General Description
The BEAMHKR allows the reflector of the System Sensor reflected beam
smoke detectors to operate in environments prone to the formation of con-
densation.
1
Condensation forming on the reflector may result in trouble or
false alarm conditions. BEAMHKR will lessen the likelihood of condensa-
tion by maintaining the reflector at a temperature that is slightly higher
than the surrounding air. The kit requires a 24V power supply. When used
with the long-range reflector kit (BEAMLRK), it is necessary to purchase
and install four BEAMHKR kits.
The kit includes the following parts:

Reflector Heater
Mounting and Wiring Instructions
1. Insure that the back of the reflector(s) is clean and free of debris.
2. See Figure 1 below (front view) for recommended mounting orienta-
tion. See steps 3 and 4 for additional information.
Electrical Specifications
Voltage:
15 to 32 Volts
Current:
450mA max at 32 V
(per reflector)
Power Consumption (per reflector):
Nominal:
7.7 W at 24 V
Maximum:
15 W at 32 V
3. Peel off the protective backing from the back of the heater. This
exposes the Pressure Sensitive Adhesive.
4. Observing proper orientation (see Figure 2), attach the heater to the
back of the reflector as shown. Insure that the four holes in the heater
are aligned with the four small holes on the back of the reflector. In
addition, insure that the heater tab is on the correct side of the reflec-
tor, as shown in Figure 1. Repeat for remaining three reflectors if using
BEAMLRK.

5. Mount the reflector(s). Refer to the installation manual provided with
the beam smoke detector for instructions. For installations in conjunc-
tion with BEAMLRK, refer to BEAMLRK installation manual for proper
mounting practices and considerations.
6. Attach heater wires to the power supply. For BEAMLRK, the four indi-
vidual heaters are wired in a parallel. See Figure 1.
NOTES:
1. 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.
