BoilerGuard

The BoilerGuard is a low-cost complete plant room safety system providing a central interface for all common safety systems such as fire alarms, thermal links and gas sensors. With the option to include gas pressure proving, this can also, be used when flame failure devices are not fitted.

Any combination of sensors from the FGS range can be connected by simply wiring in parallel, cutting down on installation costs. The communication interface allows all sensor information to be displayed on the panel, this includes gas type, concentration, status, alarms and calibration data.

The relay outputs allow the unit to be connected to external systems or alarm beacons and the latching facility combined with the additional device interfaces offer the flexibility to cover any application.

Key Features

• Auto-reset following power failure
• Fire alarm test bypass timer
• 24VDC auxiliary power output to power 4-6 Flamefast Gas Sensors dependant on sensor type. External power supply required for additional.
• Additional Interfaces for:
  • Thermal Links, Ventilation Systems, Remote Emergency Stop Buttons and Fire Alarm Systems
• Sensor calibration reminder
• Alarm 1, Alarm 2 and Fault relays
• Selectable relay latching function
• UK MANUFACTURED

Basic Operation

The BoilerGuard has three buttons on the front:

Reset - The BoilerGuard Alarm 1 and 2 relays are activated depending on the sensor conditions. Following an alarm the reset button can be used to reset any relays that are set to latch including the Gas Valve output which will shut down if any sensor reaches Alarm 2..

Mute - If there are any gas alarms, this can be used to silence the panel for 15 minutes. If this is held in for 10 seconds, this will also reset any non-latching alarm relays for 2 minutes.

Test - The operation of the Test button is dependent on the panel status:

• If the panel is live without any alarm conditions, holding this button in for 10 seconds will enable the Fire Alarm bypass. The Fire Alarm interface will be ignored for 30 minutes to allow tests to be carried out.
• Following an alarm (prior to reset), holding the Test button for 5 seconds each will change the state of the Alarm 1, Alarm 2 and Fault relays.
