SECTION 4: WIRING
This section provides the product information necessary to install an Alto 818 access control
system. Because each installation site is unique, only general guidelines for an installation plan

which may be included in the security system. Connectors, pin-outs and wiring connections are
given.
All installation wiring shall be in accordance with the National Electrical Code ANSI/NFPA70.
Installation according to this manual will meet specifications for a UL 294 access control system.
A UL 294 access control system must be tested annually as described in Section 9.
