Multifunction door alarm alerts to any unauthorized exits or entries through emergency exit doors and rear doors. If a protected door is opened, the electronic alarm emits an ear piercing siren for 30 seconds, three minutes or continuously. The powerful 95 of 105 dB warning horn immediately draws attention, helping to prevent misuse or theft through protected doors. A key operated override will silence the alarm and allow for authorized exits. The unit also has annunciation mode which announces a doors opening with a set of 10 beeps and then resets or it can be programmed for a 15 second entry delay or immediate trip. The unit is completely self-contained and easy to install.
