C-1000B Door Entry Controller
The C-1000B allows single line phones or phone systems to share a phone
line with one or two doorboxes or paging amplifiers. The C-1000B provides
two Touch Tone controlled relays to operate door strikes or gate openers and
provides doorbox triggered CCTV camera switching.
Doorboxes and paging amplifiers can now be used on single line, residential
or home office applications as well as on fully loaded systems, because they
are no longer limited to installation on unused trunk ports. The C-1000B
expands the potential installation sites for many peripherals such as door-
boxes and paging amplifiers. For more information, see DOD# 155.

SRC-1 Secure Relay Controller
The SRC-1 enables a standard touch tone phone to securely operate a set
of timed relay contacts to control a doorstrike or gate controller at a remote
location. The SRC-1 is fully user programmable and uses non-volatile mem-
ory. The SRC-1 eliminates the possibility of dialing the activation code
through the entry phone using a hand held touch tone dialer.
The SRC-1 is installed between the entry phone and the secure phone, and
will reject touch tones from the entry phone and only operate the relay if the
correct activation code (user programmable) is given from the secure phone.
The SRC-1 also provides up to 32 keyless entry codes to operate the relay
from the entry phone with 1 to 6 digits. This feature can be disabled in pro-
gramming for increased security. For more information, see DOD# 409.
LDB-3 Advanced Ring/Loop Detector
The LDB-3 Advanced Loop Detector monitors an analog phone line for ringing and/or an
off hook condition. A built-in relay can be activated when either of these conditions are
detected. This is ideal for monitoring line status or for providing a visual indication of such.
The LDB-3 can be used with any W-Series doorbox to provide a dry contact closure when
the button is pressed on the doorbox and can be maintained while communicating with
the doorbox if desired. This contact closure can be used to trigger a security camera or
activate a doorbell system. The LDB-3 comes complete with a 12 VDC power adapter,
and can also provide switched 12VDC .35 Amp output to power external lights, etc. dur-
ing ringing and/or off-hook conditions. For more information, see DOD# 409.
In the idle state, the W-3000 provides 24V DC talk battery. The LED remains lit for night time visibility.
When the “Call” button is pressed, the W-3000 generates a standard or custom (double) ring cadence
(adjustable from 2-30 rings). The LED will turn off and then begin flashing during ringing. When the call is
answered, ringing will stop and the LED will light steady. When the called party hangs up, the LED will turn off
momentarily and then remain lit for the idle state.
