About this product

The Hochiki YBO-R/6PA is a conventional detector mounting base for 2-wire systems, where detectors and sounders share the same zone cables. It suits installers working on that type of panel; control panel compatibility is required. It has an integral remote indicator output and a dedicated cable screen terminal.

Key features

  • Shows an alarm somewhere else – integral remote indicator output
  • Keeps the screen tidy – dedicated cable screen terminal
  • Quick to terminate – square cable clamps, taking 1 to 2.5 mm² cables
  • Easy head fitting – bayonet slot with low insertion force
  • Built for site life – rugged design in ABS

For installers

  • Power: 15 – 30 V dc from the zone.
  • Mounting: 100 mm diameter, 13 mm high; fixing centres 48 ~ 74 mm.
  • Cabling: square cable clamps for 1 to 2.5 mm² cables; terminals A Zone (+), B Zone (-), C Cable Screen.
  • Compatibility: for 2-wire systems with detectors and sounders on the same zone cables; control panel compatibility required.

Frequently asked questions

What is a 2-wire detector base for?

Systems where detectors and sounders sit on the same zone cables. The panel must be compatible with this base.

Which detectors fit the YBO-R/6PA?

Hochiki's conventional SLR-E3/SLR-E3N, DCD-AE3, DCD-CE3, DFJ-AE3 and DFJ-CE3 detectors.

What colour is it?

Ivory White ABS.

What cable sizes does it take?

From 1 to 2.5 mm² in the square cable clamps.

Can the detector head be locked on?

Yes. Remove the plastic lug on the underside of the detector, and the head then needs a removal tool to take it off.

Hochiki Conventional 2-Wire Detector Base, Ivory White YBO-R/6PA

Overview

A detector base is the part that stays on the ceiling: it takes the cables, and the detector head twists into it. This Hochiki base is the one to fit where a conventional system runs detectors and sounders on the same pair of zone cables.

Most conventional systems run separate detector and sounder circuits, so a 2-wire system needs a matching panel and this special base. The panel's compatibility has to be confirmed before fitting.

How it works

  • Zone and screen: the zone pair and the cable screen each land on their own marked terminal, so the screen is carried through cleanly.
  • Remote indicator: the conventional detectors that fit use three terminals, so they can drive a remote indicator through the base's integral output.
  • Bayonet fitting: the detector head locates in a bayonet slot that needs little force, and it can be locked on by removing a lug from the detector.

Where to use it

It belongs on 2-wire conventional fire systems, indoors, between -10°C and +50°C and up to 95% relative humidity without condensation. It is one of several fire detector bases in the range, each made for a different job.

What the figures mean in practice

  • 15 – 30 V dc: the zone voltage range the base works on; check the panel's zone output sits inside it.
  • 1 to 2.5 mm²: the conductor sizes the clamps take, which covers the usual fire alarm cable cores.
  • 48 ~ 74 mm: the spread of fixing centres, which lets the base suit a range of boxes and fixings.

Installing it

Wire the zone and screen to the marked terminals, then twist in a compatible head, such as the DFJ-AE3 fixed temperature detector or the DCD-AE3 rate of rise detector. The SLR-E3 and SLR-E3N smoke detectors fit it too.

The heat detectors and smoke detectors it carries are made for indoor use only. Test every detector after installation.

Planning your system

Confirm the panel supports 2-wire working before buying, because this base is for that wiring method only. Fit one base per detector, and plan any remote indicators at the same time, since the output is built in.
