14.3 Programming Zone Delays

The 3300 can have a delay programmed on one or more of its detector zones. When a zone delay is

programmed, a fixed time delay ( 0 to 10 minutes ) is given from activation of that zone to activation of

the alarm outputs / global fire relay and fire link output ( if fitted ). However a manual call point

activation on a delayed zone will override the delay.

The delay time is set up by adjusting a potentiometer ( VR1 ) on centre of the Main PCB, See

appendix 4 for the location of the potentiometer.

If the ‘Silence Alarms’ button is pressed while a delay is running, the alarm outputs will not be

activated when the delay expires. The global fire contacts, however, will still be activated.

Note:

• The delay time applies to ALL zones programmed with delays.

• The exact delay time should be verified during commissioning, and noted on the system set-up

record in the 3300 user manual.

The procedure for programming a zone delay is given below.

1. From access level 1 enter the 5 digit engineer code 1 3 4 2 4. The ‘Supply Present’ indicator

will flash indicating level 3 has been accessed and all programming features are available.

2. Scroll to the ‘Output Delay’ indicator by repeatedly pressing button 2. Any currently programmed

zone delays will be displayed on row 1 of the display. Accept the option by pressing button 3.

3. The ‘Output Delay’ indicator will flash, to indicate this option has been accepted.

4. Scroll to the detector zone to be delayed by pressing button 2.

5. Press button 1 to set delayed / not-delayed for that zone. The row 1 indicator will be illuminated

when the zone is delayed.

6. Press button 3 to return to the selection menu.

7. Press button 4 to accept and program the delayed zones and return to access level 2.

The yellow ‘Output Delay’ indicator will be illuminated steady, showing that at least one zone (or the

fire link interface, if fitted) has a delay programmed.
