SLM Module Installation Guide

  1. Additional SLM4 modules may be added to expand capacity to 16 zones or SLM12-1600 to
    expand capacity to 24 zones. The SL1620 has 20 fixed zones. The SLM4 and SLM12- 1600 module is useable only on the SL1600.
  2. The SL1600 controller will automatically recognize the additional zones as they are installed. No special programming or resetting is required to initialize the modules.
  3. You can insert or remove a module without removing power from the controller
  4. To install a module, push the module into the channels until you feel it lock in place. To remove a module, push DOWN on the center release panel on the top of the module and use the top tab to pull it out.

Note: Modules must be inserted in the sequence of numbered zones. Do not leave any gaps in module positions.
