BRASCH GSE2-CM-24 Factory Calibration Kit

Overview

Brasch Generation 2 sensor boards are calibrated at the factory and have an expected calibration duration of approximately two years. Environmental conditions may shorten or prolong this period of time, but once the sensor parameters drift outside of acceptable tolerances, the sensor board must be either be recalibrated or replaced.
This document outlines the procedure for installing a factory calibration kit of all Brasch Generation 2 sensor boards including:

Carbon Monoxide Models

GSE2-CM-24
GSE2-CM-120
GSE2-CM-Remote
TRNS2-CM-Analog
TRNS2-CM-Digital
GDCP-CM-Remote

Nitrogen Dioxide Models

GSE2-ND-24
GSE2-ND-120
GSE2-ND-Remote
TRNS2-ND-Analog
TRNS2-ND-Digital
GDCP-ND-Remote

Combination Models

GSE2-NCM-24
GSE2-NCM-120
GSE2-NCM-Remote
TRNS2-NCM-Analog
TRNS2-NCM-Digital
GDCP-NCM-Remote

Required

Phillips Screwdriver
Factory Calibration Kit
Pliers (Long or Needle Nose)

Procedure

Loosen the two lid screws and open the enclosure
Turn power OFF to the sensor board
Verify the Green Power LED is dark before proceeding
Remove all wire connections to the sensor board
Note the locations of these wires so they can be returned on the new board
Remove the retaining screws
For local sensors, there are three retaining screws (6-32 x 1/4”)
For remote sensors, there are four retaining screws (10-24 x 1/4”)
For local sensors only, pinch the locking standoff with a pair of pliers and gently lift on the closest corner of the sensor board
Extract the sensor board from the enclosure and set it aside
Make sure that all jumpers and switches on the new sensor board match those on the old sensor board
Place the new sensor board into the enclosure
Return the screws and tighten until the board is secure
Connect the wires to the sensor board in their original positions
Use the diagram on the following page for assistance
Turn power ON to the sensor board
Verify the Green Power LED is illuminated before proceeding
Close the lid and firmly tighten the two screws
Check for proper operation

Troubleshooting

If any of the following errors are present, press firmly on the sensor itself to ensure it is fully seated in the socket on the PCB.
- Standalone Detectors: 9996
- BMS Transmitters: 0x0004
- Control Panel Remotes: Sensor # Missing
If any of the following errors are present, check the wiring connections to the sensor board.
- Standalone Detectors: 960x
- BMS Transmitters: No Communication
- Control Panel Remotes: Sensor # Communication Loss
