DESCRIPTION:
GRI presents the PRM-1, an incredibly exible appliance capable of monitory and open or closed loop
sensor using batter and/or external power (recommended). The PRM-1 makes use of local annunciation,
provides 2 form C relay outputs, a bi-color LED, and Onset button for reset and programming, and a built-
in testing function.
Used as a stand alone system, the PRM-1 can provide a local warning alarm with a ashing visual signal, or
be limited to a visual signal only. Should remote monitoring and/or equipment control be desired, the relay
output(s) may be connected directly to an alarm panel or wireless transmitter to provide monitoring. The
PRM-1 can also be connected to an on/o controller of a pump, blower motor or other similar appliance.
1) The sounder produces 85 dB at 9 volts DC at alarm. The audible alarm will also sound intermittently
to indicate low batter condition if voltage drops below 7.5 volts DC.
2) The green LED will ash every 60 seconds indicating normal operating conditions. It will also ash
once per second alarm during input shunt delay and also during user programming.The red LED will ash
rapidly indicating alarm. A slow ashing red LED indicates alarm activated, bur unit is in a timed alarm
reset mode.
3) When PRM-1 is in normal monitoring state, depressing and releasing the Onset button will start the
shunt time set. Depressing and holding the Onset button will place the PRM-1 into the test function. If
PRM-1 is in alarm, depressing and releasing the Onset button will silence the local alarm and reset the
relay output. The PRM-1 will then return to the normal monitoring state.
4) MODEL OPTIONS OFFERED:
Model with no sounder
Model with 1, 2 or 4 sensor inputs

INSTALLATION:
Upon removing the PRM-1 from the surface
mount box a knockout can be observed on the
back of the box for the exit/entrance of wires.
One can attach the surface mount case directly
to the wall or the PRM-1 may be mounted in a
single gang electrical box. Attach the sensor
wires to the terminal block TM1. The PRM-1
standard factory default programming is set
for Open Loop inputs, no alarm delay (instant
response) and a seven second manual shunt
time. To connect multiple sensors, contact GRI
at the number provided at the bottom of the
sheet. Optional external power of a 9 to 12 volt
DC can be connected to the terminal blockTM1
at Pins 1 and 2. Pin 1 for +DC, Pin 2 is ground. An optional remote reset function is available by connecting
a Normally Open momentary switch to TM1 Pin 3 and Pin 2. TM2 Pins 1 through 6 are used for 2 form
C relay outputs. Pins 1 and 2, and 4 and 5 for Normally Open contacts and Pins 2 and 3 and 5 and 6 for
Normally Closed contacts.

TEST MODE:
When the PRM-1 enters test mode, it tests the condition of the sounder by activating it with two short beeps. It
also test the condition of all LEDs by turning them on, and test the condition of the battery by disabling external
power and measuring battery voltage under a load. If a low battery is detected, the annunciator will sound 3 short
beeps 3 times, then the unit re-enters its normal monitoring mode.
