Bosch Popit Wiring Diagram – The Ultimate Guide

Bosch is known for producing quality products and the Bosch Popit is no exception. The Popit is a compact, high-performance universal module that is specifically designed to work with fire alarm control panels. In this article, we will delve into the Bosch Popit wiring diagram, its features, how it works, and much more.

What is a Bosch Popit?

Before we dive into wiring diagrams, it’s important to understand what a Bosch Popit is. A Popit is a small device that is used to monitor and detect the status of input devices in a fire alarm system. These devices include smoke detectors, manual call points, and other similar devices.

The Popit acts as an interface between the input devices and the fire alarm control panel (FACP). It receives signals from the input devices and transmits them to the FACP. It can also receive signals from the FACP and translate them into actions for the output devices.

Bosch Popit Wiring Diagram – Basic Connections

The Bosch Popit is typically mounted inside the fire alarm control panel. Here is a basic wiring diagram that shows how to connect the Popit to the FACP:

Popit Terminal Wire Color Function
5 Black Common
6 Brown Input 1
7 Red Input 2
8 Orange Output 1
9 Yellow Output 2

Terminal 5 is the common terminal, while terminals 6 and 7 are the input terminals. Terminals 8 and 9 are the output terminals. The wire colors shown in the diagram are just for example purposes; you should refer to the installation guide for the correct wire color codes for your specific installation.

Additional Features of the Bosch Popit

The Bosch Popit has several additional features that make it a versatile and reliable device for fire alarm systems. Some of these features include:

High Input Sensitivity

The Popit has a high input sensitivity that allows it to detect very low-level signals from input devices. This means that it can detect even the slightest changes in the status of devices, ensuring that the system is always up to date.

Two Inputs and Two Outputs

The Popit has two input terminals and two output terminals. This allows it to monitor two separate groups of devices and activate two separate groups of output devices. This feature is especially useful in larger installations where multiple input and output devices are used.

Programmable Functions

The Popit is programmable, which means that you can customize its functions to suit your specific needs. For example, you can program it to activate specific output devices when certain input devices are triggered.

Bosch Popit Wiring Diagram – FAQs

Q: What wire size should I use to connect the Bosch Popit to the FACP?

A: The wire size you should use depends on the distance between the Popit and the FACP. For short distances, you can use a smaller wire size, such as 22 AWG. For longer distances, you should use a larger wire size, such as 18 AWG. Refer to the installation guide for the recommended wire size for your specific installation.

Q: How do I test the Bosch Popit?

A: To test the Popit, you will need to activate the input devices that are connected to it. You can do this manually by pressing the test button on a manual call point or by using a smoke detector tester. Once you have activated the input devices, you should check that the Popit has transmitted the signals to the FACP and that the output devices have been activated as expected.

Q: Can I use the Bosch Popit with non-Bosch fire alarm control panels?

A: Yes, the Bosch Popit is designed to work with most standard fire alarm control panels. However, you should refer to the installation guide to ensure that your specific panel is compatible with the Popit before installation.

Q: Can I connect multiple Bosch Popits to a single FACP?

A: Yes, you can connect multiple Popits to a single FACP. However, each Popit should be connected to a separate input zone on the FACP.

Q: How do I troubleshoot the Bosch Popit if it’s not working correctly?

A: If the Popit is not working correctly, you should first check the wiring connections to ensure that they are correct and secure. You should also check the input and output devices to ensure that they are functioning correctly. If these checks do not resolve the issue, you should refer to the troubleshooting section of the installation guide or contact Bosch technical support.


The Bosch Popit is a versatile and reliable device that is a popular choice for fire alarm systems. It is easy to install and program, and has several additional features that make it a top choice for professionals.
