PEGAsys™ LV
7-6
The alarm sensitivity ranges, by device type, are:
Device Open Area High Velocity
Ionization 0.5–1.5%/FT 0.5–1.0 %/FT
Photoelectric 0.5–3.5 %/FT 0.5–2.0 %/FT
Device 50 ft. Spacing 70 ft. Spacing
Thermal 135°–155° F 135°–145° F
6. This prompt asks the user for the alarm level for the
detector(s) to be set. Key in the desired alarm level
and press the return key. After pressing return the dis-
play will read:
LEVELS SET ON XX DETECTORS
7. This message verifies that the desired sensitivity ad-
justments were done on XX amount of detectors. The
sensitivity of all specified detectors (depending on
which type was previously selected) will be set as in
the previous procedure.
7-11 ADDRESSABLE CONTACT INPUT
DEVICE INSTALLATION
The Addressable Contact Input Devices are designed to
be installed in a North American 2½-in. (64 mm) deep one-
gang box, or a standard 4 in. square box 1½-in. (38 mm)
deep with a one-gang blank cover. The AO terminal block
will accept #14, #16 and #18 AWG wire (1.5, 1.0 and 0.75
mm
2
respectively) with size #18 being a minimum require-
ment. Refer to the wiring the diagram in Appendix I for
specific connection information. Also refer to Paragraphs
2-8.4 and 2-8.5 for setting addresses and other param-
eters. The installation must comply with national and local
electrical codes.
7-12 ADDRESSABLE RELAY OUTPUT DEVICE
INSTALLATION
The Addressable Contact Output Devices are designed to
be installed in a North American 2½ in. (64 mm) deep one-
gang box, or a standard 4 in. square box 1½ (38 mm)
deep with a one-gang blank cover. The AO terminal block
will accept #14, #16 and #18 AWG wire (1.5, 1.0 and 0.75
mm
2
respectively) with size #18 being a minimum require-
ment. See Appendix I for specific connection information.
Also, refer to Paragraphs 2-8.4 and 2-8.5 for setting ad-
dresses and other parameters. The installation must com-
ply with national and local electrical codes.
Note: All Non Power Limited wiring must be routed away
from Power Limited wiring by a minimum of ¼-
inch, per NFPA and UL requirements. For Power
Limited Circuits use Type FPL, FPLP or FPLR
cable per NEC Article 760.
7-13 INSTALLATION CHECKOUT
Before powering up the PEGAsys LV for the first time, en-
sure that the following has been completed:
• Central Control Module (CCM), RX/TX Module and
System Power Supply are secured to the back of the
enclosure.
• CCM is connected to the RX/TX Module, Display As-
sembly, System Power Supply and Remote RS-485
peripheral(s) if any.
• CCM configuration jumpers configured correctly to in-
sure proper operation of the programmable (signal/
release) output (MP1).
• RX/TX Module is connected to the CCM (RJ-12) and
system power supply (24 Vdc).
• Perform the Power-Up procedure in Chapter 4, Para-
graph 4-6.
• Refer to Chapter 2 for system operations and program-
ming.
7-14 CONNECTION OF PERIPHERALS
The following paragraphs will describe how to connect a
terminal or personal computer and a printer.
7-14.1 Connecting a Terminal or Personal
Computer
A UL Listed EDP terminal or computer can be connected
to the system’s RS-232 port. A 6-wire RJ-12 type modular
phone jack (PC port), located on the CCM, provides easy
connection.
The terminal or computer connection cable must have a
RJ-12 type modular phone plug that connects to the CCM
(use P/N 74-100016-003, for a DB9 connector for laptops,
or P/N 74-100016-001 for a DB25 connector for personal
computers). The connector at the terminal end must be of
the type required by the terminal device. Route the con-
nection cable to the RS-232 modular plug labelled PC port
jack until it snaps into place. The terminal or computer
must be located in the same room as the Central Control
Panel.
The parameters for and connections to the RS-232 PC
port are as follows:
Parameters:
• 9600 Baud
• 8 Data Bits
• 1 Stop Bit
• No Parity
Note: These parameters are fixed and not adjustable.
Pin and Function:
•1 TX
• 2 Signal Ground
