WIRE CHECK-OUT
After connecting wires to the sounder, and before connecting to the control unit, systematically
measure the resistance between each wire with every other wire.
Resistance should never be less
than 75 ohms
. Resistance less than 75 ohms shows damage to the wire between control unit
and sounder (e.g., a staple through the wire) and will damage the power supply if it is connected to
the control unit.
CT-A1 SOUNDER FEATURES AND INSTALLATION INSTRUCTIONS
THREE TONES
The CT-A1 allows three tones: steady, slow-pulse, fast-pulse. It is suggested the installer sample
the tones for the customer to choose. To hear a sample of the steady tone, push the button marked
“PROG.” To hear a sample of the slow-pulse tone, push the button marked “DOWN.” To hear a
sample of the fast-pulse, push the button marked “UP.” Note: power must first be applied to the
CT-A1 before it will sound.
PROGRAMMING VOLUME
To adjust volume, keep the button marked “PROG” pushed in the entire time you are increasing or
decreasing volume (it will continue to sound as long as it is pushed in, demonstrating adjusted
volume).
With “PROG” pushed in, push the button marked “UP” to increase volume one increment. Keep
“PROG” pushed in, wait one second, and push “UP” again. Repeat until desired volume is reached.
With “PROG” pushed in, push the button marked “DOWN” to decrease volume one increment.
Keep “PROG” pushed in, wait one second, and push “DOWN” again. Repeat until desired volume is
reached. Note: when highest or lowest volume setting is reached, the LED will blink once.
MUTING SOUNDER
To mute sounder, keep “PROG” button pushed in and push the “DOWN” button two times in quick
succession (in less than one second). The LED will begin blinking and continue blinking the duration
of the mute cycle. To restore sound, hold “PROG” button down and push the “DOWN” button two
times in quick succession as before. The LED will stop blinking when sound is restored to its
previous setting.
ADJUST TIMING (OPTIONAL)
The default timing for the CT-A1 is set at the control unit (see “Adjusting Sounder (Annunciator)
Time” on page 10). However, if a longer sounding time is desired for individual CT-A1’s, it can be
lengthened by turning the pot on the sounder’s circuit board counter-clockwise (CCW).
“ON”, “RESET” and “EXIT” ADDITIONAL FEATURES AND “CHIRP”
The CT-A1 has additional features made available by three function-buttons on the plate:
The “ON” button instantly trips the floodlight timer and the floodlights are switched on for the time
period set by the control unit or until the “RESET” button is pushed.
“RESET” instantly cancels the floodlight timer and turns off the lights operated by the CF-2C.
“EXIT” button activates the preset exit delay timer, de-activating the sensor probe. This allows a
vehicle to drive by the probe without tripping the system, Normal standby mode occurs after the exit
delay timer times out (see “Adjusting CT-A1 Exit Delay,” on page 9).
These buttons lack a tactical feel, but when pushed, a small audible “CHIRP” should be heard.
SPECIAL NOTE:
Many installers use the CT-A1 as a means of safety for the woman home alone at night.
By installing the CT-A1 just outside or inside the master bedroom, one need only push the “On” button
from the convenience of the bedroom when suspicions are raised by outside noises. Doing so will turn
on all lights operated by the CF-2C and inform outsiders, if they exist, that they have been detected.
