Figure 9. Control module in relay output mode:
WARNING
Control Module switch contacts are shipped in the standby state (open). Contacts may have transferred to the activated state (closed)
during shipping.
The module utilizes a mechanical latching-type relay that can change states due to shock or jarring. The control panel controls this re-
lay with “STANDBY” and “ALARM” control commands. To insure that the switch contacts are in the standby state, control modules
must be made to communicate with the panel before connecting circuits controlled by the module.
