The initial call came in late on a Friday. The facilities management company wanted us to adjust the exit device controlling the main entry to a building housing a retail bank branch as well as eight floors of tenant’s offices. I was familiar with the building, since we had installed a HID Solo on...

The 510 Series is modular; adding further flexibility, ease and convenience to power electronic locking systems. For example, plug-in dual control modules can be added for independent control of up to six zones. Each dual control module (DCM) can provide control for two independent zones (six zones at 24VDC/300mA, or 12VDC/500mA).
Up to three dual control modules can fit into a control module rack (CMR). A plug-in adjustable relock time delay module (TDM) is available with a 0 to 30 second delay. It plugs into each zone of the dual control module to provide up to six TDM’s in each power supply.
We supplied the 510 with the emergency interface relay (EIR) module which plugs into the main circuit board to provides interface with approved fire or other emergency systems. A signal from the emergency systems automatically and instantly unlocks all locks connected to the power supply.
Altronix RB1224 Relay
This is one of my favorite problem solvers from Altronix. I always have these on hand because they’re so versatile. Relays are important for transitioning to provide isolation between different elements of the system where different voltages or grounds may exist.
The on-board red LED is quite helpful when troubleshooting, the 5 Amp contacts are usually more than adequate for most electric locking devices, and the field-selectable coil voltage cuts down inventory. This relay coil draws 75 mA. Altronix offers other relays with lower current draw, but as I say, the RB1224 is fine for most of my access control interfacing applications.
I like to mount them with plastic track rather than two-sided tape. It looks a lot neater and more professional.
I know the end-user will call right away if something goes wrong with this door, because due to his stubbornness and unwillingness to listen to reason, the final charges for all the service calls in addition to the maglock installation cost him plenty.
Important: Before installing electronic locks, it is important to check with the “Local Authority Having Jurisdiction” (LAHJ). An electromagnetic lock is designed to provide security for a...
A small high-tech software firm had leased a new space and they needed to get things secured. They wanted their security put into place quickly so as to minimize losses, but also stipulated that the...
Electromagnetic locks are sometimes regarded as an “idiot-proof locking solution” for unskilled installers or for use on problem doors.
