MCT-423

Supervised Wireless PowerCode Smoke Detector

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.

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.

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.

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.

Note: Unauthorized removal of the unit from the bracket will initiate a tamper alert! 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 Figure 7. Securing the Cover to the Base B.

. SMOKE DETECTOR INSTALLATION OVERVIEW 4.1 Where to Install Smoke Detectors Smoke detectors should be installed in accordance with the NFPA Standard 74 (National Fire Protection Association, Batterymarch Park, Quincy, MA 02169). For complete coverage in residential units, smoke detectors should be installed in all rooms, halls, storage areas, basements and attics in each family living unit. Minimum coverage is one detector on each floor and one in each sleeping area.

recommend complete coverage and use of additional smoke detectors. 4.2 Where to Install Smoke Detectors in Mobile Homes and RVs Mobile homes and RVs built after about 1978 were designed and insulated to be energy-efficient. In mobile homes and RVs built after 1978, smoke detectors should be installed as described above. Older mobile homes and RVs may have little or no insulation compared to current standards.

F. Close the cover, re-insert the screws, and test the unit as instructed in Para. 1.6B. G. Re-insert the screws, tighten them well and re-mount the unit on the bracket as instructed in Para. 1.6C. 5.2 Cleaning Open the cover and vacuum the dust off the detector's sensing chamber at least once a year. This can be done when you open the detector to change the battery. Remove the battery before cleaning. Use the soft brush attachment to your vacuum cleaner.
