Inovonics FA536 - Manual (Page 2)

Operation
Power supply: A 14VAC transformer is provided with the FA536.
Backup battery: An optional 1.2Ah battery (BAT603) can be mounted inside the the outdoor housing.
Low voltage detection: The locator will report low voltage if the supply voltage (either primary or backup) drops into a
preset range.
• AC power failure will not be reported directly—the system receiver and PC will detect inactivity if locator
power is off for the duration of the supervision window.
Supervision: Locators should be programmed to send check-in signals to the receiver, but can operate unsupervised. The
system integrator will assess application conditions and will establish parameters for proper supervision.
Output: The FA536 will NOT repeat signals from other locators or other repeaters. When an FA536 receives a "firsthand"
alarm signal (i.e., a signal coming directly from a transmitter), the open collector output will switch to a "low" state until
either the reset button on the locator is pressed, or the external reset terminal is shunted to ground. The output can be used
to activate annunciation or signalling equipment. Output reset occurs when the transmitter causing the alarm condition
restores (unless locator is factory-programmed to latch).
External reset: A circuit connecting the reset terminal with the ground terminal via a N/O momentary switch can be used
to reset the locator Output terminal.
Test mode: Pressing the Test button will cause the locator to transmit a current status message until the button is released.
Tracking Jumper: When the Track jumper is in the "NO" position, the locator will append identification data to firsthand
alarm signals ONLY. In the "YES" position, data will also be appended to original supervisory (check-in) transmissions.
This permits rough position tracking of roving transmitters, but decreases the locator’s ability to receive alarm transmis-
sions, especially in installations with hundreds of transmitters. (Locators are "busy" sending in supervisory data for signifi-
cant portions of their duty cycles.)
External tamper / Auxiliary input: This terminal can be used to connect a tamper switch outside the case, or to a N/C
input whose activation will cause the FA536 to send a locating tamper transmission.
Locator Range Potentiometer: The Locator Range Pot is provided on the locator to allow the receiver to be desensed, so
the locator coverage can be limited, providing better resolution of location. The Pot can be set from full sensitivity of -
110dB (maximum receive range) to a minimum sensitivity of -40dB (minimum receive range). Locators should be mounted
in locations indicated by system designer. Sensitivity adjustments are necessary whenever replacing a locator.

• " AC POWER" and " BACKUP POWER" LEDs show
locator power source.
• " DECODING" indicates that the locator is receiving
RF energy.
• " TRANSMITTING" indicates that the locator is
transmitting.
Note: The locator does NOT decode while trans-
mitting.
• " NOT ACTIVE" means that the locator has not
received a transmission in a specified period. It is
" waiting" for incoming traffic.
