Installation - Conrad Electronic Renkforce 752181 Operating Instructions Manual

7. Installation

The voltage required for operation is 12 - 16 V/DC at the terminal clamps 1 (+) and 2 (-). Ensure
correct polarity to avoid damage to the product!
We recommend also connecting a lead battery (12 V, 1.2 Ah), to maintain operation in case of
power outage.
Only activate operating voltage after performing all connections and setting the jumpers.
Now connect the different system components of the system.

Sensors with NC and NO contacts can be used for all alarm zones (1 - 6).
N.O. = Normally Open contacts, sensors with open contacts - closed during alarm
N.C. = Normally Closed contacts, sensors with closed contacts – open during alarm
If no sensors with NC-contacts are used, a 2.2kOhm EOL resistor must be installed to secure the
circuit (included in the delivery).
Connect the sensors with NC contacts in series and the sensors with NO contacts in parallel.
To ensure proper operation of the NC contact sensors, ensure that each sensor's impedance
does not exceed 1kOhm.
