5.
Terminal strip 3 (
TS3
) can be used to access the Fail Output circuit (see Section V
below).
6.
Install up to three Model H1 loop detectors onto the Model HM1 Motherboard. Plug
the detectors onto the 10-pin male Molex connectors labeled
1
,
2
, and
3
.
7.
Set the
SW1
DIP switches to the appropriate positions. See
DIP Switch Settings -
DIP Switch 1 (
SW1
)
table.
8.
Apply appropriate power to the HM1 Motherboard.
III. DIP Switch Settings - DIP Switch 1 (SW1)
The HM1 Motherboard incorporates a three-position DIP switch module labeled
SW1
. Set
the individual DIP switch (labeled
1
,
2
, or
3
) to the
ON
position when a detector
is not
connected to the corresponding 10-pin male Molex connector. Set the DIP switch (
SW1
)
to the
OFF
position when a detector
is
connected.

V. Fail Outputs - Terminal Strip 3 (TS3)
The Fail Output circuit on terminal strip 3 (
TS3
) can be used to send an indication to an
external device whenever a detector experiences a loop failure (open loop or shorted loop)
or power loss. The following table lists the HM1 Motherboard Fail Outputs when detectors
are installed. Contact Reno A&E at (775) 826-2020 or [email protected] for additional
information on the use of this feature.

VI. Reset
Press the motherboard mounted pushbutton labeled
RESET
to reset all detectors. The
detectors automatically tune and are operational within two (2) seconds after being reset.
Full sensitivity and hold time requires 30 seconds of operation.
