* OMNIVIEWTM 360 ° LED Indicator for polling and fire alarm indication
Section 2 –GENERAL OPERATION
The VDOT-H2 heat detector 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.
The VDOT-H2-H initiates an alarm in response to 83 °C (181 °F). Heat detector incorporates a highly linear
thermistor circuit, with the thermistor mounted externally. The specially designed cover protects the thermistor while
allowing maximum air flow. The thermistor circuit produces a voltage proportional to temperature which is scaled, and
transmitted as a digitally encoded value to the control panel.

Section 8 - INSTALLATION
8.1 Before installing
These heat detectors must be installed in compliance with the manuals of the Control Panel series.
The installation must meet the requirements of the Authority Having Jurisdiction (AHJ).
The detectors offer maximum performance when installed in compliance with the National Fire Protection Association
(NFPA); see NFPA 72.
Note: ZETA ALARMS 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. Otherwise the detector might not provide optimum
performance.
- Indoor use only.
Place the detector away from a ventilation fan or the air outlet of air conditioner, at least 1.5 m (5 ft.).
- On the ceiling, place the detector at least 10 cm (4 in.) from the wall.
The detector should not be installed in places such as:
- Place with plenty of air flow (close to a ventilation fan, air conditioner, or place with drafts)
- Place close to heating appliance
8.2 Heat Detector Applications
! WARNING
There detectors are intended for use with photoelectric smoke detectors. A heat
detector by itself does not provide life safety protection.
Heat detectors sense change in air temperature and initiate an alarm condition based on a fixed-temperature point,
rate of temperature rise, or amount of temperature rise above ambient condition. Spot type heat detectors should be
selected so that the rating is at least 11 °C (20 °F) above maximum expected ceiling temperature. Ceiling height,
construction, and ventilation play significant roles in detector performance and must be considered when determining
detector placement. The operating temperature range is 0 °C to 37.8 °C (32 °F to 100 °F)for VDOT-H2 and 0 °C to
65.6 °C (32 °F to 150 °F) for VDOT-H2-H.

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. Since all of the area within the
detector’s circle of coverage is suitable for detecting a fire, the shape and dimensions of the detector coverage
“square” in Figure 3 may be modified. Coverage area should remain within the overall detector circle of coverage as
shown in Figure 4.

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.). This reduced spacing allows the detectors to have the equivalent
response of detectors located on a 3 m (10 ft.) ceiling.

8.2.3 Exposed solid joists
Exposed solid ceiling joists may impede the heat flow to the detectors. A joist is defined as a solid member projecting
down from the ceiling surface for a distance of more than 10 cm (4 in.) and spaced at intervals of 91 cm (36 in.) or
less, center to center. The spacing of heat detectors must be reduced by 50% in the direction perpendicular to the
joist. The detectors shall be mounted on the bottom of the joists.

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. The spacing of heat detectors must
be reduced by 33% in the direction perpendicular to the beam. Detectors can be mounted on the bottom of the
beams which are less than 30.4 cm (12 in.) in depth and less than 2.4 m (8 ft.) on center. If beams are greater than
46 cm (18 in.) in depth and are spaced more than 2.4m (8 ft.) on center, then each bay formed by the beams must
have at least one detector mounted on the ceiling. 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, heat detectors
should be located in each beam. If either the ratio of beam depth (D) to ceiling height (H), D/H, is less than 0.1 or
the ratio of beam spacing (W) to ceiling height (H), W/H, is less than 0.4, heat detectors should be located on the
bottom of the beams.
Calculation:
D/H > 0.1 AND W/H > 0.4 : Mount the detector on the ceiling
D/H < 0.1 OR W/H < 0.4 : Mount the detector on the bottom of the beam

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. In the rooms with shed ceilings having a slope greater than 1 m in 8 m (1 ft. in 8 ft.), the first
row of detectors must be located within 1 m (3 ft.) of the high end of the ceiling. Additional detectors, if
required, must be located based on the horizontal projection of the ceiling and the type of ceiling
construction. For a ceiling slope of less than 30 degrees, all detectors must be spaced using the height at the
peak. For a ceiling slope of 30 degrees or greater, all detectors must be spaced using the average slope
height or the height of the peak.

8.3 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. Improper connections will prevent a system from responding properly in the event of a fire.
Remove power from the communication line before installing heat detectors.
1. Pass the field wiring through the rear center cable opening in the mounting base. Install the base to the
electrical box with screws via the base mounting holes. Connect the field wiring to the base terminals, as
detailed in Figure 13. Do not use looped wire under terminals (See Figure 14).
2. Using the VDOT-AD2 Address Programmer, set the desired address for each heat detector. See Annex A for
the handling.
3. Install the heat detector into the mounting base, making sure the wiring does not obstruct mounting of the
detector head. Push the heat detector into the mounting base while turning it clockwise until the heat detector
locks into place. Use a small hexagonal wrench to set the tamper resist feature (if required), see Figure 15.
4. After the heat detector has been installed, snap on the supplied plastic dust cover onto the detector to keep out dust
duringconstruction.
5. Apply power to the control panel to configure the detectors to the fire alarm control panel.
6. Test the heat detector(s) as described in the TESTING section of this manual.
After commissioning has been completed remove and discard the dust cover.
! CAUTION
Smoke and heat detectors are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose.

8.4 Tamper resistance feature
The VDOT-UB series, VDOT-S6 Base, and VDOT-STB series of smoke/heat detector mounting bases have a
tamper- resist feature that works in conjunction with the heat detectors. When this feature is enabled, the heat
detectors cannot be removed from the base without the use of a small hexagonal wrench. To avoid unauthorized
removal of the heat detector, turn the locking screw in the mounting base counterclockwiseuntil the screw extends
out about 4 mm (3/16 in.) from the rim of the base, as shown in the Figure 15.
Figure 15：Position of the locking screw to lock the detector
Note: If the detector is installed on a high ceiling where a tool (ladder, etc.) is needed, it is not recommended to
use the locking screw.
Section 9 –TESTING
Notes: •Before testing, notify the proper authorities that the system is undergoing maintenance, and will
temporarily be out of service.
•Disable the system to prevent unwanted alarms.
•All sensors must be tested after installation and periodically thereafter.
•Testing methods must satisfy the Authority Having Jurisdiction (AHJ).
•When carrying out site testing of the detector, the control panel must be set to “One Man Walk Test”
mode prior to the test.
Sensors offer maximum performance when tested and maintained in compliance with NFPA 72. The sensor may
be tested in the following ways:
A. Direct Heat Method (Hair dryer of 1000 –1500 watts )
1. From the side of the detector, direct the heat toward the sensor. Hold the heat source about 15 cm (6 in.)
away to prevent damage to the cover during testing.
2. The red LEDs on the detector should light when the temperature at the heat detector reaches the alarm
set point. If the red LED indicator fails to light, check the power to the detector and the wiring in the
detector base.
3. After the detector has given the alarm condition, the detector automatically is reset by the control panel.
The detector can also be reset at the control panel manually. Detectors that fail these tests should be
cleaned as described under MAINTENANCE Section and retested. If the detectors still fail these tests
they should be returned for repair.
