System 2 Installation / Programming Manual

Zone Inputs

The System 2 can monitor a “normally closed” or “closed circuit” switch or alarm contact mounted on a door

to report a Zone Condition. Each System 2 has one input for each of the two doors. When the door is opened

or closed, an event is generated, which can be used to activate any of the System’s Auxiliary outputs.

Emergency Drop Input

This input can be used to open the normally closed contacts on both main relays. When (+)12VDC is applied

to this input, the main relay’s normally closed contact will open - disconnecting power to the magnetic locks on

both doors and generating an event. This feature is not applicable to door strikes wired to the normally open

contact of the relay.

Reset

The reset button (SW1) is located in the upper right hand corner of the circuit board. This button, when

pressed, will initiate a "soft boot" of the system which will reset the main microprocessor and test the memory.

If memory is corrupted, the System will prompt you to clear memory now or later. The system may continue

to operate with corrupted memory to some degree however, memory will need to be cleared and

reprogrammed. This feature allows the clearing and reprogramming to be preformed at a more convenient

time. If memory is not corrupted, a system reset event will be generated with no other consequences.

LED Indicators

The System contains 19 LEDS on the circuit board which identify various system functions. The ACTIVITY

LED & AC POWER LED are visible through transparent windows in the front panel of the cabinet. A

blinking ACTIVITY LED indicates a normal, functioning system. A steady AC POWER LED indicates that

16.5 volts is present to supply main power to the unit. The other LEDS, except DROP RELAY LED, go “on”

to indicate relays and outputs that are active, RS232 status, RS485 status and the presence of auxiliary voltages

for +5, +6, +12 volts DC. BATT RELAY LED, which is normally “on”, goes out to indicate the external

standby battery is supplying power to the system

Circuit board LED markings are: RELAY 1 (Main Relay 1); RELAY 2, (Main Relay 2); AUX1, (Auxiliary

Relay 1); AUX2, (Auxiliary Relay 2); VO1, (Voltage Output 1); RXD, (RS232 Receive Data); TXD,

(RS232 Transmit Data); CTS, (RS232 Clear To Send), DCD, (RS232 Carrier Detect); RS485 RXD & TXD

(Data Activity); DROP RELAY LED indicates that the emergency Drop Input is active. BATT RELAY

LED, when off, indicates that the external standby battery is operating the system.

Time Keeping

The System contains an active time keeping clock chip that is activated at time of manufacture. This clock is

accurate to +/- 60 seconds per year and is used to time stamp system events and record time-in-service for

warranty purposes. Powered by an on-board lithium battery, this clock chip will keep time for 50 years.
