Technical Specifications

REX vs. Standard Latch Retraction

The MLRK1-HAG-REX includes request-to-exit monitoring for applications where a building's access-control or security panel needs to detect operation of the exit device. The separately designated MLRK1-HAG is the standard non-REX configuration unless its exact manufacturer order code states otherwise. REX is a monitoring contact, not a stand-alone access controller, door-position sensor or remote push button.

Compatible Exit-Device Selection

This listing is specified for Hager 4500 Series exit hardware. The underlying Command Access HAG-family design is also discussed in manufacturer literature for compatible IDC 8000, PDQ 6200, Stanley QED, LSDA 9000 and Lawrence 8000 series devices, but these may use different orderable kit SKUs. Do not assume this HAG-REX SKU substitutes for those models without written manufacturer confirmation.
