Access Control System - 818

General Information

The Alto 818 is an advanced access control unit that can easily manage the
security of both small and large applications. Combined with a host system
from NexWatch, the Alto 818 provides virtually unlimited access control

Maximum control
A complete proximity access control and alarm monitoring system, the Alto
818 controls up to 8 entrances, monitors up to 32 input points, allows up to
11,200 individually numbered command keys, facilitates up to 120 unique
access codes, and stores up to 4,000 event logs.
The Access Control Unit (ACU) monitors and controls up to eight Multiple
Switch Monitors (SE774A), each monitoring four input points. Power supply
options include a power module developed exclusively for the Alto 818
(SE3018), or one with battery backup capability that provides continuing
operation if power fails (SE3718S). An eight-point annunciator device (SE778A)
is also available for additional relay output or building mode control. Adding to
their system flexibility, Alto 818 controllers support multiple access control
and reader technologies. The Alto 818SX supports analog proximity sensors
and keypads, plus compact, medium-range, standard, non-incendive and
intrinsically safe sensors. The 818SC, in addition to the features of the 818SX
also adds support for DigiReader and smart card readers. Though the
818SC does not support medium-range analog sensors, its ability to support
digital technologies gives the 818SC a read range from four to 20 inches*
when used with the NexWatch DigiReader family of digital readers.

Fully networkable
The Alto 818 is fully functional as a stand-alone system, or it can be linked
with multiple units from a central location using either an SE5850, NexSentry
Manager*, NexSentry Command Center, or NexSentry StarGaze host. The
SE5850 can accommodate up to 32 directly connected units; both the NSM*,
NSCC and StarGaze can manage thousands of ACUs for even the largest
