AC Failure, Low Battery, and Automatic Low Voltage Shutdown
During an AC power failure the battery automatically takes over and AC Fail trouble annunciates at the keypad. The
communicator can be programmed to report AC Fail to the Central Station after a time delay (see Menu 12, System Option 01).
If the battery voltage falls below 11.2 VDC a Low Battery Trouble condition will occur. The communicator can be programmed
to report Low Battery to the Central Station. The battery will continue to run the control until its voltage reaches 10.5 VDC, at
which time the control will disconnect and shut down to prevent a false alarm and damage to the battery. The AC Fail trouble
display will clear if the AC restores. However, the Low Battery Trouble requires a manual or automatic battery load test before
it will clear. An automatic battery load test is performed every 24 hours. See Section 2.2 for powering up the control.
Telephone Line Connection (R1,T1,T,R)
The telephone interface is connected by the use of an approved RJ-31X interconnect jack. This device allows the subscriber
to disconnect the control/communicator from the public switched telephone network in the event of a malfunction. The control
is equipped with line seizure so that the premises telephone service is interrupted during communication to the central
station. Connection to the approved jack is done with a RJSET cord which connects the control terminals to the RJ31X jack.
HELPFUL HINT: The telephone cord can be supervised back to the RJ31X block or Telco demarcation block by installation of
a EOL resistor across the Orange and Blue wires (terminals 2 and 7 on the RJ31X jack). Back inside the control, connect the
Orange and Blue leads from the RJ cord to any 24hr Burglar zone input.
Outputs
There are 12 outputs on the main board. In programming these are numbered Out2, Out3, and Out 7 thru 16. The total
outputs may be expanded utilizing output expander boards connected to the RS-485 4-wire Keypad data bus. The Alarm
Output (Out 2) trips when any alarm is activated. All others must be enabled through the RP Rules Programming and can be
triggered by multiple conditions “events”. Do not exceed the current limits on voltage only outputs.
Output 2 is a traditional Alarm output. It is factory set to produce alarm siren sounds into standard 8 Ohm speakers (never go
below a total connected load of 4 Ohms). It can be alternately programmed to produce voltage only (12VDC) for driving self-
contained sirens or siren driver boards
Output 3 is a Single Pole Double Throw Relay with form “C” contacts (Com, N/O, and N/C).
Outputs 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16 are low current, positive (+) voltage only, for driving LEDs, relays, etc.
Outputs 4,
5, and 6 ARE NOT available from the main board.
They can only be accessed with a data bus Output expander set to
address 1. This expander will replicate all the main board outputs, including outputs 4, 5, and 6.
Earth Grounding
Tests and studies have determined that the best results against lightning and transients are obtained by isolating the control
from ground. Do NOT connect any of the terminals, especially the Neg. terminals to earth ground. However, ancilliary devices
such as the ELK-950 Surge Protector on the incoming Telephone circuit are still recommended.
Keypad & Expanders on the RS-485 Data Bus (+12VKP, Data A, Data B, Neg)
Keypads and data bus expander devices connect to the four terminals VKP, Data A, Data B, and Neg. The keypad
plug-in wire harness color code is: Red +VKP, Green Data A, White Data B, and Black (-) Neg. The +12VKP power terminal is
protected by an auto reset PTC device. In the event of a short circuit or malfunction, power will be removed from all devices
until the problem is resolved.
