Extra Info
Reliable Wired Expansion
The DS-PM1-I8O2-H enhances the AX Hybrid Pro system by adding 8 fully wired zones, ideal for projects where stability and accuracy are required. This allows integration of traditional wired sensors alongside wireless devices for a hybrid solution.
Flexible Zone Configuration
With 3EOL resistor support (1kΩ alarm, 1kΩ tamper, 2.2kΩ fault), installers can fine-tune each zone to detect multiple conditions such as intrusion, tamper, and faults. This improves diagnostic capability and minimizes false alarms.
Long-Distance Communication
Featuring a dual Speed-X bus design, the module supports up to 900m distance per bus line, with cascading capability to add multiple expanders. This makes it suitable for both small buildings and larger sites with distributed zones.
Dedicated Power Output
The built-in 500 mA power output provides stable power to connected wired detectors, reducing the need for external supplies and simplifying installation.
Comprehensive Tamper Protection
Equipped with front and rear tamper switches, the expander protects against unauthorized opening or removal, ensuring system security at both physical and electronic levels.
Installer-Friendly Indicators
Onboard LED indicators (Power and Fault) give at-a-glance system status, helping installers quickly verify proper operation and detect issues during setup and maintenance.
Q&A
