DESCRIPTION
The GEM-HEAT is a high-quality 135°F (57°C) Fixed tempera-
ture detector with Rate of Rise. It is compatible with the NAPCO
Express and Gemini series GEM-RECV Series supervised secu-
rity receivers..
The GEM-HEAT incorporates circuitry which will transmit an
alarm signal upon an alarm condition, generate an hourly supervi-
sory test signal to the receiver and also monitor and annunciate
low battery.
Coding switches are not required or used in the GEM-HEAT.
Each transmitter is assigned a unique identification code number
at the factory. The transmitter is powered by one 3 Volt Lithium
battery (supplied) which can power the unit for up to two years. If
the battery voltage drops below normal, a low-battery report will
be sent to the receiver with any status or alarm transmission. If a
low-battery condition is indicated, replace the
battery.
OPERATION
Rate-of-Rise Feature:
A temperature increase of 15
0
F 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
0
F / 57°C) an alarm trans-
mission 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 Chemetronics model 601 to replace detector.
When the GEM-HEAT detects an alarm as described above,
the integral transmitter will send an alarm signal to the receiver.
The alarm signal will be repeated every 10 seconds thereafter as
long as the alarm condition is present. A restore report will be sent
when the condition clears. Supervisory status reports are sent
from the GEM-SMK every hour.
Step 1. Remove the mounting base.
Lift the GEM-HEAT from the base by turning the heat detector
counter-clockwise while holding the base stationary.
Step 4. Mounting the base to the ceiling
Select mounting location for detector on ceiling. Do not locate
in direct path of hot or cold air flow. Remove the protective
insert from the base. Use the two screws and anchors pro-
vided to attach the mounting plate to the wall or ceiling.
Reinstall the the protective
insert into the base.
NOTE: The mounting
plate may be attached
to a
plastic
single-gang
electrical outlet box.
Do not attach to
metallic outlet
boxes.
Step 3. Install the battery
Observing polarity, install the supplied Duracell DL123A bat-
tery. Reattach the circuit board to the mounting posts using
the 4 Phillips head screws.
NOTE: If the Auto-Enroll
technique is to be used
to map the transmitter,
it must be done at the
point the battery is installed.
(Consult the control panel
installation instructions for
the Auto-Enroll procedure)

2.
Remove the circuit board
Remove the circuit board from the heat detector by removing
the 4 Phillips head screws and carefully lifting the circuit board
from the four mounting posts.
NOTE: The RF ID#
which appears on the
circuit board label
must be recorded in
order to map the
transmitter into the
system. (see Step 7)
