Installation, Operation & Maintenance

Main Board Connections

POWER/ LINE IN.

110-120Vac mains power should be supplied to the [POWER/LINE IN] connector using a 3 core cable and fused at

3A. When mains power supplied to the panel - a red LED will illuminate located on the front cover.

OUTPUT 1 RELAY.

This relay output switches when any external gas detectors reach 'pre-alarm' status and the [0-10V OUTPUT] will

send 5V to ventilation systems.

OUTPUT 2 RELAY.

This relay output switches when any external gas detectors reach 'alarm delay' status and the [0-10V OUTPUT] will

send 10V to ventilation systems.

ALARM RELAY.

This relay output switches when any external gas detectors reach 'alarm delay' status for longer than the selectable

5 - 25 minutes time following the [OUTPUT 2] relay.

DAMPER RELAY.

This relay output can switch together with either OUTPUT 1, OUTPUT 2 or ALARM relays - selectable in the settings

menu.

DETECTOR CHAIN.

24vdc power and Modbus data is wired to Parksafe gas detectors [DETECTOR CHAIN] - [+ / - / D+ / D-].

Up to 16 detectors can be connected, chained in parallel up to approx. 500 yards from the panel depending on chain

configuration, wire type for power and condition. Connect detectors in a parallel (daisy chain) method.

Any other way may cause communication issues or damage to the overall system.

For MODBUS communications, a shielded and twisted pair cable is used. The shielding can be of 2 types: braided

[mesh of thin conducting wires] or foil (consisting of a thin sheet of metal covering the twisted wires).

If you are encountering noise or irregular problems with a Modbus link, the problem is likely related to grounding,

incorrect shielding or wiring mains power next to Modbus wiring.

For more information, refer to your Parksafe detector manual.

SOUNDER/ STROBE.

This relay output (24VDC) is for an external sounder alarms/ strobe lighting to activate on alarm.

24VDC

This is a permanent 24Vdc power output for external auxiliary devices. Max output: 200mA.

0-10V OUTPUT.

This output can drive ventilation systems. Under normal operating conditions, this output can send either 0 or 2V –

selectable in the settings menu. The [0-10V OUTPUT] will send 5V when [OUTPUT 1] relay is activated and 10V

when [OUTPUT 2] relay is activated.
