The LCN 9540IQ-519 is the OEM DPS (Door Position Switch) cable for the 9540IQ Senior Swing electromechanical door operator. The DPS cable connects the door position monitoring circuit on the 9540IQ control box to external access control, building management, or security systems that need real-time door status-open, closed, or in motion. Without this cable properly connected and seated, the control box cannot transmit position data to downstream monitoring equipment, and any access control integration tied to door status feedback will lose visibility into the door's operational state.

The 9540IQ is LCN's current-generation Senior Swing heavy-duty electromechanical automatic operator for single-door push-side applications, part of Allegion's updated IQ product family that replaces the legacy 9540 Series. The IQ platform introduced the AdaptivIQ controller-an onboard microprocessor that automatically adjusts opening speed, closing force, Smart Power Boost, and back-check in real time based on environmental factors including wind pressure, carpet drag, and HVAC stack pressure. This self-calibrating architecture means the 9540IQ's control box handles far more signal integration than older operator controllers, making accessories like the 519 DPS cable central to a fully functional installation rather than optional add-ons.

LCN 9540 Door Operator DPS Cable Function and Control Box Integration

The 9540IQ Senior Swing control box is a fully loaded controller with 23 programmable settings, accessible through an onboard LCD screen. It runs on 115VAC single-phase at 60Hz (240VAC 50/60Hz also available) and delivers 24VDC output at 2 amps to power actuators, card readers, and safety sensor circuits. The DPS signal circuit is one of several low-voltage peripheral connections the control box manages alongside actuator inputs, safety sensor lines, electric lock coordination, and the companion motor cable for double-door configurations.

The door position signal specifically tells connected systems whether the door leaf has cleared its threshold, reached full open, or returned to the closed and latched position. For access control applications where door prop alarms, hold-open monitoring, or entry/exit audit trails are required, this signal is non-negotiable. The 9540IQ-519 cable provides the physical connector and correct wiring specification to link the DPS circuit on the control box to a card reader controller, alarm panel, or building management system without field-fabricating a connection.

LCN Auto Door Operator Parts: 9540IQ Accessory Ecosystem

The 9540IQ ships as a self-contained unit with the motor gearbox, control box, baseplate manufactured to specified door width, cover end cap kit, and machine screws. Field accessories ordered separately include the regular arm (9540IQ-3077), long arm (9540IQ-3077L), telescoping arm (9540IQ-3077TLS), telescoping long arm (9540IQ-3077LNGTLS), and the rocker switch assembly (9540IQ-3179). The DPS cable is an accessory that connects to the fully loaded control box for building system integration and is ordered separately when the installation requires door position monitoring-which is the case in most institutional, healthcare, education, and secured commercial entries where the 9540IQ is specified.

The 9540IQ meets ANSI A156.19 for low-energy power-operated doors, is UL325 and UL228 listed, UL10C listed for fire-rated door applications, ADA compliant, and listed under the Buy American Act (BAA). It handles doors up to 600 lbs and door widths from 33 to 48 inches on single-door configurations. Finishes available are 628 (aluminum anodized) and 710 (dark bronze anodized).
