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 (P, 
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

 

(P, PowerMax GSM...)

 

To enroll the transmitters IDs to the P, 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.
