The switch values are added together. These switches are factory set to a sensitivity of 24 counts per second, as shown in the example.
Example: | SW 4.1 | ON |
|
| SW 4.2 | ON | sensitivity |
| SW 4.3 | OFF | = 24 cps |
| SW 4.4 | OFF |

FIRE AREA VOTING SEQUENCE (not applicable to U1F)
SW 4.5, SW 4.6 and SW 4.8 select voting sequence which can be Fire Area 1 only (all detectors in one area) or Fire Area 1 separate from Fire Area 2. W hen separate, Fire Area 1 consists of detector 1 (1 and 2 for U4F) and Fire Area 2 consists of detector 2 (detector 3 and 4 for U4F). Switch SW 4.7 should be placed in the ‘OFF’ position at all times.
Fire Area 1 Separate from Fire Area 2:
<SW 4.7 OFF
<SW 4.8 ON
<SW 4.5 programs Fire Area 1 (detector 1 for U2F) (detectors 1 and 2
for U4F) |
|
OFF: | votes one of two detectors (always OFF for U2F) |
ON: | votes two of two detectors |
<SW 4.6 programs Fire Area 2 (detector 3 for U2F) (detectors 3 and 4 for U4F)
OFF:
ON:
Fire Area 1 only:
< | SW 4.8 | OFF |
|
< | SW 4.7 | OFF |
|
< | SW 4.6 | OFF |
|
< | SW 4.5 OFF: | votes any one of all detectors | |
|
| ON: | votes any two of all detectors |
RELAY OUTPUTS LATCHING/NON-LATCHING
The alarm relays are programmed together for latching or
< | 5.1: ON: | |
| OFF: | latching operation |
NOTE
Latched outputs are unlatched by activating the RESET switch.
RELAY OUTPUTS ENERGIZED/DE-ENERGIZED
The area and instant alarm relays can be programmed for normally energized or normally de- energized operation using SW 5.2 . The fault relay is always normally energized. SW 5.2 is factory set to
