3825 Ohio Avenue, St. Charles, Illinois 60174

Receiver Unit of Reﬂected Beam Smoke Detectors

ELECTRICAL SPECIFICATIONS

Voltage: 15 to 32 V Current: 92mA max at 32 V1 Power Consumption: Nominal: 1.6 W at 24 V Maximum: 3 W at 32 V

GENERAL DESCRIPTION

The BEAMHK allows the transmitter/receiver of the reflected beam smoke detectors to operate in environments prone to the formation of condensation.2 Condensation forming on the beam detector unit may result in trouble or false alarm conditions. BEAMHK will lessen the likelihood of condensation by maintaining the unit at a temperature that is slightly higher than the surrounding air. The kit requires the use of an additional power supply for intelligent units that do not have the automatic test feature. Heaters used in conventional units, or intelligent units with the automatic test feature, will operate from a power supply already used to operate the beam unit.

The kit includes the following parts:

MOUNTING AND WIRING INSTRUCTIONS

1. Open front cover of the transmitter/receiver unit. Refer to the installation manual provided with the beam smoke detector for instructions.

2. Plug the transmitter/receiver heater assembly PCB into the provided slot on the optical assembly as shown in Figure 1. Insure that the connector is on the left side, and the resistors are facing outward as shown.

3. Plug the connector into pin-header labeled HEATER on the transmit-

ter/receiver PCB as shown in Figure 2. Pin orientation does not matter. Please insure that the connector is installed properly on all three pins, or the heater will not work.

4. Connect the heater power supply wires as described below. If adding

the heater kit to an existing installation, insure that the power supply connected to the beam detector is adequately rated for the additional power consumption of the heater.
