Warranty Information
Manufacturer warrants products for 36 months from the date of manufacture against defects in material and workmanship.
The GFPS-9 is a notification appliance circuit and auxiliary power expander providing up to 9 amps of 24-volt power. It connects to fire alarm control panels to power notification appliances and auxiliary devices. It features two optically isolated signaling inputs, four power-limited notification appliance circuits (configurable as Class A/B), and a dedicated auxiliary output. It also includes a Form C trouble relay and earth fault detection. The GFPS-9 supports synchronized appliances and ANSI temporal-coded outputs, simplifying installation by eliminating the need for separate synchronization modules.
