    Installation manual for the SECO-LARM Enforcer SD-7X13-XSP / SD-7X73-XSP series Request-to-Exit Plates with Pneumatic Timer — a zero-power, mechanical timing solution for exit-delay applications.

    Introduction

    The Enforcer SD-7X13-XSP series Request-to-Exit Plates with Pneumatic Timer are ideal for applications where providing power to a timer is inconvenient, hazardous, or non-conforming with local codes and ordinances. The timer functions entirely without electricity, using reliable American-made pneumatic components. Adjusting the delay time is easy via a timing screw and can be performed on the spot without tools.

    Installation

    1. Find a suitable location for the pneumatic request-to-exit plate.
    2. The plate can be surface mounted or flush mounted.
    3. Wire the plate as described under Wiring, below.
    4. Adjust the timer as described under Adjusting the Timer, below.
    5. Test the function of the exit plate and timer, including the timer delay.
    6. Mount the plate in a back-box or other suitable housing.

    Wiring

    • For N.C. operation (fail safe): connect the red wires to the electronic lock or other device.
    • For N.O. operation (fail secure): connect the white wires to the electronic lock or other device.

    Adjusting the Timer

    1. Locate the timing screw on the timer assembly.
    2. Using fingers or a flat screwdriver, turn the timing screw gently: tighten clockwise to increase delay, loosen counterclockwise to decrease delay.
    3. Do not over-tighten or over-loosen the timing screw. If it becomes very loose, retighten it until it feels secure.
    4. Minimum delay is approximately 1 second, maximum is approximately 60 seconds. Use a stopwatch to fine-tune the setting for the application.

    Example Installation

    An SD-7173-SSP (or similar) RTE plate with pneumatic timer wires to an electronic lock (fail-safe/N.C. operation, red wires) or an EAP-5D1Q access control power supply feeding an Enforcer series electromagnetic lock. Use these plates anywhere zero-spark switching is required.
