Refreshing the NVM

If the user and/or engineer codes are lost, or you want to revert to the factory

default programming, then:

1. First remove mains power before opening the case and then discon-

necting the battery.

2. Identify and remove the NVM chip (IC4) on the main pcb (see Figure 1).

3. Reconnect the battery, then re-apply mains power.

4. Refit the NVM chip (note the locator marker position, see Figure 1).

The end station loads the factory default access codes (User 1: 1234,

engineer: 7890).

5. Carry on to re-program the system.

Testing

You may test parts of the system by entering commands at the keypad. To

carry out a test make sure the system is in programming mode and then key

in one of the following commands. Press Clear to end each test:

91 To test the external sounder/bell.

92 To test strobe output.

93 To test the internal sounder output.

94 To test the keypad sounder.

95 To test programmable output No. 1.

96 To test programmable output No. 2.

97 To carry out a system walk test. This allows the engineer to test all

alarm devices. When a circuit is opened, the internal sounder(s) will

emit a tone and the appropriate circuit LED lights.

Reading the Log

The control unit keeps a 60 event log of recent events. Each event is repre-

sented by a two digit code, shown on the next page. To review the event log,

make sure the system is in programming mode, then:

1. Key in 90.

The display shows the most recent event in the log, for example "c7".

For a list of the log codes see the next page.

2. Key in 1 to show earlier events or 3 to see more recent events.

3. Press Clear to leave the log.
