<div>Hi Guys,</div>
<div> </div>
<div>Any good recommendations on door release units?</div>
<div>I've heard of troubles with some models in the past.</div>
<div> </div>
<div>Facilities company is recommending these Viking products.</div>
<div>Any preference for FXO vs FXS?</div>
<div> </div>
<div>Cheers,</div>
