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 surround-
ing 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:

1 Transmitter/Receiver Heater Assembly
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.

NOTES:
1. The electrical current specified is the requirement for the heater only.
The power supply must be capable of powering the heater, and other
devices that may be supplied through the same terminals.
2. The heater is intended for the prevention of condensation only. It is not
intended to increase or reduce the specified operating temperature range
of the beam smoke detector.
