So if I install a dual monitor module (MDF-300 by Honeywell) and set the address to 159, what happens to the second set of monitoring contacts and how will my firelite panel react to this circumstance?

If you check their website, you will see that if the base address is 159, it will also automatically take 160 for the second set of contacts.

But 160 is not a valid address on a firelite panel. 159 is the highest acceptable address.
Can you move around the addresses on any of the sensors to free up 158? Then you can set it to 158 and it will use 158 (159) ...
Also what is the panel model number? Some Firelite panels use one series of addresses for both modules and detectors (ie you can’t have a 158 module and a 158 detector) .. others use two separate series of addresses ( you could have a module M158 and a detector D158 and the panel would be a happy guy).
