The Honeywell 4204 Intelligent Relay Board adds between one and four Form C relay outputs to compatible alarm control panels. The module connects directly with the keypad bus for easy wiring. It can be placed inside the metal cabinet or mounted in a separate enclosure for protection.

If the 4204 is mounted away from the panel, a built-in tamper switch will let the system know if it is ever opened up for any reason. Please note that all communication to the 4204 module is supervised. This means that it cannot be disconnected from the keypad bus without detection. When setting up the 4204, its DIP switches must be configured to determine which relay outputs will be active. The devices measures 4.25"L x 6.44"W x 1.25"D.

Great Relay Module Add-On
Submitted on 08/11/2020 Alarm Grid

The Honeywell 4204 is a relay board add-on for Honeywell VISTA Security Systems. This device will add up to four (4) programmable relay outputs for a compatible system. The relay outputs can then be used to activated relay-triggered devices, such as sirens and strobe lights. The device is compact enough to fit inside the main panel's metal enclosure, but it can also be installed outside the enclosure if desired. Overall, the Honeywell 4204 is a great device to use if you need to add additional relay outputs to your Honeywell VISTA System. We give the Honeywell 4204 a 5 Star rating.

There are many positive aspects regarding the Honeywell 4204. Adding four relay outputs to a system is a great benefit. This will provide you with many options for setting up relay-triggered devices. And even if you don't use all four relay outputs right away, you can always go back and add additional devices later on. The size of the unit is definitely a benefit, as you have the choice to mount the unit either inside or outside the panel's metal enclosure. Most users choose to install the device inside the metal cabinet, but you may want to mount it outside if the metal enclosure is already filled up. The device is UL listed for both burglary and fire in residential and commercial installations. A tamper switch can be enabled to let the system know if someone opens up the module. The relay outputs are Form C, meaning that either Normally Open (NO) or Normally Closed (NC) wiring can be used.

There are not many downsides regarding the Honeywell 4204. It will need to be installed and wired to the panel. Programming the Honeywell 4204 can be a bit tricky. Luckily, you only need to set it up once. The device will draw some power from the panel, so make sure to consider it when doing your power calculation. But really, these downsides are very minor, and they do not stop us from giving the Honeywell 4204 a perfect 5 Star score.

Good: Four Relay Outputs, Compact Size, UL Listed, Tamper Switch, Form C

Bad: Installation Required, Difficult to Program, Draws Power

Bottom Line: 5 Stars

We aren't sure why Honeywell didn't list that detail on any of their documents. They do list it on their internal site designed for alarm dealers and we added it to the 4229 page but failed to add it to the 4204 page. We're glad to hear you found the information you needed on our site and let us know if you need anything else.
Thank you, your reply addressed my primary question regarding the contact rating on the 4204. I asked because the contact rating is listed for on the product page for the 4229, but it wasn't listed on this page for the 4204. My last question that you didn't "follow" was based on my assumption (as it turns out an incorrect assumption) that the 4204 contacts were rated as marked on the relay and the 4229 contacts were rated lower at 2A (as indicated on that 4229 product page). Your response clarifies that the contacts on both, the 4204 and the 4229, are rated 2A each relay. Unfortunately, this information doesn't appear anywhere I could find by reading the data/cut sheet, the installation instructions, the schematic for either module, or by searching Honeywell's web pages or elsewhere online. AlarmGrid is the only vendor I found that provides this crucial information. Anyway, 2A for LV is quite adequate for accessories. An 8A power supply with DC output and a stand-by battery to power 4 active, 2A accessories/circuits, is quite substantial. Thanks again and hopefully this information helps others considering to add a 4204 (or a 4229).
Both the 4204 and 4229 relays will handle 2A @ 28VAC or DC (Resistive or Inductive loads). I'm not sure I'm following your last question though. Can you clarify?
What is the contact rating for each relay on the 4204? Is it different from the 4229? I noticed the two expansion modules utilize the same relays, but the contact terminal/connection types are different on each of these modules. Is the contact rating de-rated on the 4229 because of the pin connector/wiring harness type connection? Thanks.
