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)
3.
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.
