RS-1-12V coordination board between the Octopus flooding detector and the security center or GSM module.
The RS-1-12V board analyzes the state of the detector and generates an alarm signal with relay contacts.
Thanks to the PC-1-12 pair board, the flood detector can be connected to almost any security device or other executive device, for example, an electric clamp, an electric pump, etc.
The maximum number of Octopus detectors that can be simultaneously connected to the PC-1-12 board is 5 pcs.
The PC-1 board consists of a 9-pin screw block, radio elements and an AB jumper that provides alarm memory.
Working principle:
The supply voltage of 12V DC is supplied to contacts 1(+), 2(-) of the 12V screw block. The voltage of positive polarity is applied to pin 5(K) of the screw block, to which the positive wire or pin of the device requiring matching is connected, and the negative wire or pin to pin 6(E).
In standby mode, the current does not flow from contact 5(K) to contact 6(E) of the screw block, there is no potential on contacts 3 and 4 (LED), the remote LED does not light up.
In the alarm mode, the Octopus detector connects contacts 5 and 6, which leads to the connection of contacts 7(COM) and 9(NO), and when the remote LED is turned on, it starts to light up.
If the AB jumper is not installed, contacts 7(COM) and 8(NC) are opened and contacts 7(COM) and 9(NO) are closed, and the remote LED is lit only for the duration of the alarm.
Contacts 8(NC) and 7(COM) are closed in "Standby mode" and open in "Alarm" mode
Contacts 9(NO) and 7(COM) are open in "Standby mode" and closed in "Alarm" mode
Contacts 9(NO), 8(NC) and 7(COM) are used for connecting to loops of receiving and control devices, or for connecting executive devices.
