System Operation
Turning your system on and off
Power is applied and removed with a key switch located on the electronics enclosure. Two keys are supplied with the system.
Remove the key while the system is operating to prevent patrons from turning off the system. If the key is not available and
power must be removed, unplug the power cord or turn off the circuit breaker in the power distribution panel that supplies
power to the system. Your detection system has been designed to be left on continuously.
Turning the system on
1. Ensure that the power cord is connected to a power outlet or other source of power.
2. Turn the key switch to the On position.
3. Allow 15 seconds for the system to warm up.
Turning the system off
Remove power from the system by one of the following methods:
• Turn the key switch to the Off position.
• Disconnect the AC power cord from the power outlet.
• Set the facility circuit breaker for the system to the Off position.
Verifying system operation
Your system should be inspected daily for proper operation. To verify system operation, walk through the system corridor
with a secured library item. This should result in an audible alarm and a flashing alarm light at the top of the lattices. Also,
the green alarm/inhibit light on the electronics enclosure should be flashing yellow at the time of alarm. There is no need
for repetitive walk-through testing. During normal operation, the current patron count is displayed. Each pass through
the system should increment the patron counter by one.
Fuse replacement
The fuses are located on the bottom of the electronics enclosure in the power entry connector.
1. Turn the key switch to Off and disconnect the power cord from the power source.
2. Using a small flat-blade screwdriver, remove the fuse block from the power entry connector.
3. Do not remove the voltage selection block as this has been set at the correct voltage by the installer.
4. Replace the failed fuses with the correct fuse for your operating voltage:
• Up to 100 to 120 VAC, use a 4A fuse.
• Voltages over 220 to 240 VAC, use a 3.15A fuse.
5. Reinstall the fuse block, connect the power cord to the power source, and turn the key switch to On.
