IntelliStripe 60, TTL Insertion Reader

In case of power failure, the capacitor automatically opens the latch, which releases the card.
The users must specify wire length required for their specific application. The power fail
capacitor range is 3300uF to 15000uF with a rated voltage greater than the applied motor
voltage. (The power-fail capacitor assembly is available as part number 21162301.)
POWER-FAIL LATCH RELEASE OPTION, L4
The power-fail unlatch option disengages the latch during a power failure. This option is
triggered when Vcc falls below 4.5 volts. An external backup capacitor is required for this
option to function. This capacitor is connected to the Reader as shown in Figure A-4. It should
be noted that with this option a separate motor voltage is not required.
