## Overview

The Aiphone LEM-1DLS is a professional-grade single-door intercom starter kit featuring a master intercom, weather-resistant door unit, and AC transformer. It delivers crystal-clear 100mW audio communication up to 650 feet via wired connection, with remote door-release capability for electric strikes (sold separately). Designed for robust, reliable access control in commercial or residential settings, it offers adjustable chime and volume controls and supports system expansion with additional master units.

## Description

The Aiphone LEM-1DLS single-door Access Sentry System starter kit includes one door intercom, one master intercom, and an AC transformer to enable audio communication with visitors at a door prior to granting access using the door-release button. The door-release button works with an electric strike (sold separately) to remotely unlock the entrance for the visitor. The master intercom emits an audible signal to indicate an incoming call from the door. Pressing the push-to-talk button allows the master intercom operator to talk to the visitor, and releasing the button automatically transmits sound from the door intercom. The chime and audio volume is adjustable on the master intercom. The housing is black plastic for the door intercom and white plastic for the master intercom. The master mounts to a desktop or wall using the included mounting hardware. Additional LEM-1DL master intercoms (sold separately) can be connected to the system using an Aiphone DAK-2S adapter (sold separately) to extend coverage into other rooms; each additional master requires its own AC transformer or DC power supply (sold separately).SpecificationsOverall dimensions (master intercom)7 x 5-1/2 x 2-1/4 inches/180 x 143 x 55 mm (H x W x D)*Overall dimensions (door intercom)4-3/4 x 3-7/18 x 1-1/8 inches/120 x 88 x 29 mm (H x W x D)*Communication output100 mWMaximum distance from door/sub to master650 ft. using a 22 AWG wire, 1,600 ft. using an 18 AWG wireCompatible wiresAiphone 822202 or 821802 (sold separately)Door strike connectionNormally open maximum 30VAC or 30VDC at 1 amp door release such as Aiphone EL-9S (sold separately)Power requirements12 to 16VAC or 12 to 24VDC.

Review: This product works very well. - Product worked great, over a distance of 300 feet using unshielded 18 ga cable. Plenty of volume, easy install, good documentation, and great product support staff in the USA who answered a question about operation—the master station is push to talk once a conversation is started with the remote. Other imported video door phones failed miserably to perform in the audio function (one or the other stations could not be heard.). Highly recommend this product for long distance communication to remote gates. Hard wired, not wireless.
Review: Do it right the first time - Several years ago I installed a battery-powered intercom not unlike the old RadioShack two-station intercom (due to familiarity in my parent's home). The unit eventually failed, but the Belden 8451 shielded two-conductor wire was still present and I installed this Aiphone unit. To say I should have done this the first time is an understatement. This is a superior unit in every way. Robust construction, excellent sound quality and sensitivity - testing revealed the remote station could clearly hear me from 30 feet away. Harsh call tone cuts thru audio clutter and has an internal volume switch. You will not be disappointed with the Aiphone product. You will need to supply your own 2-conductor power wiring for the AC transformer in the kit, as well as shielded 2-conductor station wire for communications. The master unit also has a remote-door-open switch that can be used with Aiphone strike plates or others with an isolation relay and power supply, but my application left this unused and untested. Installation instructions not for electrical newbies, but can be accomplished by most handypersons with some experience. Do it right the first time - if you need a great wired (up to 2300 feet with 16 gauge shielded) intercom, look no further.

### ⭐⭐⭐⭐ Purchased second unit. First one works fine.

Unit was easy to install and works fine. Needed a second unit for another location. Shielded wire is recommended to cut down on interference from and 110v lines nearby.
