I cannot find any documentation on this. I know that the DB9 pin 1 on the IPSI tn2312bp is used for -48v. Can anyone tell me how many milliamp it is rated for?

I have 4 viking PF-6A emergency transfer units needing 100 milliamp each and I am wondering if it is adequate, or if I should wire a relay to it instead and use a different power supply..

Member "Sparky" sent me this on a related question I had over IPSI power. I hope this helps.

Here is the reply...

the DB9 is not suppose to provide power for anything other than an emergency transfer panel (ie. an 808A), the out current is insufficient.
pins 1&2 give -48V for emergency transfer
pins 4&5 are dry contacts for alarm bell light or indicator
pins 6&7 are for UPS major alarm
pins 8&3 are for UPS minor alarm

1. Connect 1 major (Brown-White and White-Brown) and 1 minor (Orange-White and
White-Orange) alarm input pair to the trunk/auxiliary field from the TN2312BP Adapter DB9
alarm connector. Alarms can be generated on adjunct equipment, sent to the Avaya
media gateway, and recorded and reported as "external alarms." The adjunct equipment
must provide an isolated contact closure across the alarm leads provided by the Avaya
media gateway. The contact must be rated at a minimum of 60 VDC with a current carrying
capacity of 5 mA minimum.
2. Connect an external alarm output (Green-White and White-Green).
3. Note which device connects to which alarm and give this information to your Avaya
representative for troubleshooting purposes.
