• Reader power: 12 VDC output, fused at 2 A per reader; combine load should not exceed module’s rated DC output.
• Lock output: Relay rated for switching up to specified voltage/current; for high inrush locks use a dedicated power supply sized for inrush plus steady state.
• Supervised inputs: Use 4.7k end-of-line resistor (example) if module requires; confirm exact resistor value from UPD or manual.

1. Voltage check – Input 12-24 VDC. Reader output set to match reader spec (5V or 12V).
2. DIP switch S1 – New table for address setting. S1-8 now controls “Auto-negotiate OSDP” (default = OFF).
3. Jumper J3 – Determines RS-485 termination. The UPD manual says only enable if module is last on the bus (previously ambiguous).
4. Grounding – The M5 requires a chassis ground to the can/backbox. Skipping this leads to intermittent tamper faults.

1. Read the manual carefully: Before starting the installation, make sure you have read and understood the entire manual to avoid any mistakes or oversights.
2. Follow local codes and regulations: Ensure that the installation complies with local building codes, fire safety regulations, and electrical codes.
3. Qualified personnel only: The installation should only be performed by qualified and authorized personnel.
