MSU250 Parts Guide

1. 12VDC Jack – Provides 12 volt DC power to MSU

via a regulated power supply.

2. IR Flasher Outputs – 3.5mm jacks provide output

for either single or dual (MF1, MF1VF, MF2,
MF2VF) low-level flashers.

3. 3-30V AC/DC Status – 3.5mm jack provides

system status to sensors/ keypads via a 12V
power supply attached to a switched outlet on
the system receiver or a 12V trigger output.

4. 12V Output – When 12 volts is detected at the

status jack (#3) the 12V output jack will output
12V/200mA DC. This is useful for triggering
external devices and system automation.

5. Status/IR Confirmation LED – This LED performs

two functions: (1) it provides a visible indication
of system status via a green LED and (2) confirms
the reception of IR data via a blinking blue LED.

6. Flasher Hi/Lo switch – Setting these switches to

the appropriate position allows you to connect
either a high output flooding flasher (IRB1) or
low output microflashers (MF1, MF1VF, MF2,
MF2VF).

7. Sensor Input – Removable quick connect sensor

plug for connection of IR sensors to the system.
