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.

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.

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 LED 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.
