Average rating:

(based upon one review)

The Honeywell 4229 is an 8 hardwired zone expansion module with two relay outputs for powering external devices. This makes the 4229 Zone Expander perfect for users who want to use external hardwired sirens with their VISTA System. Purchase the 4229 Zone Expansion Module from Alarm Grid.

The Honeywell 4229 8 Zone Wired Expansion Module with 2 Relays serves as a convenient multipurpose module for a Honeywell VISTA Panel. It provides terminals for 8 additional hardwired sensors and two relay outputs for providing power to external hardwired electrical devices, such as sirens.

With the Honeywell 4229, you essentially get the same device as a Honeywell 4219 Expansion Module, along with two relay outputs. A user will typically add this module if they run out of zone terminals on the main system board. However, they should keep in mind the maximum number of zones that the system is capable of supporting. For a VISTA 15P, this is 22 hardwired zones. For a VISTA 20P or 21iP, this is 48 hardwired zones.

Each hardwired zone used with the 4229 can be supported by end-of-line resistors (EOLR) or use Normally Closed (NC) wiring. The wiring option can be selected using a configurable Dip Switch on the module. The module comes included with the necessary 2K ohm resistors for EOLR zones. Unused zones do not require resistors. Please note that 2-wire smokes and carbon monoxide sensors should be mounted to the main panel board rather than the 4229 Module.

However, the reason why a user would choose a Honeywell 4229 instead of a standard 4219 Zone Expander is because of the two relay outputs. This way, a user will not need to add a separate relay to control power to external devices. These devices can include hardwired sirens and other equipment that requires a power trigger to activate. The two on-board relays use a wiring harness rather than terminals. For that reason, you must consider wire colors when installing any relay device.

The current draw for the 4229 is 30mA when the relays are inactive, and 100mA once the relays activate. Make sure to accommodate for this and provide enough power for the relays to activate. The contact rating at each relay is 2A at 28 Volts AC or DC. It is impossible to run more current or voltage than that through one of the relays without risking damage to the module.

Nice Expansion Module w/ Relays!

The Honeywell 4229 is an 8-zone wired expansion module with two (2) relay outputs. This is a great device to use if you need to add support for additional wired zones to your system, while also adding two extra programmable relay outputs. It is very common to run out of wired zone inputs on a Honeywell VISTA System, so being able to add more with a device like the Honeywell 4229 can be very important. Overall, this is a very useful device with many practical applications. We give the Honeywell 4229 a 5-Star rating.

We have many positive aspects to discuss regarding the Honeywell 4229. The largest benefit is that the module provides eight (8) additional wired zone input terminals for the VISTA System so that the user can add more wired sensors. The two (2) relay outputs are also nice if you need to support a relay-triggered device, such as a siren or a strobe light. Included with the Honeywell 4229 are 2k ohm resistors. The resistors are important for letting the system know if someone tries to cut a sensor from the line.

There are a few downsides to the Honeywell 4229, but they are mostly minor. It is important to understand that the Honeywell 4229 doesn't technically increase the number of zones on a panel. It only adds additional zone input terminals so that more hardwired zones can be used. But you must still keep the total zone limitation for the panel in mind. Life-safety sensors, such as 2-wire smoke detectors and carbon monoxide sensors, should not be used with the Honeywell 4229, thereby representing another limitation. While resistors are included, wiring is not, so you must provide your own. The module draws some power from the panel. Specifically, it uses 30mA while the relays are inactive, and 100mA with active relays. And that does not include any powered sensors you might have connected with the Honeywell 4229. But really, these downsides aren't anything too serious. They do not stop us from rating the Honeywell 4229 with 5 Stars.

Good: Provides 8 Wired Zone Inputs, 2 Relay Outputs, Includes Resistors

Bad: Doesn't Actually Add More Zones, Does Not Support Life-Safety Sensors, Wiring Not Included, Draws Power From Panel

Bottom Line: 5 Stars

On the SMP3: With ‘SW1’ closed (ON) and ‘SW2’ open (OFF), the SMP3 has an output voltage of 6VDC. With ‘SW1’ open (OFF) and ‘SW2’ open (OFF), the power supply has a 12VDC output voltage. Finally with ‘SW1’ open (OFF) and ‘SW2’ closed (ON), the SMP3 power supply has an output voltage of 24VDC. The 4229 needs a minimum of 12Vdc to operate and the COSMOD2W requires a minimum of 12.p Vdc.
Can you power the 4229 and the COSMOD2W with a SMP3 2.5 Amps Aux power supply without any concerns .My plans were also to power up to seven 2WTA-B that will be connected to the COSMOD2W using the same power supply. From what I understand the from System Sensors website the 2WTA-B are Backwards compatible with COSMOD2W. I want be using the CO Zone . see attached photo..Thanks
Awesome! I am glad it worked :)
Worked like a charm. Thanks for the picture - very helpful.
This is how it should be connected. The power wires are not shown going all the way to the screw terminals so that you can see the terminal markings, but obviously, these should be connected to those screws.
After getting my 4W smoke wired up and tested to ensure it was working properly, I chose to tackle the reset function on the 4229, which is notably sparse on documentation. I reasoned the normally closed (NC) relay lead (orange) would go to the resettable power (2) on the 4229 and the common (C) relay lead (violet) would go to the power on the smoke. I left the 4229 ground (3) going directly to the smoke. I then programmed (*79/80) the 01 output to address the 4229 [08] and have the 01 output function as 'Fire Zone reset' (54). Unfortunately, this results in a fault on Zone 17 where my smokes are wired. Any suggestions?
Thank you for posting that information. CO detectors sometimes cause a trouble condition prior to an alarm condition. The zones on the panel are able to handle this and signal the alarm. The 4219 and 4229 don't always handle this correctly, meaning that they lock into trouble and don’t switch to alarm. For that reason, they always recommend against using CO detectors on expansion zones.
Update: Per Honeywell Home Tech Support the COSMOD is okay on the 4219/4229. However, not all CO detectors are compatible because some “open” before they “close” when activated, and the timing of this limits them used to only direct panel zones.
Is there a technical reason that the 4229 doesn't work with carbon monoxide detectors, or why they just say it doesn't work with "some"? My setup seems to work with the COSMOD4W.
Both the 4204 and 4229 relays will handle 2A @ 28VAC or DC (Resistive or Inductive loads).
Did Honeywell change the design and increase the contact rating on newer expansion module relays? I ask only because I looked at the relays on a 4229 and 4204 and each relay is marked "10A/240VAC, 28VDC" and the coil is marked "12VDC". I'm not knowledgeable on this topic, but I presume the input to the coil is 12VDC from the panel. I'm still uncertain about the rating on the contact side.
The relay contacts will handle 2A @ 28VAC or DC (Resistive or Inductive loads).
I checked the Honeywell site and the documentation does not list the relays contact rating ? for either the 4229 or 4204 units What are the voltage and current ratings ?
