Exclamation Type of wire to use for DSC PC1832

Hello,
I am installing my new alarm system but I run short in wire, which is a 4-22.
The DSC system requires to use wire with 18 to 22 Gauge. I have a bunch of speaker wire with 18 Gauge and I am wondering is it's safe to use for my last device I need to connect to the system. the device is a smoke detector.
Any previous experience on this ?
Thanks.

18 is fine; in fact if you read the specs on the wiring diagram, for fire/smoke circuits, the 18 gauge is the specified size.

The fact that it's speaker wire would only be an issue if you were worried about strict UL specs. Otherwise, wire is wire...

Thanks, MrRonFl. I appreciate that.
One more question: Is it a good thing to install the smoke detector on a wall instead of the ceiling? The ceiling is 9ft high and I'm thinking to install the smoke at a foot lower (at 8 ft height).
Thanks again for your help.

On a wall mount, smokes need to be within 12 inches of the ceiling, but no closer than 4 inches. This is because of a phenomenon called smoke stratification.
