  2. 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

  9. Schlage RLBD AD-Series Relay Board

    Schlage RLBD Dry Contact Board For Either PIM400-TD2 Or PIB300-2D

    The Schlage AD-Series Relay Board (RLBD) supports the open architecture of AD-Series by building a bridge between Schlage technology and third party access control systems that use mechanical, relay-based communication. The RLBD relay board is used to extend the existing access point status signals on PIM400-TD2 (for AD-400 applications) or PIB300-2D (for AD-300 applications) devices for each access point controlled by the Interface Module. The optional RLBD relay board removes the need for custom wired relays which can be cumbersome to source, complicated to install, and difficult to troubleshoot. The use of this board over custom wired solutions increases system reliability and reduces installation labor. The RLBD is not required for integration with Schlage bright blue or other access control systems that use signal based communication such as RS485 & Wiegand. Learn More
