Integration module with alarm control panels. The rH-AC15S4R4 module is dedicated for integration with alarm control panels of any manufacturer. It has 15 high-resistance analog inputs, four low-voltage relay outputs and four 5-10 V optocoupler inputs. Communication with the server is via radio. The reference voltage value for each input is measured individually and stored for all inputs simultaneously, therefore it is allowed to use motion sensors of any manufacturer. Memorization of the reference voltage value enables cooperation with any voltage range of motion sensors. Relays and contact inputs work in the same way as in the rH-R3S3 module (without support for standalone mode).
