C S YO8 Super Yodalarm & Yodalight Series
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 a 10mm diameter mounting hole & sit on 250mm centers. The minimum recommended length of fixing screw is 30mm (not supplied).
- Avoid mounting the alarm where it could be subject to excessive vibration levels.
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 selectable alarm sounds (see table on the back of the installation sheet for details) and are selectable via switch SW1.
- A second stage tone is made available via a third wire connected to terminal TB1/3 as shown in Fig. 1.
- Alternatively, for DC units only, the 1st and 2nd stage sound signals can be generated by supply reversal see Figure 1, Option 2.
- Manually selectable second-stage tones are available for YO8 units by using switch SW2.
Line integrity on DC systems
- For 3 wire 2-stage alarm system, monitor via reverse polarity.
- 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
- As with the DC units, the AC units have a selectable tone via the SW1 DIP switch, see Figure 2.
- A second stage can be activated by applying an additional “N” connection to the TB3 terminal on the PCB, as shown in Figure 2.
Additional Voltage Options
- The Clifford and Snell YO8 Super series is also available in a 48vDC (F).
- The wiring for this voltage is the same as for the 24vDC units shown in Figure 1.
- Always confirm correct voltage is applied to relevant terminals.
YO8 Super Yodalarm/Yodalight Series
Consists of either the YA80 Super (Audible Unit only) or the YL80 Super
(Combined Audible & Visual unit) Connections for the YL80 Super units are made
via a 6-way Terminal Block mounted in the base of the unit as shown in Figure
3 (DC) & Figure 4 (AC) diagrams below. Using the connections shown, it is
possible to independently control both Sounder and Beacon sections.
