78 MPA2C3 Installation Guide
Red RJ45 Door terminal
The default settings for the door inputs are, using red RJ45 door terminals:
The REX input is a Normally Open (NO) input, without end-of-line (EOL) resistors.
• You can connect the NO contacts of the REX switch or sensor immediately to the
REX and GND input of the panel.
DrCnt input is a supervised, Normally Closed (NC) input, set for 2.2 kOhm EOL
resistors.
• You can connect the NC contacts of the Door contact or sensor with two 2.2
kOhm resistors to the DrCnt and GND input of the panel.
• When using the MPA2S5, there is no need to add the two EOL resistors at the
• Door Contact or sensor. See picture per below.
