3.1.3 System Memory

Prior to starting the programming of the PC programmable telephone entry system, you must know the memory capacity and the type of the EEPROM chips that are installed in the unit. This can be determined by inspecting the small chip that has a tag listing the memory size on it. This memory size determines the number of residents, vendors and four-digit entry code numbers that can be stored in the system. If the memory chips are MemPLUS chips, device (card, transmitter) codes, relay hold time zones, security levels, and elevator control functions can be entered into the system memory. MemPLUS chips are identified by the letters “MP” printed on the tag on the small chip. If the tag does not indicate MP, the chips are standard chips and the system will not have advanced feature capabilities. The table below list the valid numbers available with each memory level.

Standard Chip 500	500 MemPLUS Chip
	MP

System	Phone Number	Name	Entry Code	Device Code
Memory	Capacity	Capacity	Capacity	Capacity
25	25	25	25	625
75	75	75	75	1875
125	125	125	125	3125
250	250	250	250	6250
500	500	500	500	8000
1000	1000	1000	1000	8000
2000	2000	2000	2000	8000
3000	3000	3000	3000	8000

IMPORTANT!! MemPLUS (MP) chips must be installed in this system if device (card, transmitter, PIN) codes, tracker expansion boards, or elevator control boards are used with the system. Relay hold open time zones, security levels, and elevator control functions require MemPLUS chips. None of these features are available if standard (non-MP) chips are used.
