Emerson 0016-00, UVC120 Relay Outputs LATCHING/NON-LATCHING, Relay Outputs ENERGIZED/DE-ENERGIZED

votes one of two detectors (always OFF for U2F) votes two of two detectors

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 non-latching operation (the fault relay is only non-latching).

<	5.1: ON:	non-latching operation
	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 de-energized operation (ON)
