How do I add more wired zones to the IQ Pro?

To add wired zone inputs to an IQ Pro alarm system, you will need to add the HSM2108 zone expander. You will need to know how many wired inputs you will need as the main board offers 8 inputs, and each HSM2108 adds 8 more wired inputs per board. 

The plastic cabinet version of the IQ Pro can hold 4 HSM2108 zone expanders, and the metal cabinet version can hold up to 6 HSM2108 zone expanders. If additional cabinet space is needed we also offer the PC5003c, a 12x12in DSC cabinet designed to house DSC modules such as the HSM2108 and HSM2204.
