KWCFC Posted June 29, 2019 Share Posted June 29, 2019 (edited) Hi guys I've got grade 3 site where the door contact on the automatic door keeps going into tamper - contact has been changed. The doors are metal, does the contact or magnet require spacing to stop magnetic interference? The contact and the magnet are also fitted quite close together, I heard someone suggest a while back that on grade 3 contacts there should be a bit of space between the magnet and contact.

sixwheeledbeast Posted June 29, 2019 Share Posted June 29, 2019 I rate the Elmdene ones for G3, you can wire them in a way so the magnetic interference shows as a separate masked signal. Had a few sites mainly engineering units where tampers would happen, most often in the day, tried most of the available G3 RSC's and found this was the best solution. Obviously G3 contacts have stricter mounting criteria (orientation, distance, alignment) over G2 but they are all designed to be mounted to a metal shutter directly as per the instructions.

james.wilson Posted June 29, 2019 Share Posted June 29, 2019 Use a grade 3 contact that is immune to external magnets etc rather than detects.

KWCFC Posted June 29, 2019 Author Share Posted June 29, 2019 It's CQR contact but I jumped the gun a bit guys. I got a callout to a tamper fault and assumed it was this door contact again... Turned out it was SAB tamper.. Doh!

Ain't that the truth, doesn't pay to have pre conceived ideas of a problem. It often catches you out. Customers Love us, Intruders Hate us.
