Installation & Operation Manual

Board Connections Overview

1. 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 is supplied to the panel - a red LED

will illuminate located on the front cover.

2. 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 1-5 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.

3. DETECTOR CHAIN 12-24Vdc power and Modbus communication 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.

4. SOUNDER/ STROBE This relay output (24VDC) is for an external sounder alarms/ strobe lighting to

activate on alarm.

5. 24VDC This is a permanent 24Vdc power output for external auxiliary devices.

Max output: 200mA.

6. 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.
