The spring on the
tamper contact must cling to the mounting surface so that the contact
opens at any attempt to pull off the keypad from the wall. The keypad tamper contact has no
connection with the system tamper circuit. Its state is defined by the control panel, based on
the data received from the keypad. In case two keypads are connected in parallel, the control
panel will detect tampering when both contacts are open. When the control panel is in the
service mode, the tamper contact and the keypad address are not controlled. Should the
panel alarm at the moment of exiting the service mode, it would mean an incorrectly
programmed address, or opening of the tamper contact.
Connection of detectors
The CA-6 can operate with detectors of any type. Each zone of the control panel can work in
the configuration NC, NO, EOL, 2EOL/NO, 2EOL/NC. When the zone works in an EOL
configuration, a 2.2 k
Ω
resistor should be used to make the detector circuit. In case of 2EOL
configuration, the detector circuit is closed by two 1.1 k
Ω
resistors. This type of zones
enables the status of detector and its tamper contact to be monitored at the same time.
The detectors may be supplied from any of the electronically protected outputs (OUT1 to
OUT3). The output should be programmed as the "POWER SUPPLY OUTPUT" (function
number 27). The use of OUT3 is suggested.
Separation of the detector power supply ground and the line ground makes it possible to
eliminate the effect of wiring resistance. Assuming that the wire is rather short, and only one
detector is connected to it, the installation can be simplified by using one wire for the power
supply ground (GND) and the signaling ground. The NO and NC detectors in 2EOL
configuration are connected in the same way, it is only important to correctly indicate to the
control panel, what type of detector is connected to the zone input (2EOL/NO or 2EOL/NC).
The figures below only show how the alarm relay outputs should be connected. Proper
connection of the detectors will require that power supply (COM, 12 V) be provided and TMP
terminals (tamper contact) of EOL or NO/NC detectors be connected to the tamper circuit.
