You need to buy an Annunciator but don’t know where to start? we have complied a list of everything you need to consider when looking for the right Annunciator and tips on how you might be able to save time, money and space for your project.
1. The first part of looking for the right solution for your project is to decide if you need a full functioning Annunciator which includes a logic card that gives you advanced features or you can simply use a Light Box that just indicates the ON/OFF status of input signals.
2. You need to find out how many alarm points you need to monitor. This will help when deciding the size of your Annunciator and allow you to understand the specifications of your project.
3. You need to identify the available space for your Annunciator. For example, if you are replacing an older system, most likely, you are restricted to the existing cut-out dimensions. For replacing an existing Annunciator, try to select a configuration close (but smaller than) the existing cut-out dimensions, then you can make an adapter to cover the gap between the old cut-out and the new unit.
4. Some modular Annunciators have different window sizes (usually, large, medium and small). Considering the size of windows and overall dimensions of the unit, you can proceed to find the one that fits the available space.
5. Understand how you want your Annunciator inputs to be triggered. It could be a dry contact (voltage free) or a wet contact (voltage) signal. If it is voltage, you need to know how many volts will be used to activate each window.
6. Decide the key features you need for your Annunciator:
– Mounting type (panel-mount, wall-mount, rack-mount, …)
– Any individual Auxiliary Relays (Repeat Relays) needed?
– Any common output (Horn, Common Alarm, Firs-out, …) Relays needed?
– Any built-in pushbuttons (Acknowledge, Reset, Test, …) needed?
– Any communication with other devices (RS485, Ethernet, …) needed?
– Any other specifications (such as data logging, printing, …) needed?
7. Have a general idea about the windows appearance. For example, the color of each window (i.e. Yellow for Alarm, Red for Shutdown, …), or maybe you prefer bi-color windows (i.e. Green for Normal, Red for Alarm, …). Your Annunciator can also have an audible device such as a horn for a sound effect to further enhance the experience.
8. Have a general idea of your overall budget for the Annunciator section of your project.
9. Understand your projects schedule and know exactly when you need your Annunciators to be ready
