Tamper resistance feature
The EVA-UB series of smoke/heat detector mounting bases have a tamper- resist feature that works in conjunction
with the detectors. When 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 11.

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. For the smoke detector testing (Go / No-Go)
1.
To test the optical detector, introduce a certain amount of aerosol into the detector
’
s head, using
Solo 330
Aerosol Dispenser with Solo A3 Smoke Detector Tester (No Climb Products Ltd.). Please follow the
manufacturer’s recommendations on their use.
2.
Check that the detector gives an alarm condition within 15 seconds. Check the red LED indicator lights on the
EVCA-P
smoke detector. If the red LED 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. It
may be necessary to allow a short time to elapse before resetting the detector, to allow any residual aerosol
from the test to disperse.
4.
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.
5.
Before proceeding to the next detector, ensure that the detector previously tested does not re-operate due to
the presence of residual aerosol.
