Keyless Entry - Viking C-3000 Product Manual

B. Allowing a Visitor Entry
After communicating with a visitor at the door, the tenant can allow the visitor access to the building by entering
a programmable code on the tenant's touch-tone telephone. The factory default relay activation code is "6". Upon
entering this code, both parties will hear a brief buzzing tone as they are disconnected from the telephones, and
the door strike relay operates giving the visitor access to the building. If the tenant had a call in progress, the
tenant will also be automatically returned to the original call. If the visitor attempts to enter the relay entry code
themselves, the C-3000 system detects this and automatically disconnects both parties, without activating the
doorstrike relay.
C. Keyless Entry
Each tenant can be assigned a unique four to six-digit entry code, which may be used to gain access to the
building without their key. In addition to the 96 tenant Keyless Entry codes, there is also one additional "Primary"
keyless entry code. To access the Keyless Entry feature, the tenant takes an entry phone off-hook and enters "#",
plus their keyless entry code. The doorstrike relay will then operate to allow the tenant access to the building.
Note that it is not a requirement to set or use the C-3000 keyless entry feature.
D. Changing Keyless Entry Codes or Programming Features
From the Building Manager's Phone or the "Program Phone" port, all programming, including codes, can be per-
formed. To change a keyless entry code, the Building Manager picks up the Building Manager's Programming
phone, (if both entry phones are idle, two beeps will be heard to confirm that the C-3000 system is ready for pro-
gramming) and dials: (New 4-6 digit entry code) + "#" + (00-96)
For example, to set the Keyless Entry code for apartment 24 to "052069", the Building Manager would enter
"052069#24" and then hang up, unless additional codes need to be changed. Two more beeps from the Building
Manager's programming phone confirm a valid entry, three beeps will signify an error. See the "Programming"
section for full details on the procedure for changing keyless entry codes. Note: Both entry phones are disabled
during programming.
E. Postal Lock Feature (Authorized Persons Only)
This feature is provided to allow an authorized person, such as a Postal Service worker to gain access to the
building using a special key lock switch dedicated to this purpose. Keying the Postal Lock (momentary contact
closure) will activate door strike 1 contacts for about 5 seconds.
Symptom 1:
The entry phone is able to call a secondary apartment, but when they attempt to dial the relay command ("6" by de-
fault), the door/gate doesn't open (the doorstrike contacts of the primary C-3000 don't operate). When calling a primary
apartment and dialing the relay command, the door/gate does open. Also, the doorstrike contacts of the secondary
C-3000 are activating when the entry phone calls a secondary apartment and the party dials the relay command (the
secondary C-3000's relay would not activate in a working primary/secondary configuration).
Probable Cause and Solution:
Check the "multi-module interconnect" modular cord between the primary and secondary (or in larger "stacks", the
cord between the first secondary C-3000 with the problem and the secondary C-3000 ahead of it in the stack). If the
cord is only a two conductor modular cord, it must be replaced with a four conductor modular cord. If it is a four con-
ductor modular cord, the cord has an open in the second pair (yellow or black wires) and should be replaced (the po-
larity of this modular cord must be correct - see Probable Cause and Solution for symptom 2).
Symptom 2:
As soon as the "multi-module interconnect" modular cord is connected from the "in" of the primary C-3000 to the "out"
of the secondary C-3000, the "in-use" LED's light up steady on both C-3000's.
Probable Cause and Solution:
The modular cord being used to connect the C-3000's together is the wrong polarity. The modular cord must be a
standard "straight through" modular cord, rather than a "reversed" modular cord. The modular cord supplied with the
C-3000 is the correct polarity. Either use the supplied modular cord, or make sure the locking tab is on the same side
of the modular cord at both ends, if making your own modular cords.
Symptom 3:
Everything works properly when the entry phone calls an apartment on the primary C-3000. When the entry phone
tries to call a secondary apartment, the entry phone receives both ringback tones and a busy signal (at the same
time), as the call is ringing through to the secondary apartment.
Probable Cause and Solution:
The primary C-3000 has not been properly programmed with the "number of modules" in the stack (##8 memory lo-
cation). The primary C-3000 must be told how many C-3000's are in the stack and this is set to one by default. Pro-
gram the primary with the correct number of units in the stack. See Programming, Section C (Primary Module
Setup) for programming details.
