GSA-MM1
Monitor Module
The GSA-MM1 is a single-circuit intelligent module that includes a Class B normally-open dry contact. This is used for monitoring input from devices such as fans, dampers, and doors. When the input contact is closed, an “active” signal is sent to the loop controller. The active condition is not latched at the module.
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).
