WARNING: NOT A LIFE SAFETY DEVICE - USE FOR PROPERTY PROTECTION ONLY
OVERVIEW
The GEMC-WL-HEAT and GEMC-WL-HEAT-2 are high-
quality 135°F (57°C) fixed temperature heat detectors with
Rate of Rise. Each detector incorporates circuitry that will
transmit an alarm signal upon an alarm condition, generate a
supervision test signal to the receiver and also monitor and
annunciate low battery. Coding switches are not required or
used. Each transmitter is assigned a unique identification
code number at the factory. The transmitter is powered by
one 3V Lithium battery (supplied) which can power the detec-
tor for up to two years. If the battery voltage drops below
normal, a low-battery report is sent to the receiver with any
status or alarm transmission. If a low-battery condition is
indicated, replace the battery.
UL 864 COMPLIANCE
The GEMC-WL-HEAT-2 is intended for use with GEMC se-
ries panel installations Certified to UL 864 10th edition using
firmware version 90.69 or greater. These versions of GEMC
series panels will detect an inoperative transmitter within 200
seconds and will annunciate/report the associated superviso-
ry trouble (E-04). The GEMC-WL-HEAT-2 is also Certified
for use in UL 864 9th edition versions of the previous GEMC
series panels. Do not use the GEMC-WL-HEAT (without the
"-2") with installations using the GEMC panels certified with
UL standard UL 864 10th edition as this will cause superviso-
ry troubles from the transmitter, generating an error report
within 200 seconds and then every hour. The GEMC-WL-
HEAT can be used in 9th edition installations that detect in-
operative transmitters within 4 hours and can also be used
with UL 864 10th edition installations when the AHJ approves
4-hour supervision with the GEMC control panel (versions
90.69 or greater) that are not programmed for "WL Fire 200
Sec. Supervision". Note: Both model detectors require at
least one GEMC-RECV in the system.
OPERATION
Rate-of-Rise Feature: A temperature increase of 15°F (-
9.5°C) or more per minute will result in an alarm
transmission. When the rate-of-rise element alone has been
activated, the detector is self-restoring.
Fixed Temperature: If the temperature of the center disk
rises to the detector's rated temperature (135°F / 57°C) an
alarm transmission will result. When actuated by the fixed
temperature element, the detector is non-restorable and must
be replaced. The need for replacement is indicated when the
center disk has fallen free; order System Sensor model
5601P to replace detector (upon replacement, you must fully
test the system and verify correct operation).
When the detector detects an alarm as described above, the
integral transmitter will send an alarm signal to the receiver.
A restore report will be sent when the condition clears.
*Protected coverage area is 50' x 50' ( 15.24m ) with a ten foot
( 3.05m ) ceiling height.
*Refer to NFPA 72 guidelines for spacing reductions when the ceiling height exceeds 10 feet (3.05m). (50 feet = 15.24m)

INSTALLATION INSTRUCTIONS
WARNINGS
• Heat detectors are not life safety devices. Use for property
protection only.
• Where life safety is required, smoke detectors must also be
used.
• Heat detectors should be electronically supervised with bat-
tery backup at the panel.
• The rate-of-rise mechanism may be subject to reduced sen-
sitivity over time. Annual testing of the rate-of-rise operation
is recommended.
• Refer to NFPA standard 72 for application requirements,
testing and maintenance.
• Do not paint the detector.
• A tamper zone trouble will result when the batteries are re-
placed.
SPECIFICATIONS
Input Power: Powered by a 3V lithium battery.
Fixed Temperature Point: 135°F (57°C).
Operating Frequency: 319.5Mhz
Step 1. Remove Mounting Base
Lift the detector from the base by turning the heat detector
counter-clockwise while holding the base stationary.
Step 2. Locate the RF ID#
On the rear of the unit, locate the RF ID# (see image on next
page) and accurately record the RF ID# in order to correctly
map the transmitter into the system (in Step 6).
