LEM-1DLS Single-Door Access Sentry System Starter Kit with One Master Intercom

Great device

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.

Très bien documenté pour l'installation

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.
