1 1. Introduction The Remote alarm Panel, TYPE RAPv2 The microprocessor based remote monitor from Metron Eledyne is the latest version of a whole line of successful products, marketed previously under the Eledyne Ltd name, and features state-of-the art micro-controller devices, designed around the latest EEC EMC directives. The unit offers a compact, robust and reliable product, offering a great deal more flexibility than its predecessors. It features 16 channel monitoring, designed primarily for use with the Metron Eledyne range of fire pump control panel, providing remote supervision of complete installations from any manned point, (for example; gate houses and reception points). The unit may be tailored to individual requirements both quickly and easily by our team of dedicated software engineers using our unique software-based control system. Component choice has been heavily influenced by the need to meet tough EMC requirements, providing both excellent immunity and reduced emissions. ew features in this model include four DIP switches enabling banks of four inputs to be configured on site for normally closed or normally open operation, smaller footprint, and more attractively packaged in a style that will blend into most environments without being intrusive, yet impossible to ignore when an alarm state is triggered. Experience has also shown the need for flexibility. Achieving this is aided by the fact that the control system is entirely software dependent, a complete change in system behaviour is merely a case of programming a non volatile memory device, a matter of seconds in most cases, ensuring that down-time is kept to an absolute minimum, essential in fire control applications. As part of this flexibility, it was also realised that there may be a need for rapid re-allocation of channels, normally a lengthy process, requiring both a rewire, and then producing the correct front panel legend. As most good ideas are both flexible and simple we needed to adopt an approach whereby the customer could complete this task with ease. It was decided to utilise a removable channel allocation label. The label may be re-printed to order; alternatively the customer may decide to legend the panel themselves on site. 2. Basic peration peration of the RAPv2 is relatively straight forward and all functions are accessed via the three push buttons on the front panel. When power is first applied two indicators should immediately come on regardless of the state of the inputs. The green power on indicator located on the front panel shows that the +5v logic supply is healthy, and an internal green indicator located on the main board type PC264 shows that the +12v dirty supply is available. When an alarm state is registered, the corresponding indicator will flash, and an alarm will sound. urther alarm states will also cause the corresponding indicator to flash in addition. MUTE push button; Silences any alarm, flashing indicators become steady. urther alarm states will Page: 1 Metron Eledyne peration Manual, P-RAPv2, ver 1.1, 25/9/2011 for remote alarm panel type RAPv2

2 re-trigger the audible alarm, and while the muted channels remain steady, the new alarm state will cause only the corresponding indicator to flash. RESET push button; All channels which are no longer in the alarm state will reset, i.e the indicator will extinguish. Providing there are no channels in the alarm state, the audible alarm will remain silent. Any channel which remains in the alarm state will re-trigger the audible alarm, and return to a flashing state. LAMP TEST; Pressing this push-button will cause the unit to perform a lamp test function. General Arrangement: REMTE ALARM PAEL PWER MUTE RESET LAMP TEST Page: 2 3. Installation Guide The RAPv2 has been designed primarily for simplicity of installation and ease of use. The unit fully complies with the EMC criteria as specified in the European Directive. Compliance does not, however, cover the final installation of the product. Installation in itself is a reasonably straight forward task, capable of being carried out by relatively inexperienced staff, but it must be stressed that it is the responsibility of the installing engineer to follow E.M.C guidelines as laid down in the E.E.C Directive. irst, remove the two screws securing the front panel to the enclosure, and carefully allow the front plate to swing downwards using the piano hinge. With the front panel down, the main connections are on the P.C.B via screw terminals. (These are push-in plugs, to facilitate easy removal / replacement of the main board). The mains connector is designated PL3, and is a four way plug. Two connections are for earth, the other two are live and neutral. use 3 is the mains protection fuse, and should only be replaced by the same rated part. All inputs are set as default to normally closed, and should any conductor become disconnected, will fault to the alarm state. (Banks of 4 may be switched to normally open via dip switch settings - see section 4, set up). All input circuits are rated at 12V d.c maximum. All unused channels should be loomed together along with the GD connection, or alternatively switched to normally open inputs.

3 If option A(battery Back up option) is fitted, then ensure that the isolation switch is turned to the position when ready to initialise. The cabinet should be specifically earthed, using the external earth bolt provided. TE: It is highly recommended, although not essential, that the following recommendations are considered. All signal wiring should be separated from power feeds and supplies. Where the two must be in close proximity, it is advisable that they located at right angles to each other, minimising the effect of cross-talk and pick-up. Signal wiring will be less prone to disturbances if contained within grounded conductive conduit or trunking. Avoid passing signal cables in close proximity to known interference sources, or high power electrical equipment where possible. Ensure good clean areas of contact at either end of the installation, and use the largest practical gauge of wire to improve signal quality, (maximum 2.5mm diameter cable recommended). Loop areas of all conductors should be kept to a minimum, as each loop will act as an antenna for radio-interference, and will significantly reduce the immunity of the whole installation. The enclosure should be earthed with good quality earthing bonds. Avoid earth loops. The enclosure should be mounted in dry environment so that the enclosure is not exposed to moisture. 3.1 Remote Common ault utput This control panel is equipped with a dedicated common fault volt free output. This is intended to be used as a single common repeat output which changes over if AY channel is in the fault state. The relay contacts are rated at 1Amp maximum. This output is available on PL19, see schematic diagram for pin outs. Page: 3 Metron Eledyne peration Manual, P-RAPv2, ver 1.1, 25/9/2011 for remote alarm panel type RAPv2

4 4. Set Up The DIP switches are located on the main P.C.B type PC264) inside the enclosure. These allow the installing engineer to change the polarity of the alarm signals from / to /C or vice-versa. Each setting controls a bank of four channels at a time. The following table shows the various combinations; SW1 SW2 CHAEL o = ormally closed 1= ormally open Dip switch Diagram: The DIP switch in the position, means normally open inputs.

5 ption A, Battery Back up This option includes additional hardware to provide the remote alarm unit with a battery back up feature. In the event of a total mains supply failure the battery will provide power so that the remote alarm panel can continue operating for a period of time. This option also includes an integral battery charger to fully and automatically recharge the battery once the mains supply is restored. This battery charger will charge a battery from a fully discharged state, in around 24 hours. The maximum output of the charger is 330mA. The battery provided is a high specification gel type battery that does not require any maintenance. However, it is recommended that the battery is T left in a fully discharged state for great periods of time. If the AC is intended to be off for an extended period then please isolate the battery using the switch provided. The battery charger control board also includes an isolating switch which enables the user to disconnect the battery from the charger. The remote alarm panel is shipped from Metron Eledyne Ltd with the switch in the off position to ensure that the alarm does not operate during shipment. To put the remote alarm panel into service, simply slide the switch SW1 to the on position (fully left) and then the power will be applied. The charger board, type PC251 contains a green indicator, which illuminates when the charger is on and should always be on while the AC supply is present. There are also two fuses and should only be replaced with the same rated part. 1 is the input protection for the charger, and 2 is an additional battery output DC protection fuse. Current Consumption: The amount of time that the battery will maintain a power source to remote alarm panel depends on the number of channels active. The standby current drain (no channels active) is only 35mA, and the battery is 7.5A/hr. If we assume the battery is 90% efficient, then (7.5Ahr x 0.9 efficient )/ 0.035A drain = 192 hours standby time. The above chart shows the current drain, by the number of channels in each state, alarm on and muted. (with no relay repeater board, option B) Page: 5 Metron Eledyne peration Manual, P-RAPv2, ver 1.1, 25/9/2011 for remote alarm panel type RAPv2

6 We can see if all 16 channels are active then the drain is 275mA, then: (7.5Ahr x 0.9 efficient)/ 0.275A gives only 24 hours standby. When the battery is approaching its fully discharged state, the processor will shut itself down leaving the indicators in the state they were prior to shutdown. The indicators will continue to glow, but getting dimmer in brightness proportional to the state of the battery. nce the mains is restored the processor will self reset and continue to operate normally. If the battery is fully discharged, and has been so for some time, then it may take a few seconds for the processor to self reset once the mains is restored. It is recommended from time to time, that the battery charger and battery is exercised periodically by removing the AC supply for 1 hour at a time. This action will extend the batteries life expectancy and enable it to maintain a high efficiency. ption B, Repeat Alarm utput This option provides 16 relays to repeat all 16 channels onwards to another device. The relays are provided with the common change over point connected together in banks of 4. All relays are rated at 125V DC, 1 Amp maximum. Please see schematic diagram for pin outs and connection points. The relay outputs follow the input contact state directly, and no logic sequence applied. The drawing is shown in the powered up state, with the input contacts closed.
