EPL12000 AUTOMATIC SOUNDER TO BEACON UNIT

INSTALLATION INSTRUCTIONS

INTRODUCTION

This unit is designed for use in areas where interruption by testing of the alert fire alarm signal is not acceptable - primarily, A.M.C’s (Auto Manual Centres) dealing with emergency calls. It may, of course, also be used in other areas dealing with calls from the public.

The unit is intended to replace existing sounders within the above areas. On receiving a fire alarm ALERT signal the unit will give a short adjustable alert signal before automatically changing over to a flashing beacon. When the EVACUATE signal is given the unit will automatically recommence sounding the evacuate signal for as long as it is present on the fire alarm system.

Only 24v, two wire or three wire systems will drive this unit.

Special units for 50v operation are available to special order.

1. FIXING

i) Remove the unit from its packaging and check there is no obvious damage.

ii) Remove the four small self tapping screws shown in Fig. 1 and remove the back plate with the sounder. Remove the required knockout and mount the unit using the fixing holes provided. iii) 2 WIRE SYSTEMS Fig. 2 Connect the sounder wiring circuit to terminals 1 and 2 of the connection block; if the polarity of the cabling is not known on two stage systems, then connect either way round and determine the correct polarity by testing the unit with operation of the fire alarm system. Reversed polarity will only cause the alert and evacuate signals to be reversed. This will not cause the unit to be damaged. When working correctly, the unit should give a short period of Alert signal (Approx. 5 pulses of the alert tone), followed by the silencing of the sounder and the commencement of the beacon for as long as the alert signal exists. On Evacuate the unit should give a continuous alternating signal (warble) for as long as the evacuate signal exists. 3 WIRE SYSTEMS Before connection ensure that the common negative wire has been correctly identified. Incorrect connection of the negative wire could damage the unit and possibly the fire alarm panel. The alert and evacuate positive connections should be connected as shown in Fig. 2. Reversal of these two connections will only result in the incorrect signal being given. If found to be incorrect, reverse these connections.

PERIOD OF ALERT SIGNAL BEFORE CHANGEOVER

This may be adjusted from approx. 1 to 11 seconds by adjusting VR1 as shown in Fig. 2.

VOLUME CONTROL

The sounder has an integral volume control, which may be adjusted by the installer over a range of about 20dB. To gain access to this, remove the two screws in the front of the sounder and pull the front of the sounder forward. The control is labelled ‘‘vol’’ on the Printed Circuit Board. No other controls should be adjusted.

TESTING

a) Alert Operation

Operate the fire alarm in the alert mode and check that the unit emits the alert tone for short period and it then changes over to beacon only as already described.

b) Evacuate Operation

Operate the fire alarm in the evacuate mode and check that the unit emits the evacuate sound, which is a continuous alternating signal.

Incorrect Operation

This is most likely caused by reversed connections.

STAFF AWARENESS

Having installed and tested the unit as specified, ensure that the staff within the area know that the unit is operational and what the signals mean. Normally the F.P.O. (Fire Precautions Officer) for the building will be responsible for the routine testing of the unit and he should be shown how to demonstrate the use of the unit and advised who to contact in the event of faults.

It is important that the Installation Card supplied with this equipment is completed and posted as soon as the equipment is installed. This will ensure that both user and installer are kept informed of equipment modifications etc.
