  3. 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
