Finder announces a new generation of its 14 Series electronic staircase timers, which have been designed for energy saving control of lighting in areas of temporary occupation. The latest models feature microprocessor control, and are targeted at lighting applications in stairwells, corridors, washrooms, storerooms and similar areas that only require illumination for short periods of time.

Designers, contractors and installers of lighting in commercial and residential property are continually looking for ways to reduce energy consumption by eliminating wasteful lighting in unoccupied areas, while addressing the growing need to illuminate more public areas for security and safety reasons in an economical way. Staircase timers such as the 14 series offer a cost-effective solution that is simple to implement even in small installations.

The 14.01 timer is a multi-function unit, while the 14.71 is a single function version. Both models have an on period that is adjustable between 30s and 20 minutes, so that a single timer is suitable for wide range of installations. This flexibility of operation means that specification is simplified and inventory levels can be kept to a minimum. A further single function model, 14.81, offers wiring compatibility with earlier mechanical models.

All the new timers feature zero-crossing load switching, which enables the switching of higher lamp loads and also offers the benefits of longer lamp and unit life and reduced RF interference. A switch-off early warning function on the 14.01 gives a user who is still in the area time to re-activate the timer before the light is turned off.

Multi-function features on the 14.01, accessed via a simple rotary function selector, include timed control with or without manual override, early warning, standard on/off, permanent on and maintenance function with extended 60 minute on time.

Each timer can be used with up to 30 illuminated pushbutton actuators, offering local control over a wide area and thus giving the user maximum opportunity to re-activate the timer before being plunged into darkness: this enhances safety, and is especially beneficial in stairwells.

All the 14 Series timers are housed in a 35mm rail mounting enclosure that is 17.5mm wide, and have a timing adjustment suitable for standard consumer unit.

The 4C Series is a new series of single-pole and two-pole relay interface modules from Finder that incorporate Finder’s flagship 46 Series miniature industrial relays, and are available in either screw terminal or screwless socket types. The modules provide an ideal interface between programmable logic controllers (PLC) or other electronic controllers and external actuators or switching devices, where outputs are required to switch higher than normal external loads such as large contactors, solenoids, small motors or heating elements.

The 4C.01 and 4C.02 are respectively a single-pole 16A and a two-pole 8A relay interface module, both with screw terminal connections, while the 4C.51 is a screwless single-pole model rated as 10A and the 4C.52 is an 8A two-pole screwless version. All four models are available with either AC or DC coils, and can be mounted on a 35mm DIN rail (EN 50022). They feature instant ejection of the relay from the socket by means of a plastic retaining clip, and include as standard both a supply status indication and coil suppression module.

An 8-way jumper link is available as an optional extra for use with the 4C.01 and 4C.02 modules, and reduces the time taken to wire common connections.

The 4C.01 and 4C.02 screw-type terminal modules both measure 82.9mm long x 64.6mm high x 15.8 mm wide, while the screwless 4C.51 and 4C.52 versions both measure 95.6mm long x 61.7 mm high x 15.8 mm wide. The cadmium-free relay contacts are fabricated from silver nickel (AgNi) material.

Finder introduces the 72.31 three-phase monitoring relay, which is used for detecting a loss of phase or incorrect phase rotation when using three-phase supplies. This compact relay is ideally suited for the protection of motors in plant and machinery, and helps to satisfy the mandatory requirement of ensuring the correct rotation of motors in transportable equipment.

The 72.31 allows OEMs, panel builders and installers of control systems to ensure that motors do not become permanently damaged due to phase loss, and also to avoid potential hazards or damage due to incorrect rotation of the motors. The relay features positive safety logic, which triggers the contact to open if an error is detected so that the system will fail to a safe condition. The wide supply voltage specification allows a single unit to be used across the full three-phase supply voltage range of 208V to 480V AC.

The relay provides reliable monitoring of phase loss, even under conditions where the lost phase may be “regenerated” by the action of the rotating motor. This phenomenon is not uncommon, and many monitoring relay units that are currently available may falsely detect this phase regeneration and thus fail to disconnect the supply, which can cause damage to the motor. The 72.31 can discriminate phase regeneration up to 80% of the line voltage.

Featuring a SPDT output contact rated at 6A (maximum peak 15A), the 72.31 monitoring relay is enclosed in a compact housing measuring 84mm high x 56.5mm deep x 17.5mm wide. The narrow profile offers considerable saving in panel space.

The 18 Series of PIR movement detectors from Finder has been extended to include a new model that operates outdoors in addition to the existing indoor model. The units detect body heat to control lighting in a range of applications, including energy saving and security.

The detectors can reduce energy consumption by automatically switching off lighting when it is not required. This addresses the increasing pressure on companies from both governments and environmental groups to reduce energy consumption, which means that areas of unnecessary lighting have come under scrutiny.  In parallel to this, there is a need for improved lighting particularly in exterior areas to deter potential intruders.

Finder’s PIR detectors are targeted at designers, engineers, contractors and installers of lighting control systems in commercial, industrial and domestic premises.  They will be of particular use in areas inside and outside buildings that are not permanently occupied, such as offices, washrooms, corridors, stairwells and stores as well as outside loading bays, access ramps, etc. where constant lighting is not required.

The output contact for both the 18.01 interior model and the 18.11 exterior model is rated at 10A, with a 20A peak current capability, suitable for switching a 230V incandescent or halogen lighting load of up to 1kW or a compensated fluorescent lighting load rated at up to 350W.

The coverage area spans 110° in both the vertical and the horizontal plane, and the sensing range is specified up to 8m. An integral adjustable threshold light sensor ensures that energy is not wasted by preventing the lights from being switched on in conditions of high ambient light.

To avoid accidentally switching off lights when personnel are still in the lighting zone, the Series 18 PIR units feature an extended ‘on time’. This enables the length of time the lights remain on after movement detection ceases to be extended by a preset delay time, which can be adjusted to between 10 and 180 seconds.

The versatile design of both Series 18 PIR models features a ball joint construction that enables simple, trouble free mounting on a flat vertical or horizontal surface, with the ability to angle the detection head to adjust the required detection area by up to 180° in the horizontal plane, and 27° in the vertical plane.

The 18.01 model allows concealed cable entry via the mounting bracket, while the IP54 protected 18.11 exterior model features a PG9 cable gland entry in the base. The electrical contacts are lead-free AgSnO2.

The Series 18 PIR range is entirely designed and manufactured in-house at Finder’s European facility near Turin in Italy. The design includes custom embedded system programming, CAD evolved optics, custom designed electronics, tooling and test equipment.  The units are competitively priced and offer specifiers and end users a European designed and built PIR with unparalleled flexibility, in a neat and compact housing.
