Tattletale Rate of Rise Sensor User manual

Rate of Rise Sensor
GENERAL INFORMATION
The Rate of Rise Sensor can be placed up to 2000 feet
away from the tattletaleTM base unit depending on structures
and objects in-between the sensor and the tattletale.
A temperature increase of 15°F or more per minute activates
the rate-of-rise feature and transmits an alarm to the tattletale.
Additionally, if the ambient temperature rises above 194°F,
the xed temperature element will activate, the center disk
will fall free from the sensor, and will transmit an alarm to the
tattletale. It can eectively detect change of heat in an area up
to 2,500 ft. It will operate at temperatures from -22°F to 150°F.
The 3V CR123A battery included with the Rate of Rise Sensor
will typically last 2-3 years.
IMPORTANT:
YOUR tattletale™ BASE UNIT DOES NOT NEED
TO BE ARMED TO SEND AN ALARM FROM ANY
FIRE SENSORS, INCLUDING YOUR RATE OF RISE
SENSOR.
PLEASE CALL 1-888-835-5668 OR USE TEST DRIVE
FUNCTION TO PLACE YOUR ACCOUNT ON TEST
BEFORE TESTING OR SERVICING YOUR RATE OF RISE
SENSOR IN ANY WAY. FAILURE TO DO SO CAN CAUSE
DEPLOYMENT OF THE FIRE DEPARTMENT.
General Troubleshooting
1. When there is an issue with your Rate of Rise sensor
(or one of your other sensors), the tattletale base unit
will display a message on its screen which says either
“Sensor Open” or “Other Issues.” If you see either of
these messages displayed, press 3 on the keypad, then
enter your 4-digit PIN to get more information about
what is going on with the sensor.
2. If the Rate of Rise Sensor’s status is “LOST,” verify that
it is within range of the tattletale base unit and that the
sensor has a working battery in the
transmitter. If that doesn’t return it to normal status a
tattletale signal booster might be needed.
3. If the Rate of Rise Sensor’s status is “LOW BATTERY,”
replace the CR123A battery in its transmitter and press
the black RESET button.
If the Rate of Rise Sensor was exposed to
temperatures above 194°F and the sensor is
constantly reporting open, it will need to be
sent to tattletale for repair/replacement.
Instructions for mounting, testing and changing the battery,
are located on the following pages.

Mounting instructions:
Use the mounting tabs on the box (screws not provided)
OR the included Dual Lock adhesive strips to attach the
Rate of Rise Sensor to the ceiling. The best location for
the sensor is at a high point where heat will build. The
recommended mounting height is 10ft. The rst sensor
near a wall should be placed no more than 25ft away
from the wall, additional sensors away from the wall can
be spaced at 50ft (see g.1)
Sensors should be mounted no less than 4” from any
corner and no more than 12” from ceiling (see g. 2)
Mounting is possible above the height of 10ft but spacing
between sensors and walls will decrease with additional
height. (see g. 3) or contact tattletale for specic mount-
ing instructions).
When mounting sensors on ceilings with exposed joist al-
ways mount sensors below, not between joist. (see g.4)

NOTE: Do not mount sensors where they can be
directly exposed to rain or snow.
Do not mount sensors in the direct path of hot or cold air ow.
These conditions can cause alarm events and/or adversely
aect the sensor’s sensitivity.

Be sure to press the
reset button after
changing the battery
Follow these steps to change the battery:
Fig. 1 (transmitter)
1. Call 1-888-835-5668 or use test drive function to put
your account on test to avoid accidental dispatch of
the Fire Department.
2. Take the sensor down from the ceiling.
3. Remove and set aside the six screws securing the back
plate. Remove the back plate.
4. Locate and replace the CR123A 3V battery. Be sure to
orient the battery so that the positive (+) and negative (-)
ends of the battery line up with the markings inside the
battery housing.
6. Press the black RESET button (Fig. 1).
8. Mount the sensor, then call 1-888-835-5668 or use
the test drive function to take your account o of test.
Testing the Rate of Rise Sensor
Because your tattletale base unit does not need to
be armed to send alarm signals from re sensors,
testing your Rate of Rise Sensor can cause the Fire
Department to be deployed.
To avoid this situation, please call 1-888-835-5668
or use the test drive function to put your account
on test, and to be guided through the process of
testing your Rate of Rise Sensor by a technical
services representative.
The Rate of Rise Sensor is subject to reduced
sensitivity over time. Annual testing of the
sensor is recommended.
