Envoy Installation, Commissioning & Operating Manual

SECTION 4 – COMMISSIONING

General

The commissioning procedures should be completed one step at a time as described below to avoid

unnecessary problems. By following a logical sequence any faults that may occur can be quickly

identified and rectified before moving on to the next step.

Before connecting external circuits to the control panel it is recommended that the panel is powered up

and tested, and any faults cleared before proceeding.

Ensure that 4K7 resistors are fitted into zone and sounder circuit terminals (see drg.no. S1597 on page

10) before applying power.

To clear the battery fault indication when the mains is connected, a battery must be connected to the

battery terminals; it is not possible to inhibit the battery fault by the insertion of a resistor.

The system may be operated on the battery supply, i.e. if the mains supply is not available.

Powering the Panel

Remove the fuse from the mains input. Connect the supply wiring to the terminal block. Check that all

connections are sound and that 4K7 EOL resistors are fitted to zone and sounder circuits.

Refit the fuse and switch on the mains supply. The panel LEDs are illuminated momentarily, the ARW

LED remains lit and a battery fault is indicated. The internal buzzer sounds.

Connecting the Battery

The standby battery comprises two 12V cells of a capacity suitable for the required standby period and

total alarm load.

Batteries may be located in the panel or in a separate cabinet depending on the battery size.

Battery leads are provided, including a battery link.

The SUPPLY HEALTHY LED should now be illuminated. The ARW LED should be illuminated and the

internal buzzer pulsing.

Turn the CONTROLS keyswitch to ON, and press RESET.

All the LEDs are lit momentarily, the ARW LED should extinguish and the buzzer should be silent. The

panel is now operating correctly in the quiescent mode.

Any faults that are indicated at this stage should be investigated and cleared before proceeding. If

necessary refer to the fault location chart on page 22 for further information.

If unfamiliar with the Surveyor ENVOY Series equipment, it is advisable to explore the panel operation

and become conversant with the controls before proceeding. Faults can be simulated by open and

short circuiting zone and sounder circuits, fire alarms can be generated by shorting the zone terminals

with a 470R resistor. Refer to the Operation section if required.

Disposal of Batteries

Respect the environment. Batteries must be disposed of responsibly and in ac-

cordance with any local regulations.
