SECTION 1:
INTRODUCTION
The Alto 818 access control units, SE 818SC and SE 818SX, are central processing devices for
access control and alarm monitoring systems manufactured by Westinghouse Security Electronics
(WSE). These systems comprise the ACU and associated hardware, either manufactured or
supplied by WSE, required to configure an access control and monitoring installation of up to eight
doors.
 The SE 818SC and SE 818SX are listed by Underwriters Laboratories and meet Access Control
Standard ANSI/UL 294 when installed according to the instructions in this manual.
 All system installation wiring must be in accordance with the National Electrical Code ANSI/
NFPA70.
 The SE 818SC and SE 818SX are not intended to be used as a burglar or fire alarm system and
shall not be used where the local authority having jurisdiction requires a UL-Listed burglar alarm
system.
The purpose of this manual is to provide the information for installing and using the SE 818SC and
SE 818SX. This includes developing an installation plan and installing all hardware items.
Database setup and system operation are discussed in Sections 7 and 8.
Each installation plan is tailored to the particular requirements of the building or area the system
is designed to protect taking into account the capabilities of the hardware items available to
implement these requirements. Consequently, the type and quantity of system hardware items
required for a specific application cannot be specified here. This manual is limited to descriptions
of the hardware items available for all applications, instructions for developing an installation plan,
and guidelines for proper installation.
This manual is written for installations in which the ACU is functioning as a stand-alone access
control system, S-mode (see Section 1.2.2). Installations in which the ACU is reporting to and
controlled by a security management system such as the SE 5850 or the SE 6000, E-mode, are
covered in detail in the SE 5850 and SE 6000 technical manuals.
The information provided in this manual is not intended to conflict with the specific building codes,
electrical codes, fire codes, or safety codes to which any given system design must conform.
