The DM02 Door Station Module provides the functions of Comfort’s Door

Station, but using a third party audio or video Intercom system like the

Fermax CityMax and Cityline series, Farfisa, or the DP04 Door Station.

Instead of having the DP03 Door Station at the door or gate, the third

party Intercom outdoor call station or DP04 will be used. The DM02

module is mounted within or next to the main Comfort control panel.

When a visitor presses the doorbell on the intercom call station, the

Intercom Indoor handsets will ring, as well as the internal telephones

connected to Comfort Either the intercom handset or the internal

telephones can be used to talk to the visitor and open the door or gate.

The DM02 provides two relay outputs to operate 2 doors or gates. When

the security system is armed, Comfort will dial to the programmed

telephone number to allow the user to talk to the visitor and to open the

door or gate as well as disarm the security system if the guest is

welcome. This extends the utility of a normal audio/video intercom

system.

Jumper Settings

wJ1: Shunt J1 to positions 1-2 if the doorbell input (to BELL

terminal) is a DC signal of 5V to 24 VDC. Leave J1 open if the

Doorbell input is an AC signal 5 V to 24 VAC. Shunt J1 to positions

2-3 if the doorbell input is a voltage free contact. Default shunt.

Comfort DM02 Door Station Interface

wJ2 - Tone: Shunt for louder Beep tone volume. This affects

specific Door station beeps like the beeping tone caused by lack of

communications. Default Open (soft).

wJ5 – Shunt J5 if the DM02 is to be connected to Comfort’s DP04.

This will enable the LED indicator on the DP04 to be turned on

when the MIC is active.

wSW1 – Set of 3 shunts to set the ID (see “Door Station ID

Switch”).

LED Indicators

wD8 – Turns on when the microphone circuit is enabled; i.e. the

outdoor intercom is in talk mode.

Trimmers

wVR1 – MIC: Used to tune the microphone gain level from the

outdoor door station to Comfort.

wVR2 - VOICE: Used to tune the speaker gain level from Comfort to

the outdoor door station.

Switch

wSW2 – Doorbell: Simulates a press of the doorbell for testing.

Door Station ID Switch

Comfort is able to support up to 3 door stations. SW1 is a set of 3

headers which is used to determine the ID, in accordance to the following

table:

ID SW1-A SW1-B SW1-C

1Short Short Short

2Open Short Short

3Short Open Short

In the Comfigurator software, the number of door station must be set to

equal the maximum (ID) number of door station in the system. Do not

set door stations with the same IDs as this clash of IDs will result in

communication failure.

After changing the ID of the door station, remember to reset the DM02

by unplugging and plugging the 12V/COM terminal block.

After setting the IDs of the door stations in the system, the total number

of door stations must be set in the system.

To do this, set the number of door stations in Comfigurator to the correct

number. This can be found under “Configuration”->”Modules and

Settings”->”Number of Door Stations”.

Comfort DM02 Door Station Interface

Alternatively, the number of door stations may be set using the

keypad. To do so, login to Engineer Menu 7, 4, 1 and set location

1674 to the number of door stations.

The system must be reset in both cases for the changes to take effect

If any door station loses communications with Comfort, it will be

reported as “Communications Failure, ID#” where ID# is the ID for the

door station (49 for ID 1, 50 for ID 2, and 51 for ID 3).

Connection to DP04

The DP04 is a new version of the DP03 door station which must be

connected to a DM02 inside the house. DP04 contains the speaker and

microphone amplifiers and doorbell button. DP04 provide better security

compared to DP03 because the communications signals do not go outside

the house, but to the DM02 only. Using a DP04 also helps protects

Comfort from any damage due to nearby lighting surges, as this would

tend to affect the DP04 only, while the DM02 in the house may not be

affected.
