2-3.2 Programmable Output Wiring
Programmable outputs (PGMs) are available directly
from the system panel or from the NT9204 module.
When activated, the output will switch to ground.
PGM outputs can be programmed in any of the
options listed in section [009] and can be customized
using up to 8 attributes, see section [141].
☞
PGMs 3 through 10 are not supported at this
time.
PGMs 1, 2 - PGM 1 and 2 can sink 50 mA. This out-
put can drive an LED indicator or small buzzer directly.
Connect Y1 (PGM 1) or G2 (PGM 2) to the negative (-
) terminal of the device and connect the positive ter-
minal of the device to the R terminal. If current greater
than 50 mA, or voltage greater than 6 V
DC
is required
for an application then a relay must be used.
PGM 1 and PGM 2 - are programmed in section
[009], output attributes are programmed in section
[141] and [142].
PGMs 11, 12, 13, 14 - The NT9204 provides 4 high
current (1.0 Amp) programmable outputs that sink
outputs to a 12 V
DC
supply. These PGMs are pro-
grammed in section [011]; output attributes are pro-
grammed in sections [151] – [154].
2-3.3 Hardwired Zones
Two hardwired zones are available in three configura-
tions. Only one configuration can be selected for both
zones, and each must be wired according to the
selected configuration. The Y1 terminal is Zone 1 and
the G2 terminal is Zone 2. The B Terminal is common
for both zones. All wiring is connected between the
appropriate zone terminal and ‘B’ (common). To
enable this option, section [018] option 1 must be OFF
(default).
☞
The default setup is for single EOL resistors.
These zones can be assigned to any zone number
through Flash Programming or Advanced Program-
ming (section [030]). Zone loop response time is pro-
grammed in section [ 031] (default = 500 ms).
☞
Entering [00] in section [030] will configure
the associated terminal as a PGM output. To
configure the terminal as a zone, [01]-[32]
must be entered.
Enroll the Y1 terminal as 200001 and the G2 terminal
as 200002 (Flash Programming only). Hardwired
zones can be wired in any of the configurations indi-
cated below:
NC Loops with no EOL Resistor- This is the sim-
plest method of wiring hardwired zones. One or more
normally closed (NC) contact devices may be wired in
series between the Y1 terminal (Zone 1) and the B ter-
minal and/or the G2 terminal (Zone 2) and the B ter-
minal as required. No End-of-Line (EOL) resistor is
required.
☞
Normally Open (NO) devices can NOT be used
in this configuration.
In this configuration there is no supervision or tamper
detection of zones. An open condition will sound an
alarm; a short circuit condition will not be indicated.
To program the system for this configuration, enter
Advanced Programming (See Chapter 3) and set sec-
tion [013] option [1] to ON.
Single End-of-Line (EOL) Resistors - In this configu-
ration normally closed (NC) devices as well as normally
open (NO) devices can be wired to the system. NC
devices are wired in series with a 5600
Ω
resistor. NO
devices are wired in parallel with a 5600
Ω
resistor.
Multiple devices can be wired in a series/parallel con-
figuration on a single zone as indicated below. The
number of devices that can be wired on a single zone
is limited by the wire run distance which must not
exceed 1000 ft. (305 m.).
