Trimec 188251-510 | Solenoid Lock Flush (Key Override) 12-24 V DC, Fail Open

Formerly Trimec (Tricare) TB25KOPTL

The TB25 range of drop bolts represent true engineering innovation, design excellence and the superior quality customers have come to expect and demand from Trimec. Designed for use on swing-through, double action doors, these drop bolts are ideal for applications where an electric strike is impractical.

The bolt is able to operate in horizontal and vertical orientations. The position of the bolt is monitored and has an integrated reed switch for door position monitoring.

The electronic functions include: 8 x lock and unlock attempts, 8 second unlock delay, automatic relock after 8 seconds, power reduction circuitry to limit the holding current, and a one time thermal fuse cut-out in case of solenoid overheating.

Locking function can be converted from Power to Lock (PTL) to Power to Open (PTO). The faceplate and strike plate are finished in stainless steel.

They offer a strong, dependable and long-lasting solenoid bolt solution.
