Ansul Autopulse 542 Conventional Panels

The AUTOPULSE 542 is a six-zone Releasing Control Panel for single and dual hazard applications. The AUTOPULSE 542 provides reliable fire detection, signaling and protection for commercial, industrial and institutional buildings. The AUTOPULSE 542 is compatible with System Sensor’s i3 detectors which are conventional smoke detectors that can transmit a maintenance trouble signal to the panel indicating the need for cleaning and a supervisory ‘freeze’ signal when the ambient temperature falls below the detector rating of approximately 45 °F (7 °C). In addition, the control panel is compatible with conventional input devices such as two-wire smoke detectors, four-wire smoke detectors, pull stations, waterflow devices, tamper switches and other normally-open contact devices. Refer to Device Compatibility Document for a complete listing of compatible devices.

Four outputs are programmable as NACs (Notification Appliance Circuits) or releasing circuits. Three programmable Form-C relays (factory programmed for Alarm, Trouble and Supervisory) and 24 VDC special application resettable and non-resettable power outputs are also included on the main circuit board. The AUTOPULSE 542 supervises all wiring, AC voltage, battery charger and battery level.

Activation of a compatible smoke detector or any normally-open fire alarm initiating device will activate audible and visual signaling devices, illuminate an indicator, display alarm information on the panel’s LCD, sound the piezo sounder at the panel, activate the panel alarm relay and operate an optional module used to notify a remote station or initiate an auxiliary control function.

The AUTOPULSE 542(E) releasing panel offers the same features as the AUTOPULSE 542 but allows connection to 220/240 VAC. Unless otherwise specified, the information in this data sheet applies to both the 110/120 VAC and 220/240 VAC versions of the panels.
