10 EXTERNAL ALARM SYSTEM CONNECTIONS
The alarm interface between the HU and an external alarm system is supported by a six-terminal
plug (with screw-type terminals) that connects to a receptacle mounted on the HU front panel.
The terminal plug provides connections to normally open (NO) and normally closed (NC) dry
type alarm contacts for both major and minor alarms. A category 3 or 5 cable is typically used to
connect the HU to the external alarm system. Use the following procedure to install the alarm
wiring and connect it to the HU:
1. Obtain the required length of category 3 or 5 cable.
2. Route the cable between the HU and the external alarm system (if not already routed) and
then cut to the required length. Allow sufficient slack for dressing and organizing the cable
at the HU.
3. Strip back the outer cable sheath and insulation to expose the wires at both ends of the
cable and strip back 0.2 inches (5 mm) of insulation from each wire.
4. Connect the Major alarm wire pair to the MAJOR COM/NC or MAJOR COM/NO
terminals (whichever is required by the external alarm system) on the HU alarm terminal
connector (supplied with HU) as shown in Figure 3-14.

ADCP-75-150 • Preliminary Issue A • March 2003 • Section 4: Operation
1.2
Readiness Check
Before starting the turn-up process, inspect the complete Digivance system to verify that all
components of the system are ready to be powered-up. This will ensure that no units of the
system will be damaged during turn-up and that all existing systems will continue to function
properly.
1.2.1
Host Unit Installation Checks
Complete the following checks at the HU prior to starting the turn-up process:
1. Verify that the ON/OFF switch on the HU is in the OFF position (press O).
2. At the fuse panel, install a 3 Amp GMT fuse in the circuit that supplies DC power to the HU.
3. Using a DC voltmeter, verify that the DC voltage level at the HU power terminals is
between ± 24 or ± 48 Vdc (can be either polarity).
4. Verify that all electrical and optical connections have been completed and that all optical
fibers, coaxial cables, and wires are properly routed and secured.
1.2.2
Remote Unit Installation Checks
Complete the following checks at the RU prior to starting the turn-up process:
1. Verify that the ON/OFF switch on the STM is in the OFF position (press O).
2. Verify that the MUTE/NORM/RESET switch on the LPA in the MUTE position.
3. At the AC breaker box, close the circuit breaker for the circuit that supplies AC power to
the RU.
4. Using an AC voltmeter, verify that the AC voltage level at the AC outlet is between 110
and 120 Vac (for 120 Vac powered systems) or between 220 and 240 Vac (for 240 Vac
powered systems).
5. Verify that all electrical and optical connections have been completed and that all optical
fibers, coaxial cables, and wires are properly routed and secured.
TURN-UP SYSTEM AND VERIFY OPERATION

ADCP-75-150 • Preliminary Issue A • March 2003 • Section 4: Operation
2.1
Turn-Up Procedure
Use the following procedure to turn-up the system:
1. Temporarily disconnect the external alarm system or notify the alarm system provider that
testing is in progress.
2. If turning-up multiple HU and RU systems that have not been configured for operation before,
temporarily disconnect the CAN cables from the NET IN and NET OUT ports of each HU.
Note: By default, all HU’s and RU’s are programmed with the same site number and
name. This can cause problems for DEMS if multiple HU’s with the same site number and
site name are networked together through the CAN interface. It is therefore advisable to
temporarily disconnect the CAN interface cables from the HU until a unique site number
and name can be entered for each HU and its corresponding RU.
3. Determine if the forward path composite input signal level at the Host Unit FORWARD RF IN
port is appropriate for the required RF output signal level and adjust by installing an external
attenuator if necessary. Refer to Section 2.3 for the calculation and adjustment procedure.
4. Connect the DEMS computer (if not already connected) to the SERVICE connector on the
HU or STM front panel. If necessary, a separate laptop computer loaded with the DEMS
software can be temporarily connected and used to initially configure the system.
5. Place the ON/OFF switch on the HU in the ON position (press I).
6. Make sure the switch on the LPA is in the MUTE position and then place the ON/OFF
switch on the STM in the ON position (press I).
7. Wait 6 to 8 seconds for the HU and the RU modules to initialize and then observe the LED
indicators on the HU, STM and LPA. Refer to Section 5 for the troubleshooting
procedures if the indicators do not respond as specified.
