Chapter 3: Programming
38 GSA-REL Technical Reference Manual
Programming the GSA-REL in the QS-CU
Minimum system requirements
• A QS1 with an SLIC card and appropriately sized standby batteries
• A compatible power supply with appropriately sized standby batteries to
supply 24 VDC to the GSA-REL
• The GSA-REL, mounted in an MFC-A enclosure
• A GSA-CT1 module to supervise the service disconnect switch
• A GSA-CT2 module to indicate activation of the prerelease and release relays
When you use monitor or supervisory event messages to indicate activation of
the service disconnect station, prerelease relay, or release relay, you must route
those messages to the panel.
Note: You cannot have more than 10 GSA-RELs on one SLIC loop.
Step 1: Read this first
WARNING: This information was prepared for users who are proficient in every
aspect of QS-CU programming. Do not attempt to program the GSA-REL without
a complete understanding of QS-CU and GSA-REL operation. Incorrect
programming may result in loss of life, serious injury, or property damage.
This application requires the operation of at least two automatic detectors to
activate the fire suppression system. In order to meet NFPA 72 requirements,
you must program an AND group with at least two smoke detectors and a
minimum activation count of 2. The smoke detectors must have their primary and
alternate verification properties set to None.
The GSA-REL has six addressable circuits. To add the GSA-REL to the loop
controller database, you must add three GSA-RELs. The first GSA-REL is for the
abort switch and manual release switch circuits, the second for the two release
circuits, and the third for the two prerelease circuits.
Using the QS-CU, perform the instructions that follow in order from beginning to
end.
As a safety precaution, disconnect releasing devices from GSA-REL TB4 before
downloading setup data to the loop controller.
The GSA-REL provides only one serial number label. When you scan in the
GSA-REL, only the first two serial numbers appear in the database.
