DE3640 1 MCT-423 Supervised Wireless PowerCode Smoke Detector Installation Instructions 1. INSTALLATION SUMMARY 1.1 Disassembly A. Separate the unit from its mounting bracket as shown in Figure 1. Figure 1. Separating the MCT-423 from its Bracket B. Open the MCT-423 by pulling the cover away from the base at the point indicated by “OPEN HERE” in Figure 2. Figure 2. MCT-423 with Cover Swung Open 1.2 Setting the Function Switch The MCT-423 has a 4-position DIP switch function selector (see Figure 3). The switch levers are numbered 1 to 4, and each switch allows you to select one of two options. Open the cover and set the function switches as desired. The ON position is indicated by the arrow near the switch body. Table 1. Function selector settings Sw- Marking Pos. Selected Option Defaul t SW-1 LED ON OFF LED will light upon transmission LED is disabled ON SW-2 RESTOREON OFF “Restore” events reported “Restore” events not reported ON SW-3 TR-REP ON OFF Alarm reported every 3 min. Alarm reported only once OFF SW-4 BAT ON OFF Lithium battery is being used Alkaline battery is being used OFF Note: Transmissions initiated by “tamper” events will be repeated once every 3 minutes, regardless of SW-3 setting. Figure 3. Transmit Indicator and Function Switch 1.3 Battery Connection and Initial Test CAUTION: The MCT-423 comes with cover latches that will prevent the cover from closing if there is no battery inside. The smoke detector is supplied with a 9V alkaline battery seated within its holder but insulated from the battery terminals. A. Pull the battery out and peel off the insulating material to expose the terminals. B. Match the battery terminals with the flexible contacts on the detector PCB. Be sure to get the polarity right. If you reverse the [+] and [–], the battery will discharge completely within a very short time through the built in protection diode! C. When the terminals are properly matched, push the battery firmly in until it is seated tightly within the holder. Note: When the battery first makes contact with the detector, the alarm horn may sound for one second. This indicates that the battery is positioned properly. D. Close the cover, then press the test button for about 5 seconds until the horn sounds two sequences of a loud 3- beep alarm. This means that the smoke detection section is working properly. 1.4 Resetting the Transmitter Module and Enrolling its PowerCode ID A tamper protection switch is mounted on the transmitter board. The tamper actuator, extending through a hole in the base (see Figure 4), is pressed against the bracket when the unit is attached to the bracket. Removal of the unit from the bracket will cause the switch contacts to open, creating a tamper event, which will be reported by the transmitter to the control panel. Figure 4. Tamper Switch 2 DE3640 Besides its tamper protection role, the tamper switch is used to reset the transmitter at power up - this is important for proper function of the unit. To reset the transmitter and enroll its ID in the control panel’s memory, proceed as follows: A. Close the cover and turn the unit over, so that you can see the back of the base. B. Press the tamper switch once and release it. This will perform the reset necessary for smooth transmitter power-up. C. Refer to the control panel’s installation instructions and follow the procedure given there for enrolling transmitter IDs. When required to initiate a transmission for enrollment, press the smoke detector’s test button until the built-in horn sounds. Note: It is much easier to carry out this operation while holding the MCT-423 in your hand, close to the control panel. 1.5 Mounting the Bracket in Place Read Section 4 in this manual first, then decide where to install a detector. Refer to Figures 5 and 6 and proceed as follows: Figure 5. Aligning the Bracket Figure 6. Mounting the Bracket 1st.At the chosen location, draw a 15 cm (6”) long horizontal line. 2nd.Press the bracket against the mounting surface, aligning the two longest keyhole slots with the line drawn in Step A. Mark the drilling spots through two opposite keyhole slots. C. Drill two 5 mm (3/16”) holes at the marked spots. D. Attach the bracket to the wall, using the two screws and plastic wall anchors (supplied). 1.6 Final Assembly and Test 1st. Before attaching the detector unit to the bracket, it is a good practice to secure the cover to the base with two screws (supplied with the unit) through the holes shown in Figure 7. This will prevent unauthorized opening of the cover. DE3640 1 Note: Unauthorized removal of the unit from the bracket will initiate a tamper alert! Figure 7. Securing the Cover to the Base B. Press the test button until the built-in horn sounds. Verify that the transmitted signal has been received at the control panel, and that the control panel responds accordingly by activating the fire alarm siren or any other warning device. 3rd. Attach the detector to the bracket as shown in Figure 8. Pull outward to make sure that the detector is securely attached to the bracket. Figure 8. Final Assembly 2. DESCRIPTION AND APPLICATIONS The MCT-423 is photoelectric smoke detector designed to sense smoke, but not gas, heat or flame and fitted with a Power- Code- type UHF transmitter. It provides early warning of developing fire by sounding an alarm with its built-in alarm horn, and by transmitting a coded alarm signal to a PowerCode receiver or to a compatible wireless alarm control panel. It must be borne in mind, though, that effective pre-warning of fire accidents is only possible if the detector is located, installed and maintained properly as described in this manual. WARNING: This smoke detector is designed for use in a single residential unit only, which means that it should be used inside a single family home or apartment. It is not meant to be used in lobbies, hallways, basements or another apartment in multi-family buildings, unless there are already working detectors in each family unit.…
