Section 1 – INTRODUCTION
VDOT-STB-RL is a detector base with relay output for use with Zeta Control Panel series, which is designed for
use with an addressable detector. When a detector is in alarm condition, the base receives a control signal from
the detector, which has the relay operate. The rating of contact is DC30V/1A.
Section 2 – TERMINALS
VDOT-STB-RL base is supplied with 2 terminals as standard, along with a relay output terminal block of C form
contact.
The terminals of VDOT-STB-RL base are configured as follows:
-Terminal 1 = SLC positive
-Terminal 6 = SLC negative
-Terminal 3 = No connection
- Relay terminal block with N/O, N/C, and COM
! CAUTION
Do not use the products outside the rated power supply voltage range specified in
the Specifications. It may cause a fire or damage to equipment.
Do not disassemble, repair, or modify the products. It may cause a fire or electric
shock.
! CAUTION
! CAUTION
Make sure to turn the power off before commencing any wiring work. Otherwise
it may cause electric shock or damage to equipment.

Section 6 – CONNECTIONS
Install wiring in accordance with Figure 4 in this document.
All wiring must conform to applicable local codes, ordinances, and regulations.
Figure 4: Connection to Zeta control panel series
Figure 5: Connection to terminals
For system monitoring - for terminals 1 and 6, do not use looped wire under terminals.
Break wire run to provide monitoring of connections.
! CAUTION
Before installing the product check the continuity, polarity and insulation resistance of all wiring. Check that siting
is in accordance with the site system drawings and conforms to all applicable local codes such as NFPA 72.
In normal use, the VDOT-STB-RL base will be installed at ceiling level. Pass the field wiring through the cable
hole in the center and from the rear of the base. Hold and affix the base to the ceiling or electrical box with screws
via the base mounting holes. Connect the field wiring to the base terminals, as detailed in Section 5 and 6,
Connect to optional equipment
Output (Normal standby status)
・ Close between N/C-COM
・ Open between N/O-COM
Correct Wiring
Incorrect Wiring
Use cable AWG12-20 for SLC terminals, and cable AWG14-22 for relay terminals.
Do not connect different gauge cables at one terminal in order to prevent loosening.
! CAUTION
Do not connect cables in reverse polarity. Failure to connect the polarity correctly
could result in damage to the base and/or other equipment.

making sure the wiring does not obstruct fitting of the detector head.
Fit the detector head by inserting it into the base and turning clockwise until the notch in the detector rim aligns
with base locking screws. To avoid unauthorized de-installation, turn the locking screw counterclockwise until the
screw comes to about 4mm(3/16”) from the rim of the base, as shown in Figure 6. The OMNIVIEWTM 360°
indicator permits visibility from any angle.

Note: Smoke and heat detectors are not to be used with detector guards unless the combination has been
evaluated and found suitable for that purpose.
Section 7 – MAINTENANCE
Maintenance
The VDOT-STB-RL is a high quality product engineered for reliability. In order to obtain optimum performance,
periodic maintenance is required, at lease in accordance with NFPA 72 chapter 14 “Inspection, Testing and
Maintenance”.
Routine Inspection:
Ensure the detector head and the base are secure and undamaged.
Operation Test:
The purpose of the Operational Test is to confirm the product’s correct operation.
1) When carrying out site testing of the product, the control panel shall be set to “one-man-walk test mode” prior
to the test.
2) Take any necessary precautions to limit the sounding of the alarm sounders/bells and any fire service
summoning device.

3) Operate the detector in accordance with each detector's instruction manual as mentioned in Section 4. Check
that the LED indicator on the detector illuminates. When the detector goes into an alarm status, confirm that
the output relay of the product is in operation (close between N/O and COM, open between N/C and COM).
Please note that the output relay operates if the detector is in operation even though in
the “one-man-walk test mode”. Take appropriate measures depending on the situation
in the field.
! CAUTION
Note: If the test cannot be carried out by operating the detector, remove the detector and short between terminal
3 and 6 to check the relay switches.
4) After the detector has given the alarm condition, the detector is automatically reset by control panel. It may be
necessary to allow a short time to elapse before resetting the detector.
Confirm that the output relay goes back to the initial status (open between N/O and COM, close between N/C
and COM) after the detector is reset.
Note: For detector testing and cleaning information, refer to each detector's instruction manual as mentioned in
Section 4.
