2ENTRY Helios secondary switch
Order no. 9135250E
Description
The purpose of this module is to extend the 2ENTRY Helios door communicator with another
switch, e.g., for switching the electric door to locked. Comparing it to the previous switch
versions this one contains several modifications. It gives you features like unlimited time
switching or permanent switch during the time of the call. Thanks to the switching device latching relay – it is now possible for switching the low voltage logical inputs of e.g. gate and
barrier control systems. Both normally open (NO) and normally closed (NC) contacts are
available.
Caution:
Before installing the module, make sure that the current and voltage limits of the module will not
be exceeded in your application (refer to the Technical Parameters chapter). In no case use
this module for mains voltage switching!
Installation
1. Remove the screw from the left bottom side of the main communicator board.
2. Insert the switch connector onto the contact moulding (next to the hole for screw).
3. Insert a spacer ring between the communicator main board and the switch board and
hold the boards tightly together to the plastic back using the screw provided with the
switch.

Configuration
By using the connectors (jumpers) it is possible to set what kind of event should switch react by
closing or opening the contact. The switch can react to three different events: switch on/off of
the SWITCH 1, switch on/off of the SWITCH 2 and pick up/hang the telephone line (means
beginning and end of the call).
OFF
SWITCH 1 SWITCH
OFF
SWITCH 2 SWITCH
1
2
SPEAK SPEAK
ON
The switch input is available both normally open (between clips NO and C) as well as normally
closed contact (between clips C and NC).
Example 1 – switch operation by using password for SWITCH 2:
Switching on and off is set to SWITCH 2. Switch will close after receiving
password for SWITCH 2 (parameter 821) and open after the switching time for
SWITCH 2 (parameter 823) will elapse. In case of setting parameter 824 to nonzero value, will be also synchronized with SWITCH 1 (explained in the
communicator manual).
Example 2 – switch operation for unlimited time:
Switch closure is set to SWITCH 1, switch opening to SWITCH 2. The switch will
close when it has received the password for SWITCH 1 and will remain closed
until the communicator has received the password for SWITCH 2 and until the
switching time of SWITCH 2 elapses (parameter 823, it is recommended to set
this parameter as low as possible, which is 1s).
Example 3 – switch closure for the duration of the call:
Closure and opening is set to SPEAK. The switch will close when the line is
picked up and open when hung up. For the duration of the call the switch will be
closed.
