Summary
The Haydon HAY-FIRE-24R is a 24V DC fire relay for switching auxiliary equipment from your fire alarm system, with double pole contacts rated at 5A @ 250V AC. That gives you two switched poles from a single 24V DC signal, in one boxed unit.

It arrives with its own surface back box, so you are not sourcing a separate enclosure or pattress for the job. The 86mm x 86mm faceplate is marked “Auxiliary Relay Operated” and carries a red indicator, so you and the end user can see the relay’s state at a glance during commissioning and routine testing.
The coil draws a nominal 22mA at 24V DC, which keeps the load on the supply modest and makes it simple to account for in your standby battery calculations.
Features
- Double pole relay – two switched poles from one 24V DC signal
- 5A @ 250V AC contact rating – headroom for switching mains-rated auxiliary loads within the stated limit
- Surface back box supplied – no separate enclosure to source, so the unit is ready to mount
- Marked faceplate with indicator – “Auxiliary Relay Operated” legend and red indicator make the relay’s state easy to identify on site
- 22mA nominal current consumption – a modest, known load for your supply and battery calculations
- Standard 86mm x 86mm footprint – a familiar single gang size that sits neatly alongside other wall-mounted accessories
- 3 year warranty – manufacturer cover for peace of mind after handover

FAQ
It is a 24V DC device, with the datasheet giving a 10% tolerance on that operating voltage. It is not specified for 12V systems, so use it only where a 24V DC signal or supply is available. Allow for its 22mA nominal current when you work out panel loading and standby battery capacity. No. A surface back box is supplied with the relay, so it is ready to fix straight to the surface. Allow for an overall depth of 62mm with the back box fitted. The datasheet confirms a double pole relay rated at 5A @ 250V AC but does not state the contact arrangement. If your application depends on a specific arrangement, confirm it with Haydon or check the terminal markings on the unit before you design it in. The datasheet does not say whether the coil is polarised or suppressed, which is what you would need to know before connecting any relay across a monitored circuit. Confirm this with Haydon first, or drive the relay from a suitable 24V DC auxiliary output instead. The faceplate is marked “Auxiliary Relay Operated” and has a red indicator in the centre. This gives you a visual reference at the unit itself, which is useful when you are testing cause and effect during commissioning.What supply does the HAY-FIRE-24R need?
