Here are some important informationabout Sigma S30. Programming a New PIN Code:
The standard PIN code can be changed following thesequence below:
i) Type in to the keypad **
ii) Type in to the keypad the "existing PIN code" then *
iii) Type in to the keypad 92 * "new PIN code" * "new PINcode" #
Programming Remote Keys to the System:
Remote keys can be added or removed to/from the systemfollowing the sequence below:
i) Type in to the keypad **
ii) Type in to the keypad the "existing PIN code" then *
iii) Type in to the keypad 91 * " the number of keys to beused" #
iv) Press the first remote key button until bleep sounds,release and press next key. Continue until all
keys have been taught to the system. Note the maximumnumber of keys is 4 and all keys required
to operate the system must be taught during this operation- any key not included will no longer
operate the system.
Full Programming, Diagnostics and Features
This section contains all the information that the dealersuse for programming and diagnosis of
the Sigma M30 alarm system, using the MK1 keypadprogrammer.. Programming can also be carried
out using a dealers CP1 programmer.
MK1 Keypad Programming Introduction
It is important the keypad buttons are not pressed tooquickly-
Each time a button is pressed the LED on the keypad willflash once as confirmation. The next button should
not be pressed before this confirmation.
It is important the keypad buttons are not pressed tooslowly-
When in programming mode, if a button is not pressed for aperiod of 10 seconds or more, the alarm will
automatically exit programming mode. This will be confirmedby repeated flashes from LED on the keypad.
You must wait until the LED stops flashing and then startagain.
All programming functions are entered after typing * andthen the programming PIN code. The programming
PIN code is 17856.
To enter the programming PIN code, the alarm system mustfirst be armed and then disarmed using a valid
remote key. (Or keypad using the PIN code)
* 17856 * must then be entered within 30 seconds ofdisarming the system. This is then followed by a 2
digit function code, then another * and then sometimesoptional parameters as shown in the following tables.
It is important to remember the * key is used to separatethe various parts of the code like this:
* programming PIN code * function code * parameter #. The# key is pressed at the end of all
sequences and is used like the "enter" key on a computer keyboard.

Setting Up Pre-set Programs:
Keying in the following sequences on the keypad sets up afixed set of features, which can be used as a
starting point for further tailoring:
* 17856 * 80 # everything off, lock and unlock pulses 1second.
* 17856 * 81 # as for * 80 above, with auto-rearm on.
* 17856 * 82 # as for * 80 above, with auto-arm on.
* 17856 * 83 # as for * 80 above, with auto-rearm andauto-arm on.
* 17856 * 80 # Default setting configures the values shownin the previous tables 1, 2 and 3. Hope this will help you. Good Luck.
