Typical Four Zone System There are no four zone kits, but two to four zones can be accommodated by using any of the four zone Control Units in combination with the appropriate number of Reset Units, Over-Door Units and Pull Cord Units. There are no adverse effects if any of the four zone control units input connections are left open.
2. Introduction The basic system consists of a Control Unit (which is powered by AC mains supply) connected by an extra low voltage 2wire link to a Pull Cord Unit which is in turn connected to an Over-Door Unit by another extra low voltage 2-wire link. The Over-Door Unit is then connected to a Reset Unit by a further extra low voltage 2-wire link. 4 When the pull cord, mounted adjacent to the W.C., is pulled, the red L.E.D.
MUST be switched off at all times while installation is in progress • The installation shall be carried out in accordance with all applicable installation rules. • None of the units in the system should be subject to dripping or splashing liquids. • When using the Control Unit with a 25mm deep box choose the fixing holes to ensure clearance between the screw heads and the rear of the control unit. Wiring and Fixing Holes Final page gives expanded view of this diagram.
3.1. Control Unit This should be sited (following the recommendations of BS8300) where it can best attract the attention of an appropriate person/member of staff. An example of this is near a reception desk in view of a receptionist. Having located the site, install a flush or surface mount double gang wall box at least 25mm deep. Bring the mains supply cable (1mm2 twin and earth) into the box and connect to the terminals on the Control Unit marked ‘L’ and ‘N’ (see diagram).
Extra Low Voltage Wiring Important: Ensure that low voltage wiring are kept well away from mains wiring. The low voltage wiring must be tied to each other using the tie wrap provided to overcome clearances and creepage distances if any wire becomes detached. Bring the extra low voltage two core cable into the wall box and connect to the terminals marked output (see diagram). The system is not polarity conscious. Fix the Control Unit to the wall box using the screws provided.
3.2. Pull Cord Unit BS8300 (code of practice for the design of buildings and their approaches to meet the needs of disabled people) recommends that this should be sited on the ceiling such that for a toilet it can be operated from the W.C. and an adjacent floor area. The lower handle should be set 100mm above the floor (knot and trim off any excess cord) and the upper handle should be set between 800 and 1000mm above the floor (knot the cord at required height).
3.3. Over-Door Unit This should be sited to attract appropriate personnel to the area where assistance is required. An example of this is above the toilet cubicle door. Having located the site, install a flush or surface mount single gang wall box at least 25mm deep. Bring the extra low voltage two core cable from the Pull Cord Unit into the wall box and connect to the terminals marked input (see diagram).
4. Battery A battery is provided with the following control units and kits - EACP1PR, EASSCP1PR, EACP4PR or EASSCP4PR and cannot be fitted to other types. To fit the battery remove it from the holder and turn it round and offer it up to the connector and after correct polarity is ensured press the battery into the connector. The battery takes 48 hours to get to full charge from when first connected to the control unit and mains voltage applied to the L and N terminals.
5. Commissioning Switch on the mains supply to the Control Unit and check the left hand ‘Supply On’ indicator (green) is illuminated. The ‘Fault’ (yellow) and ‘Alarm’ (blue) indicators should be off. If the Fault indicator is illuminated this almost certainly indicates that there is an open or short circuit in the extra low voltage wiring. Assuming the Fault indicator is off pull the pull cord and the system should behave as described in the second paragraph of section 2.
