Setting up the Master
If you will use the Master to sync clocks, you must first use relays #7 & #8 (terminal block
P1) for synching. If you have an LTR8-512 or LTR8-512M and will use a second clock
type, you must use relays #5 & #6 (terminal block P2) for those clocks

Here are some suggested ways to program your Master’s relays:
1. Eight (8) bell zones that can last from 1 second to 99 seconds. Use this setup if your
Master will not synchronize secondary clocks.
2. Six (6) bell zones and one electro-mechanical wall clock sync control. Use this setup if
your Master will sync only one type of clock in one string.
3. Four (4) bell zones and two electro-mechanical wall clock sync controls. Use this setup if
you will synchronize two clock types, or if you have two strings of clocks (typically 20 to
35 clocks to a string).
The steps below lead you through getting the Master up and running.
Enter your Password

The user password allows you to access user functions, but you must use the administrator
password to access advanced functions. You can change the user password, but you cannot
change the administrator password. To keep the administrator functions secure, only give this
guide to authorized personnel. You can learn more about user passwords in the User’s Guide.
All factory programmed passwords can be spelled out using the letters of a telephone keypad.
For example, the administrator password is 332537 or DEALER.
Enter the administrator password ‘332537’ [DEALER]
