Alarm Controls GDH – Frequently Asked Questions
1) What does the Alarm Controls GDH glass door holder actually do on a frameless glass door?
The GDH is the mounting bracket that lets an Alarm Controls 600 or 1200 Series magnetic lock be used on a glass door. The maglock body mounts to the header, and the GDH is what carries the armature on a glass leaf that has no top rail to bolt into. It is an accessory, not a lock: you order it in addition to the maglock, not instead of one.
2) I have an Alarm Controls maglock on a glass door but it is not a 600 or 1200 Series. Will the GDH holder fit it?
No. The GDH glass door holder is built for the Alarm Controls 600 and 1200 Series maglocks only. Armature plates and bracket geometry differ between maglock families, so match the holder to the series stamped on the lock you are installing. If the lock is a 600 or a 1200, this is the glass door holder for it.
3) Will the Alarm Controls GDH glass door holder match my aluminum storefront doors?
Finish is clear anodized, US28, which is the standard satin aluminum look on commercial storefront and glass entry doors. It reads the same as clear anodized aluminum frames and most aluminum-finish maglock housings, so it blends on a typical glass front rather than standing out. Clear anodized is the only finish the GDH is made in.
4) Is the Alarm Controls GDH glass door holder rated for a commercial entrance, or is it a light-duty residential part?
Commercial. The GDH is part of the Alarm Controls access control accessory line and is specified for commercial glass entries running 600 or 1200 Series maglocks, the kind of opening a property manager or integrator is securing at a storefront or lobby door rather than a house.
