Pyronix Enforcer internal sounder

I am looking for some guidance on how to wire an internal sounder (twin/quad piezo) to a Pyronix Enforcer panel. I believe the programmable outputs are rated at 70mA which will be insufficient for the sounder requiring 100-200mA.

The installation manual states under 2.1 technical specification section that the I/O boards SAB output is rated at 250mA continuous load however this is misleading as when looking at the explanation of the Enforcer I/O later on in the manual (Section 3.7) states only SCB bells to be used and offers no spec for the Bell output. Is a relay and external power supply the only way of achieving this or am I missing something really obvious?
