Clifford Snell YA80 Industrial Audible Signal Installation Guide

INSTALLATION & TECHNICAL INFORMATION
PLEASE READ PRIOR TO INSTALLATION YO8 Yodalarm & Yodalight Series
(Incorporating YA80 and YL80)
AUDIBLE AND/OR VISUAL SIGNALLING DEVICES
S00625 Issue 4

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 endof-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.
