Description

Firstly, the Edwards SIGA-MM1 Monitor Module and SIGA-WTM Waterflow/ Tamper Module are part of Edwards ’ Signature Series system. Also, they are intelligent analog addressable devices used to connect one or two Class B normally-open Alarm, Supervisory, or Monitor type dry contact Initiating Device Circuits (IDC). Besides, the function of the Edwards Est SIGA-MM1 and SIGA-WTM is determined by the factory-loaded “personality code”.

In fact, the input modules gather analog information from the initiating devices connected to them and convert it into digital signals. In addition, the module’s onboard microprocessor analyzes the signal and decides whether or not to input an alarm. Furthermore, the microprocessor in each module provides four additional benefits – Self-diagnostics and History logs, Automatic Device Mapping, Stand-alone Operation, and Fast, Stable Communication.

In general, the Edwards Est SIGA-MM1 and SIGA-WTM modules mount to North American 2-1/2 inch (64 mm) deep one-gang boxes and 1-1/2 inch (38 mm) deep 4-inch square boxes with one-gang covers and SIGA-MP mounting plates. The terminals are suitable for #12 to #18 AWG (2.5 mm2 to 0.75 mm2) wire size.
