Description

The Ademco SA5140-1 is a wiring harness kit designed to connect two alarm control panel backup batteries in parallel so that your alarm system will work for longer if and when you lose power to the system.

Wired alarm systems, like Honeywell's VISTA control panels, get power from an AC transformer that plugs into a standard wall outlet. The AC transformer (1361 or 1321 are popular transformers used with VISTA panels) plugged into the wall outlet steps down the high voltage power from the wall outlet and transforms it to low voltage 16.5 VAC output which powers the alarm control panel. Internally, the alarm panel then acts as a power supply itself to provide power to keypads, alarm receivers, alarm communicators, 4-wire alarm sensors, etc. Any professional alarm system will also have leads for a battery charging circuit so that you can hook up a backup battery so that your system will continue to work during a power outage (or if someone cuts the wire to your AC transformer).

We offer the Ultratech 1240 (4Ah) and the 1270 (7Ah) backup batteries but there are numerous types of similar sealed-lead acid batteries that you can use to provide backup power to your alarm system. Depending on how much power you are drawing from your panel's auxiliary power (for the keypads, receivers, communicators, sensors, etc) and the size of your battery, you can determine how long your system should stay operational during a loss of AC power. The higher the amperage hours (Ah), the longer the backup run-time.

If you are not happy with the amount of time your alarm system is staying powered on when switched over to backup battery power, you can use the SA5140-1 to wire up two separate backup batteries, in parallel so that it doubled the amperage hours and provides longer run-time during a power outage. Your alarm system's installation guide should have information about how long your panel will stay on during a loss of AC power. With a Honeywell VISTA-20P alarm system, a 4Ah battery will keep the panel running for 24 hours if you are drawing only 45mA from the panel's auxiliary power output. Both the Ultratech 1240 (4Ah) and the 1270 (7Ah) will fit side by side in the bottom of the metal alarm cabinet. However, the 1270s will be very tight so if you have other things on the bottom shelf of your alarm control panel, you probably won't be able to fit two 1270 batteries.

Excellent Battery Harness Kit
Submitted on 07/25/2019 Alarm Grid

We strongly recommend the Ademco SA5140-1 for anyone who wants to use a second backup battery with their Honeywell VISTA Alarm System. This convenient and easy to us wiring harness will allow you to connect two (2) backup batteries with the panel by wiring them in parallel. This will effectively double the battery life for the system. This is perfect for users who may experience frequent electrical outages. It is also great for users who want to ensure that their VISTA Panel will remain powered on for an extended period of time when the electricity is out, without having to rely on a power generator. Another excellent feature of this harness is that its positive legs have an inline fuse to prevent damage in case of a power surge.

Our technicians have found that it is easy to use the UltraTech 1240 4Ah Batteries and the UltraTech 1270 7Ah Batteries with the Ademco SA5140-1 Battery Harness. However, you should have no problem using this device with any of the similar sealed lead acid batteries that are compatible with hardwired alarm systems. Just be aware that you may have trouble fitting multiple batteries into your panel's metal enclosure. This will depend on the size of the metal enclosure and the size of the batteries. If that is the case you can always get a second enclosure to secure the batteries. Just make sure that the batteries are wired correctly at the panel in parallel.

Overall, the Ademco SA5140-1 is a great product. While it's not going to be useful for every VISTA user, those who can benefit from a second battery can put this accessory to great use. We believe that this is a fine battery harness to use with your Honeywell VISTA Panel if you intend on using two (2) separate backup batteries. Just be aware that it will take slightly longer for your batteries to obtain a full charge, as more power will need to be stored.

Look for similar items

Thanks. Will start the modification. You might want to edit the product listing to indicate what Vista panels this harness was mainly designed for and that modifications need to be made for the other panels.
This battery harness is usually used with the Vista-128BPT and similar panels. They have male tabs on the PCB that this harness connects to. The Vista-20P's battery wires are soldered into the board. I've looked for some type of female-to-female adapter, but have been unable to find one. To use this harness with a Vista-20P, you will have to cut and splice the wires unless you can find an adapter elsewhere.
There is no mention in your listing or review that this harness has to be spliced somehow into the existing Vista 20P battery connector that comes from the control panel. The control panel connector and this harness both have female ends. Do you offer some kind of connector for these two female ends?
