500 Series Option Definitions
- Automatic Reset - When the circuitry detects an alarm condition, the
alarm has to be acknowledged by the operator in order to silence the alarm. Once the alarm
condition has been corrected, the circuit automatically rearms itself.
- Manual Reset - Again, when an alarm condition is detected, the alarm has
to be acknowledged by the operator in order to silence the alarm. But, once the alarm
condition has been corrected, the circuit is not rearmed until the operator resets it.
- Latching (memory) Mode - this mode requires the acknowledgment of
temporary as well as a continuous alarm condition. Each occurrence of alarm has to be
acknowledged by the operator, even if the alarm condition has corrected itself.
- Non-latching Mode - In this mode of
operation, the occurrence of temporary, short term, transient alarm conditions need not be
acknowledged by the operator.
- Normally Open Circuit with "Circuit Fail" Detection - The
module can be set up to work for a normally open sensor with "Circuit Fail"
detection. Any break in the wiring of the circuit will be detected with this feature. The
"Circuit Fail" option can be set to be supervised automatically or manually.
- Normally Closed - With this feature the module is set for a normally
- Module Failure Detection (MF) - If any components on a module are removed
or installed incorrectly, this feature detects it. This can be ordered one of two ways. A
normally "off" red LED comes "ON", or a normally "on" green
LED goes "OFF".
- Individual Circuit Test (ICT) - This option allows the testing of each
individual module with an artificial alarm condition. To do so, place a small pointer into
the ICT hole on the face plate of the module and push down on the button. This option is
excellent for troubleshooting faulty wiring.
- Lighted Display - With this option the alarm display is lighted. This
allows greater visibility and easier identification of an alarm condition.
- Light/System Test - This option allows testing of lights on each alarm
circuit. Also during the activation of Light/System Test Switch actual circuitry will be
tested, "Circuit Fail" circuit in the N.O. Mode and actual circuits in N.C.
- Computer Interface - Allows interface with a computer for data logging or
