Setting DIP switches
Set the DIP switches on the 20DI board before installing it and wiring the alarm input devices. The 20DI PCB
board should be at Revision G or later. (The revision level can be found on the underside of the circuit board in
the lower right corner.)

To wire the digital input devices
1. Follow the installation specifications for the device. Mount the device according to the manufacturer’s
specifications. The alarm device (door contact) should have a dry contact which can have a Normally
Open or Normally Closed type switch. A Normally Closed contact is in its normal position when it is
closed. The opposite is true for a Normally Open contact.
2. Select the appropriate digital input for each alarm input device.
3. Ground the shields of the cable at the M3000 enclosure grounding studs. Float the shield (with tape or
shrink tubing) at the DI device end to avoid electrical noise.
4. Install two end-of-line resistors (not included). We recommend high quality, 1,000 (1K) ohm, 1/4 watt,
5% tolerance end-of-line resistors. Install each resistor as close to the door status contact as possible.
5. Insulate resistors with tape or heat shrink tubing.
6. Document how you wired the alarm input devices. Future expansion of the system and its maintenance
depend upon accurate documentation.
