GSA-UM

Overview

GSA-UM Patented GSA-MAB The GSA-UM and GSA-MAB are Universal Class A/B Modules. They are intelligent analog Addressable devices that are part of Kidde’s Signature Series system. The actual function of the module is determined by the “personality code” selected by the installer. This is downloaded to the module from the Signature loop controller during system configuration. The GSA-UM and GSA-MAB gather analog information from the slave devices con nected to them and convert this into digital signals. Each module’s on-board microprocessor measures and analyzes the signal and decides whether or not to input an alarm.

The GSA-UM is installed to a standard North American 2-gang 
electrical box, making it ideal for locations where only one module 
is required. Separate I/O and data loop connections are made to 
each module. The GSA-UM may be used to connect any one of 
the following:
 • two Class B or one Class A Initiating Device Circuits
 • one Class A or B Notification Appliance Circuit
 • one Class A or B Circuit for 2-wire Smoke Detectors
 • one Form “C” (NO/NC) Dry Output Contact Relay

Standard Features
• 15 modules in one 
Multiple applications including Class A or B device circuit wiring, Class 
A or B 2-wire smoke detector circuits and delayed latching (retard) 
for waterflow alarm applications. The installer selects one of up to 15 
“personality codes” to be downloaded from the loop controller.
• Plug in (UIO) or standard 2-gang mount 
UIO versions allow quick installation where multiple modules are 
required. The 2-gang mount version is ideal for remote locations that 
require a single module.
• Automatic device mapping 
Signature modules transmit information to the loop controller regarding 
their circuit locations with respect to other Signature devices on the 
wire loop.
• Electronic addressing 
Programmable addresses are downloaded from the loop controller, a 
PC, or the SIGA-PRO Signature Program/Service Tool. There are no 
switches or dials to set. 
• Intelligent device with microprocessor 
 All decisions are made at the module to allow lower communication 
speed with substantially improved control panel response time and less 
sensitivity to line noise and loop wiring properties; twisted or shielded 
wire is not required.
• Non-volatile memory 
Permanently stores serial number, type of device, and job number. 
Automatically updates historic information including hours of operation, 
last maintenanc  e date, number of alarms and troubles, and time and 
date of last alarm. 
• Stand-alone operation 
The module makes decisions and inputs an alarm from initiating 
devices connected to it even if the loop controller’s polling interrogation 
stops. Function availability dependant upon control panel.
 • Ground fault detection by address 
Detects ground faults right down to the device level.
 • High ambient temperature operation 
Install in ambient temperatures up to 120oF (49oC).
 • Designed to ISO 9001 standards 
All Signature products are manufactured to strict international quality 
standards to ensure highest reliability.
