  5. Command Access PM300 Power Boost Module w/ HO Switch

    Command Access PM300 Power Boost Module w/ HO Switch

    The PM300 is power booster interface module that fits inside of an electric latch pullback exit device. When energized by a 24VDC power source, it provides a local high current surge to the EL exit device to pull back the latchbolt. The PM300 utilizes smart technology to allow for both dual coil and single coil solenoids utilizing pulse width modulation. When utilizing the Command Access PS1, PS5-4, or PS5-6 power supplies, a simple slide of a switch engages the High Output mode to provide the additional pulse energy to overcome vertical rod and misalignment challenges. Since the unit is located inside the exit device or the hinge jamb, the typical wire run and power supply limitations are improved significantly by the PM300. Learn More

    MS SEDCO RLM Relay Lockout Module w/ Safety Beams

    The RLM is a microprocessor based relay lockout module with safety beams designed to meet the ANSI A156.10 2005 requirements that one-way traffic power operated pedestrian swing doors (typically supermarket doors) have an additional safety device installed when the overhead safety sensor is prevented from providing a safety signal during the closing cycle. The RLM is equipped with Intelligent Door Position™ monitoring circuitry that will automatically identify a swing door’s open and closed positions and determine its closing time. The RLM then controls the approach sensor, overhead safety sensor and safety beams. The proprietary software monitors the door’s position and controls when to inhibit the signal from the overhead safety sensor during the closing cycle while simultaneously monitoring the safety beams and when to prevent reactivaiton of the approach sensor.
