need to control pir alarm system with ir remote

It might seem weird but i am trying to make a theft alarm system using arduino which can be turned on and off using an ir receiver. Unfortunately a problem has come as you could have expected. I want to continue the theft search of pir sensor without requiring to put an input through ir remote. The issue is that since i am using ir in a conditional statement i need to put an input at the end of every loop. So it stops the pir sensor. Is there any way i can let my pir sensor work and stop it at any time i want. I have put the code below. Do not point out syntaxt errors please i have already uploaded and runned it please just help with the logic

Just posting your code so that people don't have to download it:

#include <IRremote.h>
int RECV_PIN = 11;
#define led 7
IRrecv irrecv(RECV_PIN);
decode_results results;

#include <SoftwareSerial.h>
SoftwareSerial gsm(2,3);
String outMessage = "intruder alert";
String destinationNumber = "+919835175453";
int ledPin = 13;                // choose the pin for the LED
int inputPin = 4;               // choose the input pin (for PIR sensor)
int pirState = LOW;             // we start, assuming no motion detected
int val = 0;                    // variable for reading the pin status
         //Set up a speaker on a PWM pin (digital 9, 10, or 11)

void setup() {
  pinMode(ledPin, OUTPUT);      // declare LED as output
  pinMode(inputPin, INPUT);     // declare sensor as input
  Serial.println("Enabling IRin");
  irrecv.enableIRIn(); // Start the receiver
  Serial.println("Enabled IRin");

void loop(){
   if (irrecv.decode(&results)) {
    Serial.println(results.value, HEX);
    if (results.value == 0xFF30CF){
              digitalWrite(led, HIGH);
              val = digitalRead(inputPin);  // read input value
              if (val == HIGH) {            // check if the input is HIGH
                digitalWrite(ledPin, HIGH);  // turn LED ON
                gsm.println("AT + CMGS = \"" + destinationNumber +"\"");
                //   gsm.println("AT + CMGS = \"" + destinationNumber1 +"\"");
                //     delay(1000);
                gsm.write((char)26); //ctrl+z
                Serial.println("Motion detected!");
                if (pirState == LOW) {
                    // we have just turned on
                    Serial.println("Motion detected!");
                    // We only want to print on the output change, not state
                    pirState = HIGH;
            } else {
                digitalWrite(ledPin, LOW); // turn LED OFF
                if (pirState == HIGH){
                // we have just turned off
                Serial.println("Motion ended!");
                // We only want to print on the output change, not state
                pirState = LOW;
    if(results.value == 0xFF18E7){
        digitalWrite(led, LOW);
   // irrecv.resume(); // Receive the next value
