Zusammenfassung:	A fire extinguisher actuator assembly (200; 200A) for a fire extinguisher (102) is provided. The fire extinguisher (102) includes a fire extinguisher reservoir (106) and a burst disc (108) that forms a discharge barrier between the fire extinguisher reservoir (106) and a discharge head (104) to retain a pressurized fire extinguishing agent (212) within the fire extinguisher reservoir (106). The fire extinguisher actuator assembly (200; 200A) includes a cutter shuttle assembly (202; 202A) having a cutter (204) coupled to a shuttle body (206; 206A). The cutter shuttle assembly (200; 200A) is detained within the fire extinguisher (102) proximate the burst disc (108) and biased to form a pressure equalization region (218) between the shuttle body (206; 206A) and the burst disc (108). The fire extinguisher actuator assembly (200; 200A) also includes an activation device (220; 220A) having a piercing member (222; 222A) operable to pierce the burst disc (108) and release pressure from the pressure equalization region (218), thereby driving the cutter (204) through the burst disc (108) to release the pressurized fire extinguishing agent (212) through the discharge head (104).
