MSU480 Parts Guide
1. 12V DC 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 (MF2, MF2F, MF2D, MF2DF)
low-level flashers.
3. 3-30V AC/DC Status – 3.5mm jack provides system
status to sensors/ keypads via a 12 volt power sup-
ply attached to a switched outlet on the system
receiver or a 12 volt trigger output.
4. 12VDC/200mA Output – When 12VDC voltage is
detected at the status jack or a discrete IR com-
mand is issued 12VDC/200mA is output.
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/Low switch – Setting these switches to
the appropriate position allows you to connect
either a high output flooding flasher (IRB1) or low
output MicroFlashers (MF2, MF2F, MF2D, MF2DF).
7. Contact Closure Switch – Two position switch that
determines if the contact closure is activated by
either (a) the presence of status or (b) discrete IR
commands.
8. Contact Closure Plug – Three position quick con-
nect plug for connecting either a NO (normally
open) or NC (normally closed) contact closure
device to the MSU480
9. Sensor Input – Four position quick connect plug for
connecting IR sensor and/ or IntelliPad‚ to the
MSU480.
10. Sensor Input Labels – Recessed label slot for instal-
lation of preprinted room identification labels.
