C S YO8 Yodalarm & Yodalight Series Clifford & Snell
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.
