An actuator includes a housing with a first end, a second end opposite the first end, and a bore disposed therein. The bore defines a poppet movement axis and extends between the first end and second end of the housing. A solenoid is disposed within the bore and extends about the poppet movement axis. An armature is disposed within the bore and is movable along the poppet movement axis between a disengaged position and an engaged position, the engaged position proximate the solenoid and the disengaged position spaced apart from the solenoid. A magnet is disposed within the bore between the first end of the housing and the armature, the magnet magnetically coupled to the armature to bias the armature towards the disengaged position.

1. An actuator, comprising: a housing having a first end, a second end opposite the first end, and a bore defining a poppet movement axis extending between the first end and the second end of the housing;a solenoid disposed within the bore and extending about the poppet movement axis;an armature disposed within the bore and movable between an engaged position and a disengaged position, the engaged position being proximate the solenoid, the disengaged position being spaced apart from the solenoid;a magnet disposed within the bore between the armature first end of the housing, the magnet being magnetically coupled to the armature to bias the armature towards the armature disengaged position;a poppet movably disposed within the bore between a closed position and an open position, the open position being proximate the solenoid and the closed position being spaced apart from the solenoid;a collet disposed within the bore and longitudinally overlapping the poppet along the poppet movement axis, the collet being laterally movable between poppet-fixed position and a poppet-freed position;a locking ring disposed within the bore and longitudinally overlapping the collet, the locking ring being movable along the poppet movement axis between a locked position and an unlocked position; anda striker disposed within the bore between the locking ring and the armature, the striker axially overlapping both the armature and the locking ring to axially displace the locking ring and allow the poppet to move along the poppet movement axis. 2. The actuator as recited in claim 1, wherein the housing defines an armature stop disposed within the bore between the first end of the housing and the solenoid, the armature stop bounding the disengaged position of the armature. 3. The actuator as recited in claim 1, wherein the magnet is a first magnet and further comprising at least one second magnet, the second magnet being disposed on a side of the poppet movement axis laterally opposite the first magnet. 4. The actuator as recited in claim 1, wherein the magnet has an armed and a disarmed position, the disarmed position proximate the solenoid, the armed position spaced apart from the solenoid. 5. The actuator as recited in claim 1, further comprising a ferromagnetic body disposed within the bore between the first end of the housing and the magnet. 6. The actuator as recited in claim 1, wherein housing has a set bore extending axially from the first end of the housing to the bore, the magnet being movably disposed within the set bore. 7. The actuator as recited in claim 6, further comprising a magnet carrier threadably seated within the magnet bore and fixed to the magnet. 8. The actuator as recited in claim 1, wherein the magnet is coaxial with the poppet movement axis. 9. The actuator as recited in claim 1, further comprising further comprising a magnet carrier threadably seated within the magnet bore and fixed to the magnet. 10. The actuator as recited in claim 1, wherein the magnet is axially offset from the poppet movement axis. 11. A detection and suppression system, comprising: a pressure vessel containing a suppressant;a valve assembly having an actuator as recited in claim 8; anda controller communicative with a detector and operably connected to the actuator, the controller configured and adapted to energize the solenoid, displace the armature, and enable movement of the poppet to the open position such that the suppressant issues from the pressure vessel. 12. A valve assembly, comprising: a valve boss with an inlet, outlet, and an actuator seat;an actuator as recited in claim 1 fixed to the actuator seat of the valve boss; anda poppet movably disposed within the bore of the actuator between a closed position and an open position, the open position of the poppet being proximate the solenoid, the closed position being spaced apart from the solenoid,wherein the armature is operably connected to the poppet such that (a) the inlet is fluidly isolated from the outlet when the armature is in the disengaged positon, and (b) the inlet is in fluid communication with the outlet when the armature is in the engaged position. 13. The valve assembly as recited in claim 12, wherein the magnet has an armed and a disarmed position, the disarmed position proximate the solenoid, the armed position spaced apart from the solenoid. 14. The valve assembly as recited in claim 12, further comprising a ferromagnetic body disposed within the bore between the first end of the housing and the magnet. 15. The valve assembly as recited in claim 12, wherein housing has a set bore extending axially from the first end of the housing to the bore, the magnet being movably disposed within the set bore. 16. The valve assembly as recited in claim 15, further comprising a magnet carrier threadably seated within the magnet bore and fixed to the magnet.
