Sounder

During the setting period the sounder emits a continuous tone if all of the zones are closed. If a zone is opened during the setting period, the sounder begins to pulse. The sounder also pulses during the last 25% of the setting time to indicate time running short.

Zones Open

The exit time will reset should any zones be open or opened during setting. The display will indicate the number of zones open and invite viewing. Closing the zones will restart the exit time. An alarm will be generated if setting is not completed before the Fail to Set period ex- pires. (Fail to Set; programmed by engineer).

Note: Before closing the open zone, press esc to abort the setting routine. The ESC TO ABORT message will flash as a reminder.

Final Door/Terminator

The setting procedure can be manually completed by either closing the FINAL door or by pressing the TERMINATOR button.

System Set

When time has expired or a manual termination is made, the system waits four seconds before setting. The sounders emit two long tones to confirm that the system is set. The keypad briefly displays the message SYSTEM SET, before returning to the banner.

Part Setting

To Part Set the system press the < B key after the PIN. Only the zones which have the PART attribute enabled are set. All other setting features are the same.

Cancelling The Setting

The setting routine can be aborted by pressing the esc key before the system sets.

Group Name

Press * and # keys simultaneously when groups are displayed on the keypad (when setting for example), will display the name of the group . The group name should be programmed by the installation engineer. Press the * and # keys to return to the group display.
