How to Install and Manage Aeotec ZW120 & Jasco ZW3605 Z-Wave Contact Sensors

Alarm.com supports both the Aeotec ZW120 and Jasco ZW3605 Z-Wave contact sensors. These devices are designed for non-security Z-Wave controllers (such as the Alarm.com Hub) and allow for automated control of your smart home system.

Installation

Step 1: Install the Sensor

• Install the door/window sensor following the manufacturer’s instructions.
• Mount indoors and away from moisture sources.
• Place within 90 feet of another Z-Wave repeater or the Hub.
• Align sensor and magnet dots within 1 cm of each other for proper function.
• Use screws when possible; mounting tape may require reinforced adhesive.

Step 2: Enroll Sensor to the Network

1. Remove the plastic battery tab on the sensor to power it.
2. Put the Hub in enrollment mode by pressing the enrollment button once — the light flashes green slowly and the Hub beeps once.
3. Press the Z-Wave button on the sensor once. If successful, the Hub beeps and the sensor’s LED turns solid for several seconds.

Note: If the sensor malfunctions after installation, perform a Z-Wave Network Rediscovery and press the Z-Wave button again.
