Troubleshooting - Control 4 C4-DSC-EN-BL Setup Manual

Connecting contacts and relays
You can connect devices to the contact ports or the relay ports
(see Figure 13).
Figure 13: Contacts and relays
Contacts
Caution! Control4 does not support using earth ground
for contacts, because this can damage the Door Station.
Connecting to a terminal
The Door Station provides nine connections for contacts and
relays: three terminals for Contact 1, three terminals for Contact 2,
and three terminals for the relay (see Figure 14).
• Contact (2 sets)—Terminal connector for one dry contact
closure, logic input connection, for gate control, etc.
Provides power for small devices (12 V), signal input (SIG),
and return path (GND). The current, 100mA, is shared across
both sets of contacts.
Note: Do not use contacts that are grounded. The Door
Station only supports non-grounded contacts.
• Relay (1)—Terminal connector for one normally closed or
normally opened switchable connection for doorbell control
(see Figure 15) or gate control. The set contains a connection
for Normally Opened (NO), Normally Closed (NC), and
Common (COM).

To attach the wires to the contacts or relay:
1 Select one of the large bottom-row holes (see Figure 13).
Notice that the top-row holes are smaller than the bottom-
row holes).
2 Using a small, flat-blade screwdriver, insert the screwdriver
into the slot on the small block that sits between the two
rows of holes next to the port, then push down firmly. The
block will depress.
3 Insert the wire. Make sure that the wire inserts all the way
into the hole.
4 Release the screwdriver.

Troubleshooting

Boot up
When the Door Station is booting up, if the button blinks and
does not stop after three minutes, the Door Station will need to
be restored to factory settings. See "Resetting/Factory restoring
the Door Station" earlier in this document.
Restoring to factory settings
To restore the device to its default factory settings, see
"Resetting/Factory restoring the Door Station" earlie in this
document.
Security best practices
The Exterior Door Station is the first smart Control4 device
designed to be installed on the outside of a dwelling. The Door
Station has connections for relays (to open doors and gates) and
contacts. If installed without the proper security precautions,
unauthorized access to the Door Station could provide access
to Ethernet signals, Control4 signaling, and gate or door relays.
Control4 advises Control4 Dealers to be aware of these risks
and take all necessary precautions depending on each specific
installation you will be doing.
• It is each dealer's sole responsibility to advise their customer
at each installation of any security risks specific to such
installation. Control4 makes no claims, representations,
or warranties regarding the security of this product and
accepts no liability for any security risk attendant to a
specific installation.
• The Exterior Door Station ships standard with security
screws. Dealers are encouraged to use these screws, or
even substitute alternate security screws per the dealer's or
customer's preference. Screw size is metric M3.5x.6-30L.
• Security gates or automatic doors should not be connected
to the relay in the Door Station if mounted in an unsecured
area. Such relays could be accessed in the event of a
breach of the device. Secure, relay-driven devices should be
connected to a more secure relay controller mounted behind
a secure wall.
• Security devices, for example, numeric keypads, should not
be connected to the contact sensors in the Door Station
if mounted in an unsecured area. Such devices could be
accessed in the event of a breach of the device. Security-
sensitive devices should be connected to more secure
contacts mounted behind a secure wall.
