Holland Electronics HMS-8A Multiswitch

[LordPong]

I am trying to find out the power supply requirements for the HMS-8A multiswitch. Specifically, I need to know the:

1. Input Voltage.
2. Current Required.
3. Tip Polarity.

Calls to Holland Electronics result in a sales pitch for the HMS-PS adapter

Would this help?
HMS-PS Power Supply for HMS-4APE & HMS-8A
Unfortunately, no specs on that page.
Google searches weren't very much help.

Their 5x8 multiswitches use a 24 volt power supply@ 1 amp.
Other 3x8 multiswitches use an 18 volt 500 mA power supply.
Tip is positive and sleeve is negative.
