YA80 Industrial Audible Signal
Product Information
The YO8 Yodalarm & Yodalight Series is a range of audible
and/or visual signaling devices manufactured by Clifford &
Snell. These devices are designed to provide effective alarm
notification in various applications.
The YO8 series incorporates the YA80 and YL80 models, which are
approved and conform to the EN54-3 standard. They are suitable for
use in commercial and industrial settings.

Product Usage Instructions
- Prior to installation, it is essential to read and understand
the installation and technical information provided in the user
manual. - Ensure that the ferrite beads are correctly installed. Use one
wire per hole. Failure to install the ferrite beads properly may
result in the unit not complying with the EN54-3 approval. (YL80
Ferrite Beads are factory installed). - If using the audible signaling device (YA80), connect the wires
according to the wiring diagram provided. - If using the visual signaling device (YL80), ensure that SW1
& SW2 are configured to the same tone for the sounder to
operate in conjunction with the visual indication. - Refer to the user manual for additional configuration options
and troubleshooting guidelines.

Installation · Installation must be carried out in accordance with the latest codes of practice by a
qualified electrician. · Check that the power supply is correct for the voltage rating of the alarm to be
installed. · Ensure that the power supply is disconnected prior to installation or maintenance to
avoid electrical shock. · The unit should be mounted to a wall or bulkhead formed of suitable material using
the two mounting lugs projecting from the side of the enclosure. · The lugs have an 10mm diameter mounting hole & sit on 250mm centres. The
minimum recommended length of fixing screw is 30mm (not supplied). · Avoid mounting the alarm where it could subjected to excessive vibration levels. · All YA80 units require 2 additional ferrite beads (included in box) to be fitted on all input
wires, 1 wire per hole. Failure to correctly install the ferrite beads will result in the unit not complying with the EN54-3 approval. (YL80 Ferrite Beads are factory installed).
Ingress Protection To maintain the IP rating of the product, the below points must be observed. · An IP66 cable gland is supplied with the product. This gland (or other suitably rated)
must be used. · When replacing the front cover, each of the four retaining screws must be torqued
to 0.6Nm ±0.1Nm
Sound selection · Ensure the supply is OFF before proceeding. · All DC and AC units have 2 selectable alarm stages (see table on back of installation
sheet for details) and are set via switches SW1 & SW2. · Figure 1 (DC) & Figure 3 (AC) show wiring to activate alarm stages 1 & 2. · Figure 2 shows a second option for DC wiring. This allows for activating a stage 1 or
a stage 2 alarm tone depending on the polarity of the connection. · All stage 1 alarm tones have a predetermined stage 2 alarm (see back of installation
sheet), this will only sound if SW1 & SW2 are configured to the same tone.
Line integrity for DC systems only · For 3 wire 2 stage alarm system, monitor via reverse polarity across TB1 & TB2. · For 2 wire 2 stage alarm system, monitor via threshold, (applied voltage<1v) an end-
of-line (E.O.L) resistor is required for line monitoring and should have a minimum resistance of 3k3 ohms and 0.5watts, wire-wound or metal film type.
AC Systems · A second stage alarm tone can be activated by applying an additional “L” connection
to the TB3 terminal on the PCB, as shown in Figure 3.
Additional Voltage Options · The Clifford and Snell YO8 series is also available in a 48vDC (F) option. · The wiring for this voltage is the same as the 24vDC units as shown in Figure 1. · Always confirm correct voltage is applied to relevant terminals.

YO8 Yodalarm/Yodalight Series Consists of either the YA80 (Audible Unit only) or the YL80 (Combined Audible & Visual unit)
Connections for the YL80 units are made via a 6 way Terminal Block mounted in the base of the unit as shown in Figure 4 diagram below. Using connections shown, it is possible
to independently control both Sounder and Beacon sections.
