AMS Solution Series & Eliminator Hoods O&M

This is a "temporary" mute activated by electric input. Your monitor has three dry contact relay inputs on the back. To enable Night Setback, you need to wire an external element (the hood power, the fan power, the room light, etc.) into one of the relay inputs. Then, when the external element changes states (turns on/turns off, etc.) it sends a signal to the relay to switch from open to closed. When the monitor enters Night Setback mode, the audible alarm is disabled. If there is an air fail, the red light will flash and the display will alternate between the velocity and "AIR FAIL." Then, when the external element changes states back to the original condition, the relay switches back and the alarm returns to normal operating mode (the horn is re-activated automatically). These steps are what you do on the monitor assuming you have connected to input 1. You or the electrician will determine which state you want the relay to be in during normal operation mode, and then when the external element changes state, the relay will flip and the alarm will be disabled. In the case when relay contacts are set to normally open when the unit is in standard operation mode: 1. Hold the enter button until you are given the choice between Run and Set Up. Choose Set Up. 2. Next, choose Configure (password is 0-0-0-0). 3. Next, choose Input 1. 4. Select "contacts close on activation" and press enter. The monitor will display "Input 1 activation set" for two seconds and bring you to the next screen, which allows you to choose a function. 5. From here, you choose Night Setback. The monitor will display "Input 1 function set" for two seconds and then return you to the Config menu. 6. Once back in the Config menu, scroll to Night Setback Mute. Hit enter and set to “Enabled.” 7. Select Done, this returns you to the main menu. 8. Select Run. 9. You should go back to the standard operation screen. Then, to make sure everything is set properly, you must activate the blower switch on and off while looking at the monitor to make sure the mode is changing as you intend. Once you've got this set up, no one has to physically do anything to the monitor for Night Setback mode to work. Simply flip the switch on whatever the external element is, and you're set. It is possible to use an output relay to send a signal when the monitor enters Night Setback mode. By using the output from one monitor and the input to a second, and so on, it would be possible to put all the alarms in an entire lab into setback by activating one switch.

4. Alarm Disable

Like Night Setback, this also is a "temporary" mute activated by electric input. The prime difference is this option generally is controlled at the hood level whereas Night Setback is typically administered at the room level or externally via a building management system and a programmed schedule.
