The Crown Jewel is the most advanced telephone entry system
for securing gated residential entrances. Its elegant design
and extensive features allow any residence to increase the
level of security while enhancing the value of the home.
With budget constraints always an issue, Sentex designed
a host of features in every model at one low cost making
it the perfect solution.
The Crown Jewel is a small, non-obtrusive, self-contained
unit that connects directly to your existing phone line,
known as a No Phone Bill System. Since the connection is
made to your existing phone system, it does not require
any additional monthly phone charges.
Family members, delivery persons, or friends can be issued
a unique 4-digit access code that is used to enter the gated
entrance without having to initiate a call sequence. When
visitors are not welcome, such as 6:00 PM to 8:00 AM, a
time schedule can be assigned that prevents access automatically.
Additionally, all calls can be suppressed by enabling a
manual or time based Do Not Disturb feature. This prohibits
a person from driving up to the entrance in the early morning
hours and ringing the phone.
For an extra level of security, you may choose to view
the person requesting access at the gate. The Crown Jewel
supports a built-in CCTV camera that displays live video
direct to your television or monitor. The system also maintains
the last 250 actions and programming entries stamped with
the date and time of the event for reviewing historical
There are several ways of programming a Crown Jewel. If
a computer is available you can use the intuitive Windows
95/98 based software tool for retrieving, sorting, and programming
the unit. If a computer is not available, the Crown Jewel
can be programmed using a standard touch-tone phone or the
Crown Jewel keypad. Whichever method you select, guided
prompts ensure programming time is kept to a minimum.
The Crown Jewel is available in several attractive styles
to match the taste of the homeowner. They are engineered
to withstand harsh weather conditions and typical vandalism.
Whether installing on a pedestal or flushed into a custom
stand, the Crown Jewel’s lighted keypad and bright
letters make it simple for anyone to view and operate.
Up to 75 unique 4-digit access codes can be
assigned to unlock the gate or door without needing to call
the resident. In addition, all codes can be used to latch
the gate or door open. All transactions are logged for future
Provides a unique double ring on the resident’s telephone
to distinguish between a standard call and gated entrance
Allows the resident to answer a call from the gate while
in the middle of another outside call. Similarly, if a call
is in progress to the gate and an outside call rings, the
resident can switch over to take the call and return back
to the original gate call.
Allows the Crown Jewel to dial a pre-programmed telephone
number when the resident is not at home. The resident can
then grant or deny entrance from that remote location (This
can be a manual or time activated function.)
Do Not Disturb
The homeowner can enable a period of time to not accept
any calls from the Crown Jewel. This can be accomplished
manually through a touch tone phone or via a pre-planned
time schedule, such as 7:00 PM to 9:00 AM.
Gate/Door Unlock Scheduling
The main or auxiliary gate can be configured to automatically
open twice per day for a pre-defined time scheduling.
Up to 10 holidays can be defined to prevent automatic unlock
Controllable System Relays
Allows the main gate and an auxiliary connection (a second
gate or door) to be controlled, such as opened to let a
visitor enter. The relays can be remotely managed from the
manager’s or any remote touch-tone phone. Once connected,
the relays can be latched open permanently or pulsed from
1 to 99 seconds.
Each system can be site configured to operate on the two
types of available phone lines.
If one of the gates or doors is forced open or held open
too long, the Crown Jewel can automatically be triggered
to phone the residence or a telephone number defined. An
alarm can also be initiated if a visitor attempts too many
incorrect access code attempts.
Multiple Call Locations
Allows the visitor to place a call to up to three telephone
numbers other than the main residence. If the calls are
directed to an outside line, telephone charge may apply.
The Crown Jewel supports up to an 11 digit dialing sequence.
Multiple Gate Entrances
The Crown Jewel can be networked with up to 6 other Crown
Jewels on a single telephone line when multiple entrances
are required. Each unit is connected to its own bypass board.
Only the "calling" system location gate opens
when access is granted.
Provides the ability to program the system via a personal
computer from a remote location.
Physical inputs and telephone line connections contain
some protection against typical voltage spikes, such as
phone line variances and lightning. However, in an area
where lightning is prevalent, external surge suppressors
should also be used to minimize any power hits to the unit.
Battery Backed Clock/Calendar
The Crown Jewel is provided
with a 365-day clock for up-to-date time scheduling and
event recording. Leap Year is also automatically adjusted.
In the event power is removed from the unit, the database
information will be retained in memory allowing immediate
start-up and operation when power is restored.
