*1 The Above KEN assignments for Relay type output modules assume that all power supplying the switched
contacts (devices switched on/off by the output expander) is supplied via a different feed/ PSU.
*2 Remember that the maximum allowable current-draw from the Matrix for External devices is 0.6A (plastic
case) / 1.1A (metal case). Any requirement exceeding this must be provided by a separate power supply.
Where a power supply is added for use with an output expander, the 0V of the supply should be connected at
the expander.

1.9.3 System Examples
A Matrix System is required to provide the following:
 6 PIR Detectors (15mA each)
 A bell-box (max. current draw 400mA) connected to PGM1
 2 Matrix ICON Keypads (60mA each), one 50m away, and the other 100m away
 A Matrix Transistor Output Expander (30mA) with 3 LEDs (10mA each) and 3 buzzers (12mA
each) controlled by the outputs (accompanying the keypad 100m away) power supply.
From the above example, the total current drawn from the panel would be:
TOTAL Detectors Bell RKPs

LEDs Buzzers
0.706A 6 X 0.015 1 X 0.400 2 X 0.060 1 X 0.030 3 X 0.010 3 X 0.012
The maximum current available for external devices from the Matrix PCB is 0.6A. Therefore, this installation
would require an additional power supply.
Before we can calculate an acceptable wiring arrangement we must know the ‘KEN’ value for each device on
the keypad bus. From Table 1 we know that each keypad has a KEN of 1. The Transistor Output expander
controls the LEDs and buzzers, which together give a total current of 66mA (3x10mA + 3x12mA). From table
1 a transistor output expander with a current sink of 66mA falls into the <90mA criteria which corresponds
with a ‘KEN’ of 2.
