MCT-430

Supervised Wireless PowerCode Smoke Detector

Installation Instructions

1. INSTALLATION SUMMARY

1.1 General Description

The MCT-430 is a low profile, battery operated, photoelectric

smoke detector which shares its housing with a UHF PowerCode

type transmitter. It has a 57°C (135°F) fixed temperature heat

detector and a built-in sounder. The detector sends out the

following messages to the control panel:

• Smoke alarm

• Heat alarm

• Tamper alert

• Low battery alert

• Trouble message (when heat sensor malfunctions)

• Service alert (degraded smoke detection sensitivity - internal

screen requires cleaning).

During normal and low battery conditions, the LED flashes

approximately once every 40 seconds. The smoke/heat detector

will sound its built-in temporal horn when smoke activates the

detector (the LED flashes rapidly), or when the air temperature

reaches 57°C (135°F). A message is also sent to the wireless

control panel. After the horn stops, a RESTORE message is

transmitted to the control panel and the ID number can be

cleared from the panel. The built-in Drift Compensation algorithm

automatically maintains the sensitivity of the detector. Once the

detector reaches its limit of compensation, it transmits a

maintenance signal to the panel. When maintenance is required,

the LED stops flashing.

The maintenance signal fully complies with the sensitivity test

requirement specified in NFPA 72, 7 - 2.2.

1.2 Power Up and Initial Test

The smoke detector is supplied with two 3V batteries seated

within their holder but insulated from the battery terminals.

A. Turn the detector upside down and pull out the paper tab that

insulates the batteries from one of the terminals.

B. Insert a sharp object into the test switch hole and push the

switch in continuously, until the built-in horn sounds (about

2.5 seconds after depressing the button). The sounding

sequence is: 3 beeps - short break - 3 beeps ......and so on

until you release the switch. In addition, the LED will flash

rapidly a few times. This means that the smoke detection

section is working properly.

1.3 Enrolling Transmitter’s Power- Code ID

The detector includes a tamper switch that causes a tamper alert

when the main body is separated from its mounting bracket. This

switch protects the unit against unauthorized handling.

The detector has two separate PowerCode IDs:

• The first ID is linked to messages containing alarm, low

battery and supervision data.

• The second ID is linked to messages containing tamper and

maintenance data such as “clean” and circuit trouble.

Enrolling process to the PowerMax is differennt from the enrolling

process to other versions of the PowerMax (PowerMax+,

PowerMax GSM....), as described in par. 1.3.1 and 1.3.2.

1.3.1 Enrolling to PowerMax Control Panel

It is necessary that the control panel will learn the two IDs before

the detector is actually mounted in place. This is best carried out

in close proximity to the control panel. Each ID must be enrolled

to a separate zone of the control panel.

A. Refer to the control panel’s installation instructions and follow

the procedure given there for enrolling transmitter IDs in the

control panel's memory.

2nd. When required to initiate a transmission for enrollment of

the first ID, activate the test switch (see fig. 1) until the built-

in horn sounds (see Para. 1.2B).

C. When you are instructed to initiate a transmission for

enrollment of the second ID, separate the detector from the

bracket to activate a tamper message.

Important: If the second ID is not learnt by the control panel,

the maintenance and tamper messages will not be received.

Note: The PowerMax control panel can not distinguish

between “clean” and circuit trouble data. Upon receiving a

maintenance alert, clean the internal screen as described in

Para. 5.2. If the maintenance alert persists, the trouble is

probably due to a circuit failure.

1.3.2 Enrolling to Other Versions of PowerMax

(PowerMax+, PowerMax GSM...)

To enroll the transmitters IDs to the PowerMax+, PowerMax GSM

and above, it is necessary to enrol only one ID, the first ID or the

second ID (for IDs description refer to par. 1.3). When either ID

is enrolled to one zone, the second ID is automatically enrolled.

The enrolling process is as follows:

A. Refer to the control panel’s installation instructions and follow

the procedure given there for enrolling transmitter IDs in the

control panel's memory.

2nd. When you are instructed to initiate a transmission for

enrollment of the ID, activate the test switch until the built-in

horn sounds (see Para. 1.2B), or separate the detector from

the bracket to activate a tamper message.

1.4 Mounting the Bracket in Place

Read Section 4 in this manual first, then decide where to install

the detector. Refer to Figure 2 and proceed according to the

following instructions.

1st.If the detector is attached to the bracket, separate it from the bracket by holding the bracket in one hand and turning the detector slightly counterclockwise with your other hand. Note: Removal of the unit from the bracket will initiate a tamper alert! The LED will flash but the horn will remain silent. 2nd.Press the bracket against the mounting surface and mark the drilling spots through two mounting screw bays. C. Drill two 5 mm (3/16”) holes at the marked spots. D.

WARNING: Never remove batteries to stop a nuisance alarm. Open a window or fan the air around the detector to get rid of the smoke. The alarm will turn itself off when the smoke is gone. If nuisance alarms persist, attempt to clean the detector as described in this manual. WARNING: Do not stand close to the detector when the alarm is sounding. The alarm is loud in order to wake you in an emergency. Too much exposure to the horn at close range may be harmful to your hearing. 4.

F. Remove the sensing chamber cover. G. Clean the sensing chamber by vacuuming or blowing out dust and particles. H. Replace the sensing chamber cover, aligning the arrow on the cover top with the arrow on the printed circuit board. I. Replace the screen by placing the screen assembly over the sensing chamber cover and twisting until it snaps into place. J. Replace the housing by aligning the two triangular slots on the base with their counterparts on the housing.
