Water Flow Zone: This is a zone programmed to

operate like a Fire Zone, but is specifically intended for

water flow switches.

• An optional retard timer can be programmed to

compensate for changes in water pressure. If the

timer is used, the water flow zone must be activated

for the complete time period; an alarm will be

initiated at the end of the timer period.

• The maximum combined water flow delay of the

control panel and the device must not exceed two

minutes.

Any zone can be a water flow zone, but

only zones 1 through 4 may be

programmed as delayed water flow zones.

Supervisory Zone: This is a zone programmed to

accommodate shut-off valves.

• It will indicate a supervisory condition at the

keypads when activated.

7.2.3 Zone Programming

Zone: A Zone is an input to the DS7400Xi

Control/Communicator.

• There are eight hardwired zones on the main circuit

board.

• Additional zones may be added by using the

DS7433 (8 zone expansion module), the DS7430

(multiplex loop module), and/or other modules.

Single Zone Input: This is an individual zone such as

the on-board zones and multiplex contact zones.

Multiple Zone Input: This is a zone connected to one

of the 8-Input Modules (DS7432E or DS7433) or to a

Dual Zone Module (DS7460i).

• The inputs are programmed separately (see the

separate Programming Addresses Worksheet, P/N:

29802).

• When using the Dual Zone Module (DS7460), loop

A is always programmed as an odd numbered

program address (ending in 1, 3, 5, 7, or 9). Loop B

is the even numbered program address that follows

loop A.

DS7465i: This is the input zone or the output relay on a

DS7465i. The odd numbered zone is programmed for

the input zone function and the even numbered zone is

programmed for the output function.

Multiplex Smoke: This is a multiplexed input zone

(zones 9-248) that is used with a MX250 or MX280

series smoke detector. This zone must have a Zone

Function of Fire Zone and Trouble on Open applied

to the multiplex smoke zone.

Smoke alarm: This must be the odd-numbered zone

of the zone pair required for these devices. The zone

must be programmed with a zone function that is set

for Fire Zone and Trouble on Open.

7.2.4 Output Programming

Latch on Any Zone Alarm: This is an output

programmed to activate upon any zone alarm

(including invisible zones) and will latch until the

system has been disarmed.

• If this output is programmed to respond only to a

fire zone, it will remain latched until the fire reset

command is performed.

ON during Entry Pre-Alert: This is an output

programmed to activate when an entry/exit zone is

violated while the system is armed.

• It will remain activated until the system is

disarmed, or until the entry delay time has

expired.

ON for 10 seconds after [PIN][System Reset] is

entered: This is an output programmed to activate for

10 seconds after the fire reset command is entered at

the keypad or if a Fire Zone with Verification

activates.

• This output is intended to be used to power 4-wire

smoke detectors or any other device that requires

a power interruption to reset an alarm condition.

When Programmable Output 2 is

programmed this way, it will normally

supply auxiliary power and will turn OFF for

10 seconds when the fire reset command

is entered.

ON when System is Armed: This is an output

programmed to activate when the system is armed.

• It will remain activated until the system is

disarmed.
