Push-Button, Key –Pad etc.
A variety of hard-wired input devices can be used to operate the LI-2B operator. Input
should be in the form of a MOMENTARY CLOSED CIRCUIT.
WARNING! Voltage must not be applied to these terminals. DAMAGE to the circuitry will
result if voltage is applied. Devices that send a Voltage Pulse (As some intercoms do) must
be connected to the circuit board through a relay.
Electric Lock
Connections for an electric lock/latch (EL) are provided on the circuit board. (See Figure 9)
This connection block will supply 12 Volts to energise the lock at the beginning of the
Opening and Closing cycles.
