Cipher Codes
The SR10k supports up to 10 cipher codes. Each code is one to six digits in length -
shorter codes are terminated with the '#' key. Cipher codes, like cards, are assigned a
User Level, and like cards, may cause different output relay action depending on the
direction of the code entry. See the next two sections for more details.
User Levels
Each card and cipher code is assigned a User Level from 1 to 3. The User Level, along
with the selected Operating Mode, determines the result of the card or cipher entry.
For example, Level 1 users cannot activate the door relay in some modes unless an
input sees a closed contact.
Operating Modes
The versatility of the SR10k is based on its ability to confi gure the function of its inputs
and relays to suit different applications.
The action performed on the door strike relay, for example, depends on the direction
of the card (or cipher code) entry, on the User Level, and possibly on the state of one
of the inputs. In addition, the color of the upper reader LED may display the status of
an external device connected to an input, such as an alarm panel's armed/disarmed
indicator.
An Operating Mode is a collection of these functions intended for a specifi c application.
The Operating Modes are described in detail later in this document.
Changing the Operating Mode resets the door strike, held open, and auxiliary relay
times to their default settings. See commands 31 through 34.
Multi-Reader Sites
Up to 16 SR10k's may be linked via a '2-wire' cable. Confi guration, card, and cipher
code database settings can all be made at just one reader and copied to other SR10k's
using simple keypad commands. Modifi cations can still be made at each reader in cases,
for example, where the databases are not identical at every reader.
The data link uses the RS-485 interface standard, allowing the total cable run to extend
up to 4,000 feet. The devices must be connected in a 'daisy-chain' confi guration. Install
the RS-485 termination jumper, J4, on the fi rst and last units only.
This unique feature bridges the gap between complex computer-based integrated ac-
cess systems and the simpler, individually programmed stand-alone access controllers.
Additional Information
1. The LED's on the interface board are defi ned as:
A = Heartbeat and reader status: Fast fl ash: normal. Slow fl ash: Reader
communication lost.
B = Flashes when there is activity on the RS-485 communication bus.
2. Jumper J3: not used.
3. Jumper J4: RS-485 termination, install on fi rst and last units only on the communi-
cation bus, see communication wiring diagram.
