PEGAsys
Intelligent Suppression Control/Fire Alarm System
7-10
7-12 EXTERNAL POWER FAILURE INDICATOR
CONNECTION
The PEGAsys System provides a 2 A @ 30 VDC SPDT relay on
the power supply control unit that de-energizes (normally pow-
ered) in the event of a power supply monitor trouble - troubles
include:
• AC Power Failure
• 24 VDC Power Supply Failure
• Battery Failure
• Ground Fault
• Communications Failure
The power supply trouble relay is normally powered so that in
the event of power failure the relay will transfer to the normally
closed position. The contact can be used to signal an external
power supply trouble indicator.
The connection cable to an external power supply trouble indi-
cating device is to be run through a conduit from the indicating
device to the Central Control Panel. The conduit must be at-
tached to any convenient Central Control Panel enclosure knock-
out. Connect cable to TB1 on the Central Control Panel’s power
supply PCB as shown in Figure 3-6.
7-13 DETECTOR INSTALLATION
Refer to the SmartOne Smoke and Heat Detector Installation
Sheet (74-212) for installation instructions. Also, refer to Chap-
ter 2, Paragraph 2-8.6 for setting addresses and registering
RCUs.
7-14 SETTING AND ADJUSTING SMOKE & HEAT
DETECTOR SENSITIVITIES
Setting the sensitivity of SmartOne ionization and photoelectric
smoke detectors and heat detectors is accomplished by setting
the threshold alarm and pre-alarm smoke density levels. The
SmartOne smoke detectors (Ionization and Photoelectric) were
previously programmed for a device application during the reg-
istration process.
The smoke detectors have specific sensitivities for particular
applications. There are 3 applications which represent the ma-
jority of detector use: Open Area, Open Area (High AirFlow)
and Duct.
The sensitivity adjustment is accomplished in one of two ways:
1. Smoke & Heat Detector Configuration. During the
process of configuring the system using the PCS program, the
operator selects the application of the detector and adjusts the
settings of the alarm and pre-alarm values within the range for
the application chosen, or accept the default values for the ap-
plication.
2. Level Setting Operation. This procedure is selected
from the menus. This method is generally used for systems
which have been installed and operational for a period of time.
It should only be used if there is a need to change the sensitiv-
ity of the device.
7-14.1 Setting and Adjusting Smoke and Heat
Detector Sensitivity Procedure
The step-by-step procedure to perform the setting sensitivity
test follows:
a. Access the PEGAsys system menu’s by:
(1) Press 0 (zero) key. Verify that the display reads:
PLEASE ENTER PASSWORD
(2) Type in the Level 2 password.
(3) Press the return (
↵
) key. Verify that the display
reads:
1:ISOLATE 2:LIST
3:SET 4:TEST
b. Select the Detector Sensitivity by typing in 3-3-2. Verify that
the display reads:
1:IONIZATION 2:PHOTOELECTRIC
3:THERMAL (<) to return
c. Select the desired detector style which is to have its sensi-
tivity adjusted. After type selection, the system display:
SET DETECTOR SENSITIVITY
DETECTORS FROM _ _ _ _ TO _ _ _ _
NOTE: The user would enter the address range of the
detectors to be adjusted. The range can be from 1 to
255. The system will adjust the sensitivity of all the
specified type of detectors which were previously
chosen (Ion, Photo or Heat) within the range.
d. Press the return pushbutton and the display will read:
SET DETECTOR SENSITIVITY
PREALARM _._ (0.2 -3.0 / FT)
TOLERANCE RANGES
Device Open Area High Velocity
Ionization 0.5 - 1.5%/FT 0.5 -1.0 %/FT
Photoelectric 0.2 - 3.5 %/FT 0.2 - 2.0 %/FT
Device 50-FT spacing 70-FT Spacing
Thermal 80° - 155° F 80° - 145° F
e. This prompt asks the user for the Pre-alarm level for the
detector(s) to be set. Key in the desired pre alarm level
and press the return key. After pressing return the display
will read:
SET DETECTOR SENSITIVITY
ALARM _._ (0.5 -3.0 / FT)
TOLERANCE RANGE
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
