Door Open To Long (DOTL) sounders are used at a door to warn when the door has been left open longer than a pre-set time. They are also sometimes used in large retail stores with secure fire exits to alert staff if a customer opens the door. The problem is that in the event of

The Jack Fuse Power Port PP4F will no longer be stocked by our wholesalers. The PP4F was a four-way direct expansion module for the PP8FR. With the addition of the much more cost effective and smaller PP10HD to the Jack Fuse range we see little reason to continue the PP4F. Data and install notes will

Voltage drop issues in security systems can be avoided with some simple calculations leading to correct cable selection. Theory We power electric locks and other devices via sheathed copper cable. This cable has a known resistance per meter and the electric device will require a known current. The resistance causes the voltage to drop as
Security Cable Voltage Drop Part 2 Technical Calculations & Solution Read More »
Cable voltage drop refers to the lower potential available at the far end of a cable run compared to the potential available at the power supply end. Voltage drop in access control systems is often ignored until it presents a problem and can be difficult to diagnose. The effect of voltage drop is most often

If you are finding a mag (electromagnetic) lock to be “sticky” or slow to release it is likely that it has a diode connected across the power terminals. Remove it, problem solved. This is a common mistake. The reverse biased diode is supposed to prevent a current spike (often call back EMF) caused by the
