Terminals Wiring Information
PGM 1
This is a programmable open-collector auxiliary
output (100 mA max.). You may program this output
to pull to ground upon communication failure.
Alternatively, you may program it to pull to ground for
as long as the system is armed (for controlling the
alarm memory function in certain detectors), or for
lighting an remotely located LED to indicate that the
system is armed.
An LED with 1k
Ω
resistor in series may be wired
between
PGM1
and any one of the
12 V+
terminals,
as shown in Fig. 3.6. A relay can also be wired as
shown with PGM2.
PGM 2
This is a programmable open-collector auxiliary
output (100 mA max.). You may program this output
to pull to ground during exit and entry delays, or to
pull to ground whenever the system is ready - all
zones are secured and ready to be armed. In the first
case, a courtesy light control relay or a warning
buzzer may be wired between
PGM2
and any one of
the
12 V+
terminals (Fig. 3.6). In the second case, a
READY LED with a 1k
Ω
resistor in series may be
wired between
PGM2
and any one of the
12 V+
terminals.
PGM 3
This is a programmable open-collector auxiliary
output (100 mA max.). You may program this output
to reset smoke detectors after the first detection of
smoke, or to pull to ground upon any alarm and return
to the open circuit state only by disarming or arming
the alarm system (strobe output). In the first case,
PGM3
must be wired as the "ground return" for the
smoke detectors used in the system, as shown in
Figure 3-6. In the second case, a strobe light control
relay may be wired between
PGM3
and any one of
the
12 V+
terminals.
ALM
This is an open-collector output that pulls to ground
during alarm and returns to the open circuit state
when the alarm times out. It may be used to activate
an auxiliary alarm device.
ALARM
The
N.O., C
and
N. C
. terminals represent the
corresponding output relay contacts. You may wire
the alarm relay contacts to switch on an external
siren by supplying +12 VDC to the siren as shown in
Fig. 3.7.
Note: If the V-BELL jumper is installed across the
two V-BELL pins, +12VDC is applied to the output
relay C contact. The N.C. contact will also be at
+12VDC potential, but will become "floating" when
an alarm occurs. If you wish to use the output
relay as a "floating" dry contact switch, be sure
to remove the V-BELL jumper!
12 VDC
Two pairs of 12 VDC supply terminals. Up to 700 mA
maximum current can be obtained across the [+] and
[–] terminals, but this includes the current. drawn by
the keypads, the zone expander and the various
detectors.
16 VAC
AC power input terminals. The system is powered by
16 VAC output from a 40 VA power transformer,
which changes according to the country of use. The
secondary winding of the transformer (the two free
wires extending from the transformer) must be
connected across these terminals.
