DE2411U 1 MCT/IR-252 WP S Resettable Dual RF & IR Waterproof Transmitter User Guide 1. INTRODUCTIONThe MCT/IR-252 WP S is a miniature, water-proof, resettable, microprocessor controlled, personal transmitter designed for use in the SpiderAlert signaling network. The transmitter has two buttons, used for reporting three different events: Panic (large button), Assist (small button) User Defined (by clicking on the two buttons simultaneously). The alarm events are supposed to be acknowledged and reset by the person who responds to the alarm message by holding a magnet close to the pendant. In the case that an event is not acknowledged, a No Response message is sent. In addition to the above-mentioned events, the transmitter also sends low-battery, tracking and supervision messages (when defined in DIP switch). The transmitter transmits coded UHF signals and pulsed infrared signals simultaneously, thereby allowing the target receiver to accurately determine the specific point at which transmission took place in multi-storey buildings. Besides the regular alert mode, in which an alert message is transmitted only once, the transmitter can be set to two additional modes – MESSAGE CYCLE and REPEATED MESSAGE CYCLING. In the message cycle mode, panic, and assist messages are automatically repeated three times, and a no-response message follows if the message has not been acknowledged. In the cycle repetition mode, a sequence of three alarm messages followed by a no-response message (one cycle) is repeated 5 times, unless the message is acknowledged sooner. The time interval between these messages is determined by the DIP switches (para. 3.1). When a Panic message is transmitted after an Assist message has been initiated, the repeated messages will be Panic messages instead of Assist messages. When holding an external magnet close to the unit, either from underneath or on top, near where the pushbuttons are positioned (fig. 1) the repetitive message transmissions will stop and an acknowledge message will be sent. Fig. 1 – Resetting Transmitter Once the button is depressed, the LED lights and after approximately one second the message is transmitted. It is important not to cover the LED during the period of time after pressing the button.

There are over 16 million code possibilities, so for all practical purposes no two transmitters will have the same ID code. The dual-technology alert transmissions made by the MCT/IR-252 WP S are directed at SpiderAlert receivers. These receivers are strategically located all over the surveillance area, to pick up alert transmissions and report the ID code of the transmitter whose signal was picked up. SpiderAlert systemSLC-5UPSControllerPCSR-520RF+IRreceiverSpiderBusMCT/IR-252 WP S Figure 3 – Application Configuration Reporting is accomplished via a two-wire bus routed to the SpiderAlert Local Control Unit SLC-5, that collects and transfers all data to the SpiderAlert main computer automatically displaying the holder’s name and exact location. All units are supplied with a chain, to be worn around the neck as a pendant transmitter. 2. SPECIFICATIONSFrequency (MHz): 315 or 868.

MAINTENANCE AND TESTING 4.1 Battery Installation A. Place a coin in the slot of the battery cover. B. Turn the coin anti clockwise as far as you can. Figure 4 – Placing Coin C. The cover will become slightly raised. D. Remove the cover. E. Take out the battery and position the new battery with the positive (+) side up. F. Reposition the battery cover. RAISED BATTERYCOVER Figure 5 – Removing Battery Cover G. Place a coin in the slot of the battery cover and turn clockwise as far as you can until you hear a click confirming closure. 4.2 Testing A. Stand 3 m (10 ft) away from the receiver and hold the transmitter with its two infrared LEDs directed at the receiver. Make sure your fingers stay clear of the infrared LEDs. B. Depress the transmit pushbutton and verify that the transmitter's indicator LED lights. IMPORTANT! The user should be warned that the infrared (IR) signal will be transmitted only if the infrared LEDs are kept exposed, free to radiate into the surrounding space. Infrared radiation will be blocked if the transmitter is cupped in the palm of the hand or if transmission is attempted from a pocketed transmitter. Whenever the infrared source is blocked, the SpiderAlert network will have to rely on radio signal only, with lesser accuracy in locating the transmitting unit. C. Observe that the receiver LED responds to detection: receiver's indicator LED should light steadily if only the RF signal is captured, but should flash if both RF and IR signals are captured. D. Verify that the ID code of the transmitter in use has been registered by the SpiderAlert head-end computer. E. Operate the transmitter from various locations within the area covered by the receiver to determine "dead" spots, where transmission may be obstructed by walls and large objects, or affected by structural materials. 5. MISCELLANEOUS COMMENTS 5.1 Comments on IR Signaling Attaining the maximum IR reception range depends mainly on direct line of sight between the transmitter and the receiver. Nevertheless, certain environments allow the signal to reach the receiver in a roundabout path, by reflection or refraction of the infrared radiation. Tiled floors (uncarpeted), walls, smooth ceilings (not too high) can reflect IR signals reasonably well, allowing them to be received even when the radiating source is pointed away from the receiver. With good indirect reflection path, a range of 5 - 6 m (15 - 18 ft) is expected (with poor reflection, the range gets even shorter). The user is therefore strongly advised to point the transmitter directly at the nearest receiver or, if the location of the nearest receiver is unknown, to press the transmit button several times while pointing the transmitter in different directions. It is strongly recommended not install IR receiver outdoors, facing direct sunlight, or near fluorescent lamps, to prevent interference to IR reception. The installer is encouraged to test the reception range in the various zones and to install additional receivers if necessary. 5.2 Comments on Radio Signaling Some limitations have to be considered. A. Receivers may be blocked by radio signals occurring on or near their operating frequencies, regardless of the code selected. B. A receiver can only respond to one transmitted signal at a time. C. Wireless equipment should be tested regularly (at least once a week) to determine if there are sources of interference and to protect against faults. Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 5.3 Compliance with Standards The digital circuit of this device has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in residential installations.This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio and television reception. However, there is no guarantee that interference will not occur in a particular installation. If this device does cause interference which may be verified by turning the device off and on, the user is encouraged to eliminate interference by one or more of the following measures: • Re-orient or re-locate the receiving antenna. • Increase the distance between the device and the receiver. • Connect the device to an outlet on a circuit different from the one which supplies power to the receiver. • Consult the dealer or an experienced radio/ TV technician.
