2.4 Extending Module Connection

2N IP Solo allows to connect the following extending modules:

• Security relay

Security Relay

The 2N IP Security Relay (Part No. 9159010) is used for enhancing security between the intercom and the connected electric lock. The 2N IP Intercom Security Relay is designed for any 2N IP intercom model with firmware versions 1.15 and higher. It significantly enhances security of the connected electric lock as it prevents lock opening by forced intercom tampering.

Function:

The 2N IP Intercom Security Relay is a device installed between an intercom (outside the secured area) and the electric lock (inside the secured area). The 2N IP Intercom Security Relay includes a relay that can only be activated if the valid opening code is received from the intercom.

Specifications:

Passive switch: NO and NC contacts, up to 30 V / 1 A AC/DC

Switched output:

• Where the security relay is fed from the intercom, 9 to 13 V DC is available on the output depending on the power supply (PoE: 9 V; adapter: source voltage of minus 1 V) / 400 mA DC.
• Where the security relay is fed from an external power supply, 12 V / 700 mA DC is available on the output.

Dimensions: 66.5 x 32.5 x 20.5 mm

Weight: 24 g

Installation:

Install the 2N IP Intercom Security Relay onto a two-wire cable between the intercom and the electric lock inside the area to be secured (typically behind the door). The device is powered and controlled via this two-wire cable and so can be added to an existing installation. Thanks to its compact dimensions, the device can be installed into a standard mounting box.

The Security relay is designed with holes for surface anchoring. It is recommended that a screw of the diameter of 3 mm with a lens head of the diameter of 6 mm is used. Using a countersunk head may cause irreversible damage to the plastic cover!

Connection:

Connect the 2N IP Intercom Security Relay to the intercom as follows:

• To the intercom active output (OUT1)

Connect the electric lock to the 2N IP IntercomSecurity Relay output as follows:

• To the switched output.
• To the passive output in series with the external power supply.

The device also supports a Departure button connected between the ‘PB’ and ‘- Helios IP/IP Intercom’ terminals. Press the Departure button to activate the output for 5 seconds.

Status signalling:

Configuration:

• Connect the 2N IP Intercom Security Relay to the properly set intercom switch output; refer to the Configuration manual for 2N IP intercoms. Make sure that one LED at least on the 2N IP intercom Security Relay is on or blinking.
• Press and hold the 2N IP Intercom Security Relay Reset button for 5 seconds to put the device in the programming mode (both the red and green LEDs are blinking).
• Activate the intercom switch using the keypad, telephone, etc. The first code sent from the intercom will be stored in the memory and considered valid. After code initialisation, the 2N IP Intercom Security Relay will pass into the operational mode (the green LED is blinking).
