Dycon CAB0021 | Battery Link Cable for 24VDC PSU | 12VDC to 24VDC Conversion, T1 Connectors

FAQs

What cable do I need to connect a 7Ah battery to my Dycon power supply?

For 1.2Ah, 2.1Ah, 2.8Ah, 4Ah and 7Ah VRLA batteries, you need a cable with T1 (4.85mm) spade connectors on the battery end and a 2-pin Molex connector for the PSU. Dycon offers three lengths: CAB001 (300mm), CAB002 (485mm), and CAB039 (750mm). All Dycon battery backed-up PSUs come with a PCB-mounted 2-pin Molex (JST) socket as standard, and these cables connect directly to that socket.

How can I increase the battery capacity of my security system from 7Ah to 14Ah?

Use the Dycon CAB043 battery linking cable to connect two 7Ah batteries in parallel. This cable has two female T1 connectors that connect to the batteries, plus a female connector and male spade that works with the standard battery cable supplied with Dycon PSUs. When connected in parallel, the amperage capacity doubles from 7Ah to 14Ah, significantly extending the backup time of your security system.

What’s the difference between T1 and T2 spade connectors?

T1 spade connectors measure 4.85mm in width and are commonly used on smaller batteries (1.2Ah through 7Ah). T2 spade connectors measure 6.35mm in width and are typically used on larger battery applications and for earthing connections. Dycon offers terminal converters (FIX061 and FIX075) that allow you to adapt between these two sizes if you need to use an existing cable with a different battery terminal type.

Which cable should I use for connecting 17Ah or 24Ah batteries?

For larger 17Ah and 24Ah VRLA batteries, use Dycon’s M5 ring terminal cables which are specifically designed for these battery sizes. Available options include CAB035 (550mm), CAB037 (750mm), and CAB047 (300mm). These cables feature M5 ring terminals on the battery end and the standard 2-pin Molex connector for connection to Dycon PSUs. If you need to link two larger batteries in parallel, use the CAB042 M5 to M5 linking cable.

What are the splitter cables used for in a security system installation?

Dycon splitter cables (CAB017 and CAB018) are professionally-made 16AWG red and black cables with tinned ends, designed to provide reliable power connections from your PSU to peripheral devices such as output splitters, fire relay modules, or other system components. The tinned ends ensure secure connections to screw terminals, while the professional construction eliminates the need for on-site cable preparation. CAB017 is 180mm long and CAB018 is 450mm long to suit different cabinet layouts.

How do I safely earth a metal security equipment enclosure?

Dycon provides two earthing cable solutions. The CAB032 is a two-way earth cable with T2 (6.35mm) spade connectors and a tinned end, with the main section being 350mm and the tinned end section 150mm. For more comprehensive earthing where you need to earth the metal door, lid and base separately, use the CAB031 three-way earth cable which has three T2 spade connectors. These cables guard against electrical interference problems caused by poor earthing of control equipment.

Can I create a 24VDC system by linking two 12VDC batteries in series?

Yes, for 24VDC PSU configurations, you can use the Dycon CAB0021 red battery cable which links two 12VDC batteries in series to create 24V. This 250mm cable connects positive to negative terminals between the batteries. You’ll also need a standard battery cable to connect the remaining terminals to the PSU’s battery connector. This is particularly useful for applications requiring 24VDC output where higher voltage is needed for specific equipment.

What is the purpose of the fused power lead (CAB038)?

The CAB038 is a 1200mm 16AWG red/black cable with tinned ends on both sides and an inline bayonet fuse holder fitted with a replaceable 1A glass fuse. This provides overcurrent protection for power connections within your security system installation. The replaceable fuse means that in the event of a fault or overcurrent situation, you can simply replace the fuse rather than the entire cable, making maintenance easier and more cost-effective.
