A couple of new innovative products have recently caught my attention. Here they are:
Security Door Controls (SDC) Model LR100VDK:
Field Installed Electric Latch Retraction Retrofit Kit for Von Duprin Exit Devices
This product is available now.

The mere 450mA inrush powering Security Door Controls’ new electric latch retraction retrofit kit is attractive enough. Its compatibility with all Von Duprin touch bar style devices may make it just about irresistible. Optional request to exit switch kits are available. The unit is usable for access control and electric dogging applications.
The small inrush is huge. (I always wanted to say that.) High inrush electric latch retraction requires special, expensive power supplies. Not so with the LR100VDK. Your average regulated and filtered 1-amp 24vdc power supply will do nicely, thank you.
Another great aspect of this kit is that it is compatible with the Von Duprin 22 series exit device. So now, for relatively short money you can give a customer electric latch retraction in a decent quality exit device.
HES Model 8500 Electric Strike for Mortise Locks
This product is due to become available by the end of August, 2011, but we’ll see.
Hanchett Entry Systems’ new lipless electric strike solution for mortise locks.
Installing an electric strike to release a mortise lock will be much easier with the HES 8500 since no cutting of the face of the frame is necessary. Below is an illustration showing the difference between the HES 1006 standard electric strike for mortise lock and the new HES 8500.

This is not a new idea, but installers seem excited about the prospect of having an alternative to the Securitron UnLatch, which has been around for quite some time. The Unlatch model that the HES 8500 will compete with will be the Securitron MUNL.
Of course, the advantage the MUNL currently enjoys is that, unlike the 8500, one can actually buy an MUNL. Comparatively, the Securitron requires a door frame depth of about 1-7/8 inches whereas the the 8500 will require about 1-3/8 inches. The 8500 will draw 240mA at 12 volts DC and 120mA at 24 volts DC and draws no inrush current. The MUNL has an inrush of 2 amps at 24vdc or 4 amps at 12vdc and an operating current of 600mA at 12vdc or 300mA at 24vdc. One important result of the lower current consumption of the 8500 will be that instead of the 4 amp 12vdc or 8 amp 24vdc power supply necessary for each MUNL, one 8 amp 24vdc power supply will theoretically power as many as perhaps 60 of the new HES 8500. Of course then, factors like wire run will come into play, but still.
Another positive attribute will be that the 8500 will be field selectable for fail safe or fail secure whereas the MUNL requires an additional module to make it fail safe.
All in all, the 8500 seems that it will be a better choice all around. We’ll just have to wait and see how it performs in the field after it becomes available at the end of August 2011.
