Hills Reliance 12 Terminal Descriptions
Terminal
Description
EARTH
Earth / Ground.
To comply with ACA S009 & AS/NZS3000:2000. Connect to the 16.5V AC plug pack earth wire.
AC
AC input. Connect a 16.5V, 25 VA, 40 VA or 50 VA approved transformer.
BELL + &
BELL -
Built in siren driver, if used as a siren output (default), the speaker rating should be
15 Watt at 8 or 16 Ohm, or 30/40 Watt at 4, 8, or 16 Ohm, 250mA maximum load.
If voltage output is selected in Feature 22 - Segment 2 - Option 1, this output becomes voltage
output, 12 VDC, 1 Amp maximum load.
Note:
A 3.3K
Ω
resistor may be required across the bell terminals when a 12 VDC siren is used.
If no resistor is used, you may experience voltage leakage into the siren that will cause these devices
to output a small signal.
KP DATA
Connect the to the KP data terminal on the code pads and the expanders (usually blue or green
wire). Maximum total wire run is 800 metres using 14/020 cable. These numbers are for one code
pad at the end of the wire. When connecting more than one code pad to the system bus wire, a
higher gauge wire will be required, or there will be a reduction in maximum wire distance. Maximum
16 devices.
KP COM
Connect to the Common terminal on the code pads and the expanders (usually the black wire).
KP POS
Connect to the Positive terminal on the code pads and the expanders (usually the red wire).
The KP POS and AUX PWR + terminals are limited to 1 Amp total current when added together.
COM
Connect negative wire of powered devices such as motion detectors and smoke detectors.
AUX PWR+
Connect positive wire of all powered devices except smoke detectors and code pads.
This terminal and KP POS are limited to 1 Amp total current when added together.
ZONE 6
Connect to one side of zone 6 loop. Connect the other side to a COM terminal. Open or short causes
alarm.
COM
Common (-) terminal for zones 5 & 6. (See the wiring diagram for examples)
ZONE 5 -
ZONE 1
Connect to one side of zone loop. Connect the other side to a COM terminal. Open or short causes
alarm. Only zone 7 can be a two-wire smoke zone. (See the wiring diagram for examples)
AUX
OUT 4
(or Zone 7
/Smoke +)
Aux 4 defaults to 12VDC smoke power for a four-wire smoke detector.
Alternatively this output can be programmed in Feature 22 as Zone 7 two-wire smoke detector. Use a
680
Ω
E.O.L. resistor with the two-wire smoke detector. Current is limited to 250mA when output is
negative and 250 microamps maximum when output is positive.
Note:
The 2-wire smoke loop cannot be enabled if Zone Doubling is used.
AUX
OUT 1-3
Connect negative lead of low current device (e.g. relay, LED [install 1K resistor in series with LED],
etc). Connect positive lead of device to AUX PWR +. Current is limited to 250mA when output is
negative and 250 microamps maximum when output is positive.
Battery
Leads
Connect black (-) and red (+) leads to a 12VDC sealed lead acid rechargeable battery.
Do not connect to a dry cell battery.
Warning:
Total
