Qolsys QS1136-840 IQ DW Mini Wireless Door/Window Sensor

Qolsys QS1136-840 IQ DW Mini Wireless Sensor

Overview

The Qolsys QS1136-840 is a compact wireless door and window sensor designed for integration with Qolsys IQ alarm control panels. Operating on the 345MHz frequency band, this sensor provides perimeter monitoring for security systems across residential and small commercial installations. The IQ DW Mini form factor delivers a low-profile option for applications where traditional larger sensors are not practical.

Key Features

• Wireless 345MHz communication for reliable sensor-to-panel connectivity
• Compact mini form factor for discreet mounting on doors and windows
• Compatible with Qolsys IQ series control panels
• Door and window contact monitoring
• Designed for both residential and light commercial security deployments
• Standard wireless sensor battery and operational lifespan typical of Qolsys wireless sensors

Integration & Compatibility

The QS1136-840 integrates natively with Qolsys IQ control panels via 345MHz wireless protocol. Installers configuring Qolsys IQ-based systems will add this sensor through the panel's enrollment process, assigning it to specific entry points and security zones. The sensor's wireless architecture eliminates the need for hardwired connections to the control panel, reducing installation labor and allowing flexible placement around door frames and window sills.

System designers should plan sensor placement to ensure adequate signal strength from all monitored entry points to the control panel. Multiple sensors can be deployed across a single property, with each sensor maintaining independent communication with the IQ panel. Zone assignment and response logic are configured within the panel's programming interface.

Typical Applications

Security integrators deploy the Qolsys QS1136-840 for:

• Perimeter protection on residential properties with Qolsys IQ panels
• Entry point monitoring in small commercial facilities
• Retrofit installations where wired sensor runs are impractical
• Multi-zone systems requiring distributed contact sensors

The mini form factor is particularly suitable for aesthetic-conscious installations and applications where minimizing visible security hardware is a priority. The QS1136-840 sensor model number is sometimes referenced in documentation and ordering as QS1136 840 (with space notation).

James Everett

From a systems integration standpoint, the Qolsys QS1136-840 fills a specific role in IQ-based deployments where compact wireless entry sensors are required. During panel commissioning, this sensor pairs reliably and responds consistently to contact state changes. The 345MHz frequency band provides adequate range for typical residential and small-to-medium commercial properties when the panel is positioned centrally.

Technical Highlights:

• Wireless Protocol: 345MHz direct communication with Qolsys IQ control panels, enabling wireless enrollment and zone assignment
• Form Factor: Compact mini design reduces mounting profile and visual footprint on door/window installations
• Integration: Native compatibility with IQ series panel firmware requires no additional gateways or translators

Deployment Considerations:

• Verify signal path from each sensor location to the control panel during site survey; obstructions and distance can affect reliability
• Plan battery replacement intervals as part of ongoing system maintenance; coordinate with customer on notification procedures
• Document sensor assignments and zone mappings in the commissioning report to support future troubleshooting

The QS1136-840 is a straightforward addition to any Qolsys IQ perimeter security design. Pricing and availability through standard distribution channels make it a cost-effective choice for multi-zone installations.
