The NMM-100-10 ten-input monitor module is an interface between a FireWarden series control panel and normally open contact devices in intelligent alarm systems such as pull stations, security contacts, or flow switches. The first address on the NMM-100-10 is set from 01 to 90 and the remaining modules are automatically assigned to the next nine higher addresses. Provisions are included for disabling a maximum of two unused addresses. The supervised state (normal, open, or short) of the monitored device is sent back to the panel. A common SLC input is used for all modules, and the initiating device loops share a common supervisory supply and ground — otherwise each monitor operates independently from the others.
