06/06/05 CP4825C
Wiring - Use wiring capable of handling the current required. Make sure all connections are tight.
Route wiring to prevent wear, overheating and interference with air bag deployment. Install and
check all wiring before connection to vehicle battery.
Testing - Test all siren functions after installation to assure proper operation. Test vehicle opera-
tion to assure no damage to vehicle.
Keep These Instructions - Keep these instructions in the vehicle or other safe place for future
reference. Advise the vehicle operator of the location.
UNPACKING
Inspect contents for shipping damage. If found alert carrier immediately
. Contents should in-
clude unit with attached microphone, wiring harness, mounting bracket, microphone bracket with 2
screws, 2 mounting bolts and these instructions. Contact supplier immediately if any components
are missing.
MOUNTING
The mounting bracket supplied can be installed above or below the unit. Choose a mounting
location convenient to the operator and away from any air bag deployment areas. Inspect behind
mounting area for clearance. Assure adequate ventilation to prevent overheating. Consider wire
routing and access to connections, as well as microphone bracket placement. Install mounting
bracket to vehicle using 1/4" hardware (not supplied).
If mounting in a rack or console, make sure that mounting bolts do not enter case more than 1/4".
OPTION SWITCHES
Various options can be controlled by turning on
or off any of 8 DIP switches internally mounted
on the right side of the PC board.
Cover Removal - The cover is held in place by
a snap-fastener on the back of the unit. While
holding the case on the sides press hard with
your fingers on the back of the unit. The chas-
sis will slide out the front.
Two-Tone - Two-Tone can replace Phaser by
turning on the switch labeled "T-T".
Phaser Disable - The Phaser function can be
completely disabled by turning on the switch labeled "P_I".
Horn Disable - The Horn function can be disabled by turning on the switch labeled “H_I”.
Horn Ring Cycler 2 (HRC2) - This option allows selection of Wail, Yelp, and Phaser by repeat-
edly tapping the Siren button, horn ring or other switch connected to the AUX input. Tapping the
horn ring twice quickly stops tones. Holding the horn ring produces Horn. Turn on switch “HRC”.
See OPERATION section for further details.
Short Manual - The Manual function can be set to immediately cut off when the Siren button is
released. This is selected by turning on the switch labeled “SM”.
NOTE: Earlier models with S/N lower than 04190000 have a 5 position DIP switch and only offer
the traditional auxiliary input.
Traditional Auxiliary Input - The auxiliary input is activated with positive (+VDC) AND negative
(-VDC). A normally open horn ring circuit or switch is required for proper operation. If a normally
open circuit is not used the auxiliary input will constantly be activated. If this is the case, a diode
must be placed in series with auxiliary input to block the normally off state.
Set switch “AUX_1” on and “AUX_2” off for this type of auxiliary input.
Polarity Selectable Auxiliary Input - The auxiliary input may be activated with positive (+VDC)
OR negative (-VDC). Set switch “AUX_1” off and “AUX_2” on for this type of auxiliary input.
Auxiliary Input Polarity - Switch "AUX_P" set on for positive (+VDC) activation or set off for
negative (-VDC) activation. Also “AUX_1” off and “AUX_2” on.
