hooking up a fire alarm Sync Module without a panel

[logycam10]

And are truealert horns 12 or 24 volts?

@logycam10 All of Simplex's DC devices are 24VDC. I don't think they ever carried a 12VDC device sense their DC panels are 24VDC.

Can you use that as a coding relay?

@logycam10 I suppose you could, but it'll only do code-3.I'm not sure about ESTs or Wheelock's but Simplex Smart Sync mod will do code-3, slow and fast march time.
