연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A two-part starter mechanism for a powder aerosol generator fire suppression system is provided. Generally, the starter mechanism includes a pyrotechnic igniter assembly and a removable mechanical trigger coupled thereto. The igniter assembly is integrally formed with and/or embedded within the powder aerosol generator and operable, upon activation by the mechanical trigger, initiates a chemical reaction leading to the discharge of the powder aerosol fire suppressant. By being detachable, the mechanical trigger may be transported and stored separate from...

1. In a fire suppression system comprising a housing containing a quantity of a chemical oxidizing compound which upon ignition of the compound is capable of generating a powder aerosol discharge, the system further comprising a pyrotechnic igniter assembly for igniting the chemical oxidizing compound, wherein the system comprises the improvement of: a removable mechanical trigger comprising a trigger body inside of which is located a spring-loaded firing pin, and an actuator assembly that is releasably coupled with said firing pin, at least a portion of said actuator assembly in its un-actuated state being slidably received within said trigger body;said mechanical trigger being coupled with the igniter assembly, wherein said actuator assembly upon actuation causes said firing pin to shift away from said igniter assembly thereby compressing said firing pin spring until said actuator assembly disengages from said firing pin and initiates a firing sequence within the igniter assembly resulting in ignition of the output charge, said igniter assembly comprising a primer, a delay, and an output charge, and wherein ignition of said chemical oxidizing compound by said igniter assembly initiates an aerosol-producing chemical reaction thereby expelling said powder aerosol discharge from said housing. 2. The fire suppression system according to claim 1, wherein said mechanical trigger is threadably secured to the igniter assembly. 3. The fire suppression system according to claim 1, wherein the actuator assembly comprises a handle. 4. The fire suppression system according to claim 1, wherein said mechanical trigger comprises a removable safety pin that inhibits shifting of said actuator assembly and firing pin. 5. The fire suppression system according to claim 1, wherein said igniter assembly comprises an igniter body defining an igniter bore, said primer, delay and output charge being located within an inboard portion of said bore, at least a portion of said trigger body being received within an outboard portion of said bore. 6. The fire suppression system according to claim 5, wherein the portion of said trigger body received within said outboard portion of said bore includes said firing pin. 7. The fire suppression system according to claim 5, wherein the portion of said trigger body received within said outboard portion of said bore includes at least a portion of the spring associated with said spring-loaded firing pin. 8. The fire suppression system according to claim 1, wherein upon disengaging from the actuator assembly, the firing pin shifts toward and contacts a portion of the igniter assembly thereby initiating said igniter assembly firing sequence. 9. The fire suppression system according to claim 1, wherein said chemical oxidizing compound comprises a potassium-containing compound selected from the group consisting of potassium perchlorate, potassium picrate, potassium benzoate, and potassium dinitrophenate. 10. The fire suppression system according to claim 1, wherein said aerosol-producing chemical reaction comprises gaseous and solid particulate reaction products, wherein said gaseous reaction product comprises a gas selected from the group consisting of nitrogen, carbon dioxide, water vapor, carbon monoxide, gaseous nitrogen compounds, and mixtures thereof. 11. A method of extinguishing a fire with a fire suppression system comprising a housing containing a quantity of a chemical oxidizing compound which upon ignition of the compound is capable of generating a powder aerosol discharge, the system further comprising a pyrotechnic igniter assembly for igniting the chemical oxidizing compound, said method comprising: attaching a mechanical trigger to said igniter assembly, said mechanical trigger being free of pyrotechnic material and configured for detachment and reattachment to said igniter assembly, said igniter assembly being permanently installed within said housing and comprising a primer, a delay, and an output charge;removing a safety pin from said mechanical trigger;actuating said mechanical trigger, said removing step and said actuating step occurring while holding a handle equipped to said housing,wherein said actuating step initiates a firing sequence within said igniter assembly resulting in ignition of said output charge, and wherein ignition of said chemical oxidizing compound by said igniter assembly initiates an aerosol-producing chemical reaction thereby expelling said powder aerosol discharge from said housing; anddeploying said fire suppression system into a fire environment prior to initiation of the chemical reaction resulting in aerosol discharge. 12. The method according to claim 11, wherein said mechanical trigger comprises a trigger body inside of which is located a spring-loaded firing pin, and an actuator assembly that is releasably coupled with said firing pin. 13. The method according to claim 12, wherein the actuator assembly comprises a handle, said method further comprising: pulling said actuator handle while also holding said handle equipped to said housing,wherein said pulling shifts said firing pin and actuator assembly from an initial position wherein a pair of latched segments reside in a narrow annular section within said trigger body to a second position wherein said pair of latched segments are located within a wider annular section formed in the remote end of said trigger body,wherein said shifting of said firing pin causes compression of a spring and creates a biasing force on said firing pin and said shifting causes said latched segments to become unlatched within said wider annular section, thereby causing said firing pin to shift toward said igniter assembly, strike said primer, and initiate said firing sequence. 14. The method according to claim 11, wherein prior to said attaching step, removing an end cap covering an outer portion of said igniter assembly.
