the 7810iR-ent so this sensitive data is never sent in the clear. This KEY is
only used for registration purposes and cannot be used for supervision or alarm
transmission. Once a device is registered the 7810iR-ent will have a copy of the 7845i-ent's
factory KEY. From this point on, the unique factory key is used for communications.
Recovery Mode (Enterprise Application)
Recovery Mode is only applicable when in Private LAN Mode. In the event of a failure of the
7810iR-ent requiring the replacement of the hardware or the erasure of its memory the
7810iR-ent supports a Recovery Mode (when in Private Mode only). In Recovery Mode the
7810iR-ent is programmed with the same 10-digit installation key. When a 7845i-ent
communicates with the 7810iR-ent and is found not to exist in its database, a special
response is sent back to the 7845i-ent requesting it to re-register itself. The 7845i-ent then
register's using the 10-digit installation key. When all accounts have been recovered,
Recovery Mode can be turned off to provide better control of registration.
About the 7810iR-ent
The 7810iR-ent is the receiving end of the AlarmNet system. Using a 10-BaseT Ethernet
connection, the 7810iR-ent receives Contact ID alarm messages and ADEMCO High Speed
supervisory messages from the protected premises and locally displays them. The 7810iR-
ent can be used in stand-alone mode where, messages are displayed on the LCD touch
screen, or they can be routed to either a LRR line card in a Listed 685 Receiver, an MX8000
Receiver or directly to central station automation equipment. (Direct routing to central
station automation equipment has not been evaluated by UL).
