- Description
- This project specifies the following work: In the course of this energy saving project occupancy sensors are installed on the ceilings in the buildings # 602, 606, 610, 614, 618, 680, 681, 682 and 683 so that the lighting in the long hallways and the staircases is switched automatically and as needed within defined zones. Three (3) different types of ceiling-mounted occupancy sensors will be installed. A separate sensor is planned for each landing in the staircases, switching all mounted light fixtures of the respective landing. Currently the light fixtures in the staircases are switched by a common circuit for the retractive switches. It is intended to jumper the appropriate impulse relay in the distribution board to realize the light fixture switching via the occupancy detectors, that means 230 V are permanently applied to the existing light fixture, and the light fixture supplies the respective occupancy detector. The respective occupancy detector is to be mounted with a base close to the existing light fixture. Since there are mostly surface-mounted light fixtures in the staircases, the bases are used to slightly increase the occupancy detector height and so improve the detection range of the sensor. Additionally the occupancy detector and the light fixture are to be connected. To do so a cable gland must be installed in each light fixture and the light fixture wiring must be modified correlatively. The occupancy sensor will be supplied with 230 V from the light fixture and in turn switches all light fixtures on the landing in case of occupancy detection. This method of realization enables the desired switching without new cables being routed in the staircase. The existing retractive switches must be removed, the cables isolated and the switch boxes covered with blind caps. Occupancy detectors with a larger detection range will be used in the long hallways, partly as master detectors, partly as master- slave detectors. The occupancy detectors are to be mounted directly on the ceilings, in case of surface-mounted light fixtures with a base - same as for the staircases. The occupancy sensors are to be wired above the ceiling, whereby the same method as used in the staircases is intended: jumpering of the impulse relay and so supply of the occupancy sensors, modifying of the existing wiring to realize a switching in zones. The detection ranges of the adjacent occupancy sensors will be separated by attaching semi-circular covers on the detecting area to separate the zones among each other. Additionally each master detector, in other words each switch contact of an occupancy sensor, is to be protected with a snubber against parasitic voltage spikes and so as a consequence thereof against possible false switching. According to manufacturer's instruction the snubber is to be installed in close vicinity to the load, in other words the first light fixture. The snubbers must be mounted with all master occupancy sensors, also in the staircases. The existing retractive switches must also be removed, the cables isolated and the switch boxes covered with blind caps. Additionally to the installation and realization of the ceiling-mounted occupancy detector circuits all light fixtures must be checked for proper functioning. Defective light fixtures, ballasts, illuminants, etc. must be replaced, so that 100% functioning lighting system will be handed over after completion. A new emergency light system will additionally be installed in the buildings # 602, 628 and 683. To do so the ceilings must partly be removed for the laying of cables and inspection openings must be installed in the gypsum board ceilings. Not anymore required system parts of the old emergency lighting must be dismantled and disposed of. The three systems of the emergency lighting will be realized with self-contained emergency light fixtures with bus control and central monitoring unit of the individual batteries. The potential-free contact of the system for the general fault signal is to be applied to the EMCS as for the existing system. Three (3) different types of emergency light fixtures will be installed, EXIT light fixtures and LED-emergency light fixtures with and without heating for the outside area. Install the required undervoltage relays, ground fault circuit interrupters/circuit breakers, etc. in the existing subsidiary distribution boards and wire respectively to the demanded function. After completion of the work a proper operating emergency lighting with applied EMCS general fault signal per building shall be handed over. The contractor must move hindering items of furnishing must be moved out of the way and return them to the original position after completion of work. A fine cleaning of the respective surfaces must also be accomplished upon completion of work. All dismantled switches, covers, light fixtures, lines and electrical installation material has to be disposed of by the contractor. Emergency light fixtures still functioning and in a good condition, are to be turned in.
