GSA-WTM

Overview
The GSA-MM1 Monitor Module and GSA-WTM Waterflow/Tamper Module are part of Kidde’s Signature Series system. 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). 
The function of the GSA-MM1 and GSA-WTM is determined by the factory loaded “personality code”. The input modules gather analog information from the initiating devices connected to them and convert it into digital signals. The module’s on-board microprocessor analyzes the signal and decides whether or not to input an alarm. 
The microprocessor in each module provides four additional benefits - Self-diagnostics and History Log, Automatic Device Mapping, Stand-alone Operation and Fast, Stable Communication.

Standard Features
 • Monitor and waterflow/tamper applications 
Includes Alarm with delayed latching (retard) for waterflow  
applications, Supervisory, and Monitor.  
• Non-volatile memory 
Permanently stores serial number, type of device, and job  
number. Automatically updates historic information including 
hours of operation, last maintenance date, number of alarms 
and troubles, and time and date of last alarm. 
• Automatic device mapping 
Each module transmits wiring information to the loop  
controller regarding its location with respect to other  
devices on the circuit.
 • Electronic addressing 
Permanently stores programmable address; there are no  
switches or dials to set. Addresses are downloaded from  
a PC, or the SIGA-PRO Signature Program/Service Tool.
 • Intelligent module c/w integral microprocessor 
All decisions are made at the module allowing lower  
communication speed while substantially improving control  
panel response time. Less sensitive to line noise and circuit 
wiring properties; twisted or shielded wire is not required.
 • Ground fault detection by address 
Detects ground faults right down to the device level.
 • Designed for high ambient temperature operation 
Install in ambient temperatures up to 120oF (49oC).
