Diode Selection: Diode current rating: 1x strike current. Diode breakdown voltage 4x strike voltage.For 12 VDC or 24 VDC strike, diode 1N4002 (100V/1A) typical.TB10 or TB11NC C NONC C NOMOV Selection: Clamp voltage: 1.5x VAC RMS. For 24 VAC strike, Panasonic ERZC07DK470 typical.29.5.1Power and Alarm InputsThe LNL-2220 requires 12-24 VDC power. Locate power source as close to the unit as possible. Connect power with minimum of 18 AWG wire.Note:Connect the GND signal to earth ground in ONE LOCATION within the system! Multiple earth ground connections may cause ground loop problems and is not advised.Observe POLARITY on 12-24 VDC input!There are two dedicated inputs for cabinet tamper and UPS fault monitoring. Normal (safe) condition is a closed contact. If these inputs are not used, install a jumper wire.150 — revision 6Hardware Installation Guide
