Alarm Locks PG21 Pilfer Guard has been updated. Some changes on the electronics make this a real new and improved model. We tested this in a high frequency door and found that they alarm maintains a steady 105 db output when the door is opened. We had selected a 2 minute sounder and the alarm maintained a steady 105 db for the entire 2 minutes. When the system shut down, it did continue to give us a “chirp” alert until we reset the system with the override key. Battery life is determined by the amount of usage of the alarm sounder, but for the most part, it maintained power for over 100 alarms during our test. Easy to install unless you want a key cylinder on the outside of the door. We would recommend a professional. It comes with all the mounting hardware, screws and mounting templates. The key cylinder is a standard mortise cylinder that can be keyed into any businesses master key system, or just keyed alike for more than one unit. if you require a key override on the outside, this is a standard rim cylinder and can be matched with the same key as the inside mortise cylinder.
