The LEM-1DLS Access Sentry System is a convenient 2-station entry control system and is suitable in various applications including offices of all sizes, courthouses, hotel / motel door entries, retail and convenience stores, and virtually any type of small secured facility. Identifying a visitor before allowing them access improves the security and adds convenience to any business. The set includes a desk or wall mount master station, a surface mount door station, and an AC transformer to power the system. A call from the door station sounds a momentary electronic tone at the master station. To answer, simply press the “talk” button to speak to the person outside the door, and release to listen. The person at the door station speaks hands free. A door release mechanism can be activated by pressing the door release button. The voice volume and the incoming call tone volumes are adjustable at the master station. The door release button is designed to activate an electric strike, or can be modified in the field to work with a magnetic lock. Different styles of door stations are also available: flush mount with stainless steel cover (LE-DA); surface mount metal (LE-DL). Vandal proof weather resistant (LS-NVP/B), flush mounted in a 3-gang masonry box, or surface mounted in the SBX-NVP.
