TeleFire can be powered by any +10-15V supply, from 3-cell lithium polymer packs used in RC aircraft +to a 12V lead acid battery. + + * Continuity Detection. Igniter continuity uses a low-current sensing + system which sends only 100µA through the igniter to prevent false + ignition.

TeleFire has two 12V medium current (5A) outputs + to drive a siren and strobe light when the launch system is armed + and ready to fire. + + * Local arming switch.
