CONTACT INPUTS.
The L7700 features two on-board independent closing contact inputs which may be configured for the
following operations:
APPLY EVENT – Create a call on the system, Call type, address and user may be
specified using the fields on screen.
RESET UNIT - Perform a hard reset to the L7700.
RESET SLOTS - Reset all incoming events on a bridged or distributed system
RESET OP1 For example an output can be used to activate a strobe or sounder, the
input can be configured to reset that output to act as a mute or reset button/key.
RESET NET. Reset all devices (Call Points, Displays etc) on the L7700 Output Network.
CONNECTING THE INPUTS
The inputs are simply closing contacts taken to 0V, there is a 10K pull up resistor to 3.3V on each contact
input. Do not apply voltage to these inputs, if connected to other systems they must be isolated using a relay
or similar.
