General description
The EVA-PYH is an attractively-styled, low profile, analog addressable, combination photoelectric smoke/heat detector
for use with the Nittan Control Panel NFU-7000 series in analog fire alarm systems.
This analog addressable combination smoke/heat detector has a specific detector address to provide exact detector
locations throughout the installation. This allows for constant monitoring of the detector sensitivity and reports the
detector's condition to the fire alarm control panel.

Summary of Contents for Nittan EVA-PYH

  • Page 1: Section 1 - Introduction

    Section 1 – INTRODUCTION General description The EVA-PYH is an attractively-styled, low profile, analog addressable, combination photoelectric smoke/heat detector for use with the Nittan Control Panel NFU-7000 series in analog fire alarm systems. This analog addressable combination smoke/heat detector has a specific detector address to provide exact detector locations throughout the installation.

  • Page 2: Section 2 - General Operation

    The EVA-PYH heat detector portion initiates an alarm in response to both 8.3 °C (15 °F) rate-of-rise temperature or a 57 °C (135 °F) fixed temperature alarm point. Heat detector portion incorporates a highly linear thermistor circuit, with the thermistor mounted externally.

  • Page 4: Section 5 - Detector Models

    Section 6 – BASE MODELS There are 5 mounting bases that are available for use with the EVA-PYH. In order to operate correctly, it is important to use the appropriate mounting base as indicated in the table below. Refer to the specific mounting base instruction manuals for details.

  • Page 5: Section 8 - Installation

    The installation must meet the requirements of the Authority Having Jurisdiction (AHJ). The combination detectors offer maximum performance when installed in compliance with the National Fire Protection Association (NFPA); see NFPA 72. Note: NITTAN COMPANY, LIMITED is not responsible for the product which is improperly installed, maintained and tested. 8.1.1 Location requirement When installing the detector please consider the following items.
  • Page 6 8.2.1 Spacing of heat detectors Spot type heat detector spacing is based on detector installation on a flat smooth ceiling at 3 m (10 ft.) high. Spacing of spot type detector is shown in Figure 2. The coverage area of a detector is represented as a square. Actual detector coverage covers a circle whose radius is 0.7 times the listed spacing.
  • Page 7 Listed Spacing 9.1m x 9.1m = 84m (30ft x 30ft = 900ft A : 7.6m x 10.4m = 79m (25ft x 34ft = 850ft B : 6.1m x 11.3m = 69m (20ft x 37ft = 740ft C : 4.6m x 11.9m = 54m (15ft x 39ft = 585ft D : 3.1m x 12.5m = 38m (10ft x 41ft = 410ft...
  • Page 8 The following figure shows the required heat detector spacing for a 60.9 m (200 ft.) by 60.9 m (200 ft.) room with a 3m (10 ft.) ceiling. Figure 6 shows 16 heat detectors with the required spacing of S = 15.3 m (50 ft.). 60.9 m (200 ft.) 7.6 m (25 ft.)
  • Page 9 8.2.2 Ceiling construction and heat detectors When installing heat detectors on other than flat and smooth ceilings or at ceiling height greater than 3 m (10 ft.), spacing must be adjusted. The table below shows the reduction in listed spacing to be applied when detectors are mounted on ceilings higher than 3 m (10 ft.).
  • Page 10 Detectors on Solid joists bottom of joists Figure 8: Heat detector spacing — solid joist construction (plan view) 8.2.4 Exposed beams Exposed beams may impede the heat flow to the detectors. Beams are defined as members extending 10 cm (4 in.) or more down from the ceiling and spaced more than 91 cm (36 in.) apart.

Figure 10: Heat detector spacing — beam construction (plan view) Notes: •Detectors can be installed on the bottom of beams when the beams are less than 30 cm (12 in.) deep and beam spacing is less than 2.4 m (8 ft.).
  • Page 12 8.2.5 Sloping ceiling (peaked and shed) In the rooms with peaked ceilings, the first row of detectors must be located within 1 m (3 ft.)(measured horizontally) of the ceiling peak, but not closer than 10 cm (4 in.) vertically to the peak. Additional detectors, if required, must be located based on the horizontal projection of the ceiling and the type of ceiling construction.
  • Page 13 Smoke detector applications Smoke detectors are designed to sense the presence of smoke particles. In order to sense the particles, smoke detectors must be placed where smoke can reach them. When determining the location of smoke detectors, potential fire locations should first be evaluated, and paths of smoke flows should be determined. It is preferable to conduct actual field tests wherever it is practical to do so.
  • Page 14 8.3.3 Stratification Stratification of air in a room can hinder smoke from reaching ceiling-mounted smoke detectors. In order to improve detection response in situations where stratification exists, it might be necessary to install additional smoke detectors on sidewalls or at locations below the ceiling, as shown in Figure 13. Figure 13: Smoke detector layout accounting for stratification 8.3.4 Partitions...
  • Page 15 8.3.5 Exposed solid joists Exposed solid joists may impede the flow of smoke to detectors. A joist is defined as greater than 10 cm (4 in.) in depth and spaced less than 91 cm (3 ft.) apart. The detectors must be mounted on the bottom of the joists. Figure 14: Smoke detector spacing —...
  • Page 16 8.3.6 Exposed beams Beams are defined as any members extending 10 cm (4 in.) or more down from the ceiling and spaced more than 91 cm (3 ft.) apart. The spacing of smoke detectors must be reduced in the direction perpendicular to the beam. Smoke detectors shall be located on the ceiling in each beam pocket if the ratio of beam depth (D) to ceiling height (H), D/H, is greater than 0.1, and the ratio of beam spacing (W) to ceiling height (H), W/H, is greater than 0.4.
  • Page 17 Procedure for installing Note: All wiring must be installed in compliance with the National Electrical Code, applicable local codes and the Authority Having Jurisdiction. Proper wire gauges should be used. The installation wires should be color coded to limit wiring mistakes and ease system troubleshooting.

Refer to the manual of control panel NFU-7000 series to determine correct maximum loop load and maximum loop resistance for devices connected to each loop.

  • Page 19: Section 9 - Testing

    Tamper resistance feature The EVA-UB series, EVA-S6 Base, and EVA-STB series of smoke/heat detector mounting bases have a tamper- resist feature that works in conjunction with the detectors. W hen this feature is enabled, the detectors cannot be removed from the base without the use of a small hexagonal wrench. To avoid unauthorized removal of the detector, turn the locking screw in the mounting base counterclockwise until the screw extends out about 4 mm (3/16 in.) from the rim of the base, as shown in Figure 20.
  • Page 20 Direct Heat Method (Heat Calibur HO-HC11 Heat Detector Tester) Please refer to the instruction manual of HeatCalibur HO-HC11 for details. Turn Master Power switch on and press the Power button on the panel of the Tester. The LCD Display and LED should light.
  • Page 21 Check that the detector gives an alarm condition within 15 seconds. Check the red LED indicator is on and the green LED is flashing on the EVA-PYH combination detector. If the red LED fails to light, check the power to the detector and the wiring in the detector base.

  • Page 22: Section 10 - Maintenance

    Ensure that no debris remains on or around the thermistor or photo chamber once cleaning is complete. If the unit needs further cleaning, or is damaged or corroded, please return the complete detector to NITTAN COMPANY, LIMITED for warranty service.
