Sentx Infinity S - Office Building or Gated Res. Community Telephone Entry
System - 2-Line Display of 16 Ch. Each
Engineered for exceptional performances and functionality, the Infinity Series combines the convenience of telephone entry
with the flexibility of access control.

This powerful combination is designed with an extensive feature set and expandability to meet today's needs and
tomorrow's growth. Each control panel can support card and code access for 2 doors or gates. In addition, the Infinity has
the ability to network up to 16 panels for larger installation requirements.

The Infinity Series is perfect for securing any size office building or gated residential community. The LCDs utilize a high-
contrast ratio and bright backlight for clear viewing in a wide range of environmental conditions. Names and codes are
entered into the system through a handheld programmer or remotely with the optional SPSWin software.

INFINITY S EXCLUSIVE FEATURES
2-line LCD display of 16 characters each - 3/8" in height

STANDARD FEATURES
Full Duplex Communications
The system boasts audio that is crisp and clear in even the most congested environments by employing echo cancellation
technology. This technology prevents cross-talk between the speaker and the microphone and allows for higher volume
levels.
Long Distance and PBX Dialing
To allow for regions that utilize multiple area codes, Infinity systems accommodate sequences of up to 11 digits, as well as
PBX extension sequences of up to 6 digits.
Tone/Pulse Compatibility
Systems are configured on-site to operate on either type of available phone line.
Variable Code Length
Directory Codes and Entry Codes can be configured for individual site needs. Each Infinity can support from 1 to 4 digit
directory codes and 4 or 5 digit entry code lengths.
Battery Backup
Maintains clock and event record memory during power outages.
Burglar Alarm Shunt
When access requests are authorized, the system triggers a relay, which is in turn wired directly to the externally monitored
alarm panel preventing false alarm conditions.
Programmed Talk Time
Talk time can be adjusted from 15 to 250 seconds to accommodate various entrance requirements.
Shared Phone Line Capability
Up to 2 Infinity units can be linked to a single phone line, saving building management the cost of additional phone line
charges. Only one unit will control the shared phone line at a time.
Controlled and Programmable
System Relays This feature allows simultaneous control of the main gate and an auxiliary connection such as a second
gate or door. Relays can be managed remotely from a touch-tone phone and can be latched in an open or closed position.
The relays can also be controlled to activate for a set amount of time from 1 to 63 seconds.
Internal Modem
An internal modem allows convenient system programming and management access with SPSWin from a remote office
location.
Lightning Protection
Infinity systems have some protection on the power and telephone line connections. However, external surge suppressors
are recommended in areas prone to harsh weather conditions.
Non-Volatile Memory
All database information is maintained in non-volatile memory ensuring system functionality when power is disrupted.
Transaction Monitoring
The Infinity system is designed with an RS-232 printer port to print out real-time transactions allowing office or guard
personnel the ability to keep track of on-site activities.
Password Protection
Each Infinity can be customized with a 6-digit numerical password to ensure the security of database information.
Forced Door Alarms
If an entrance monitored by an Infinity is forced open, an alarm condition will display at the SPSWin software screen to
notify you of the event information.
Automatic Unlock Schedules
Automatic unlock schedules allow you to leave certain entrances open during business hours allowing freedom of
movement for vehicles, employees, and customers.

OPTIONS
Anti-Glare
In areas exposed to substantial sunlight, an anti-glare package can be installed to prevent direct exposure to the display,
thus reducing glare.
Stainless Steel Housing
All “S”, “M”, “L” and “DI” units include stainless steel faceplates as standard to ensure long-lasting durability. To increase
the resistance to vandalism and environmental conditions, these systems can also be ordered with a stainless steel
housing.
Multi-Link
A multi-link chain of up to 16 Infinity panels can be networked together for ease of programming. All panels communicate
through the first unit in the chain.
Full Controls
For scenarios that require highly tailored access specifications, this feature allows the system manager full control of all
access options on the Infinity system.
CCTV camera
The Infinity L and M are capable of hosting a black-andwhite or color camera that provides live video directly to a television
or monitor screen.
Commercial Building Directory
Office building installations may require the Infinity L commercial firmware, which supports 12 lines of tenant names and up
to 35 characters each.
Postal Lock Provision Infinity units support a switch kit that integrates with a U.S. Postal Service Lock. This allows postal
carriers entry to a controlled area using a U.S. Postal Service Key. The postal lock is proprietary to the U.S. Postal Service
and is acquired through them.
Handset A handset is recommended for sites requiring more privacy or located in a noisy environment. Available for all
Infinity “M”, “L” and “DI” models.
No-Phone-Bill Interface All Infinity units can operate independent of an outside telephone line, minimizing operating costs
and allowing system use by tenants without phone service.
