Access Control Cheat Sheet
Wiegand Wiring Typical:
**Shield should only be terminated on one end of the cable, usually at the panel, just twist around the jacket at the card reader**
OSDP Wiring:
**NOTE 120Ohm resistor at reader between Tan/Red With Green Stripe**
Door Contacts
Wired Normally Closed and Wired in series as shown below:
Request to Exit (REX)
• Typically Wired Normally Open regardless of the type of rex used (integrated rex in handle/crash bar, motion sensor rex PIR above door etc) • Wire Colors and DIP Switches vary depending on model so they will not be displayed here • For MagLocks the power should pass directly through the REX device in series to be fully code compliant, though very rarely does this happen. Most Motion detectors have 2 relays, one should be the signal to the panel and the other should be the power cut relay. • BOSCH DS160 dip switch settings: 12357 on, all others off.Device Location Measurements
• Card Reader – 42-48 inches above finished floor • Key Switch – 42-48 inches above finished floor • Push-To-Exit – 42-48 inches above finished floor • Door Contacts – 4-6 inches in from edge of doorTypical Door Layout
**NOTE REX Device is on Secured Side of door and Card Reader is on Unsecured side of door**
