GSA-REL Technical Reference Manual 7
Power supplies
The GSA-REL is compatible with the following power supplies:
• 2-PPS, 2-PPS/220
• 2-PPS/6A, 2-PPS/6A-220
• MIR-BPS6A*, MIR-BPS6A/230*
• MIR-BPS10A*, MIR-BPS10A/230*
* Not compatible with FM sprinkler applications that require 90 hours of standby.
Note: The GSA-REL is not compatible with the QuickStart power supply
(PS6 - Power Supply Card).
Notification appliances
The GSA-REL prerelease circuits support audible and visible notification
appliances. You must use appliances that are compatible with the fire alarm
control panel. Refer to the control panel documentation for a list of compatible
appliances.
Note that the GSA-REL is not designed to generate an NFPA 72 standard alarm
evacuation signal, and does not meet UL 864 requirements for an audible alarm
notification circuit intended for evacuation.
Solenoid control relays
To activate the releasing solenoids, you must use RELA-EOL relays as solenoid
control relays. These relays buffer the GSA-REL from valve solenoid spikes. For
more information, see the RELA-EOL installation sheet.
Manual release stations
For manual release stations, the GSA-REL requires normally-open, dry contact
signal initiating devices. The manual release station controls only the GSA-REL
to which it is connected.
Manual release stations must be listed with the appropriate agencies in your
area. See the heading “Listing agencies” on page 9.
The following manual release stations are approved by FM for use with the
GSA-REL:
• M276A-REL - Manual Release Station
• M278A-REL - Double Action Manual Release Station
