ProSYS Installation and Programming Manual

NOTES:
The total power from the
AUX
terminals should not exceed 600mA.
To connect a 4-wire smoke detector or devices that require resetting after an alarm condition,
connect the Auxiliary power
AUX
and UO terminals (refer to Figure 4 on page 18, for smoke
detector wiring). Remember to define the UO as Switched Auxiliary (refer to the
Switch AUX
parameter described in
Chapter 5, Quick Key [3][1][14]
).
Using the Installer Programming
Menus
).
In addition, when connecting a 4-wire smoke detector, observe the wiring guidelines mentioned
in the previous sections, along with any local requirements applicable to smoke detectors.
To prevent a possible drop in voltage due to current requirements and distances involved,
make sure to use the appropriate wire gauge (refer to the table of gauge sizes
in
Chapter 1,
Introducing ProSYS
).
To increase your power supply when employing multiple auxiliary devices, you can use the
optional Power Supply expansion module (refer to the
Wiring Power Supply Expansion
Modules
section in
Chapter 3
,
Installing External Modules and Devices
).
If the auxiliary outputs are overloaded (exceed 600mA) and are shut down, you must
disconnect all loads from the outputs for a period of at least 10 seconds before you reconnect
any load to the auxiliary outputs.
Wiring the Bell Sounders
To wire the bell sounders:
1
Connect a suitable wire to the internal sounding device(s) inside the building (bell, electronic
siren, or loudspeaker).
2
Ensure that you note the polarity when connecting electronic siren(s) and/or polarized bells.
!
WARNING:
To avoid Bell Loop Trouble, if
NO
connection is made to an internal sounder, use a 2200
Ω
resistor in its place.
NOTE:
It is important to position the
BELL/LS Jumper (J3)
correctly. The position varies depending
on the type of internal sounder.
3
For a loudspeaker without a built-in sound driver, position the jumper J3 so that it covers both
pins. The Main Panel produces a continuous oscillating voltage for burglary and panic alarms
and an interrupted oscillating voltage for fire alarms.
4
For a bell or an electronic siren with a built-in sound driver, position the jumper J3 so that it
does NOT cover both pins. A steady 12V DC is produced at the sounder terminals during
burglary and panic alarms. A slow pulsing voltage is produced during a fire alarm.
Wiring the Bell Tamper
To wire the bell tamper:
Connect the bell tamper to the
BELL TMP
and
COM
terminals on the Main Panel, as
illustrated in
Figure 4: Main Panel Wiring Diagram
on page 18.
